Key Takeaways
- Go through every manufacturer’s storage instructions before the gear leaves the factory, because switchgear, PDUs, UPS systems, and batteries don’t all need the same conditions.
- Store early equipment in a clean, dry, climate-controlled warehouse near the site. Schneider says even outdoor-rated switchgear isn’t suitable for outdoor storage.
- Count, inspect, and photograph every delivery before anyone signs, since Schneider puts the risk of loss on the buyer once its equipment leaves the plant.
- Keep batteries and warranties on a calendar. EnerSys wants DataSafe HX batteries refreshed within six months at 25°C (77°F), and Eaton’s 9395 and 93PM parts warranty ends 12 months after startup or 18 months after shipment, whichever comes first.
- Move the gear as few times as possible, and release it in install order once the room can protect it.
In the first piece of this series, the factory called to say your switchgear was done, and the site wasn’t ready for it. Project buffering is how you answer that call: you give the gear a controlled place to wait until the field can take it.
This piece, Part 2, is about the waiting part.
Once you’ve decided the switchgear isn’t spending the next six weeks in the laydown yard, a new set of questions shows up right away. What does each piece of equipment need while it waits? Who’s keeping an eye on the batteries? And how does it all get back to the site in the right order when the room finally opens up?
The manufacturers have already answered most of that. The answers are just buried in installation manuals nobody on a busy data center construction site has time to read. We pulled them into seven steps, from the day the gear is ordered to the day the crew calls for it.
Step 1: Find Out What Each Piece Needs Before It Leaves the Factory
Before anything leaves the factory, go through the storage instructions for every piece of data center equipment in the package. They’re usually a few pages into the installation manual, right after receiving and right before anyone stops paying attention.
Start with the switchgear. Schneider Electric says to treat its Masterclad switchgear as stored until it’s installed and running, in a clean, dry, climate-controlled space, and it says even the outdoor-rated version isn’t suitable for outdoor storage.
Then work through the rest, because they don’t all ask for the same thing. Vertiv’s Liebert TFX PDUs handle a wide temperature range but want humidity between 30% and 55%. Current Lighting’s garage fixtures are fine almost anywhere dry and covered. And Schneider’s NQ and NQM panelboard bulletin just says to store the equipment in the environment it was designed for, with no number attached.
That last bulletin is why it’s worth pulling the actual submittals for your project. It takes an afternoon, and it beats finding out at the dock.
Step 2: Pick a Warehouse That Can Actually Hold Those Conditions
With those submittals in hand, you’ll know what kind of building the gear needs, and that the jobsite isn’t it. A room without doors or HVAC can’t hold steady temperature or humidity, and Schneider’s QED-2 switchboard bulletin notes that outdoor switchboards aren’t weather resistant until they’re installed.
The jobsite is also an easy target. In August 2026, Fox 5 DC reported five people hauling more than $100,000 in copper wire spools off a data center construction site near Sterling, Virginia.
So look for a clean, dry, climate-controlled warehouse near the site, and watch the heat if batteries are in the package. C&D’s guidance on Mitsubishi Electric’s battery storage page says storage time on its pure-lead VRLA batteries halves for every 15°F above 77°F, and Dallas-Fort Worth hit 106°F on August 17, 2026, according to Fox 4.
Three Way’s Texas operation, with facilities in DFW and Austin, includes climate-controlled warehousing and trailers for the drive to site. It costs more than a dry corner and a lot less than replacing gear that sat in the wrong place.
Step 3: Check Everything at the Dock Before Anyone Signs
Once the gear gets to the warehouse, don’t let it disappear into storage before somebody gives it a proper look.
Match every crate to the packing list, check the packaging for dents, punctures, broken seals, or anything that looks shifted, and look at the shock indicators before the driver leaves. Take photos from every side too. If there’s damage or something’s missing, put it on the delivery receipt then and there.
That matters even more when the equipment may sit for months. A dent noticed in January is a lot harder to trace back to a November delivery.
The claim window can be short too. Vertiv wants damage to its STS2/PDU reported within 24 hours, while EnerSys limits responsibility for DataSafe XE shipments once they’re in storage. That’s why Three Way’s receiving team photographs deliveries as they arrive, before the crates ever get put away.
Step 4: Store Each Piece the Way Its Manufacturer Wants
After receiving is finished, the crates shouldn’t all get treated the same. The storage instructions now come from the manufacturer, and they can vary more than you’d expect.
ABB, for example, says to remove the shipping plastic from its SafeGear motor control centers and replace it with a moisture barrier. Vertiv says to leave the shrink wrap on its Liebert EXL S1 UPS.
Moisture is the big concern with switchgear, so heaters may need to stay on and cold equipment should warm up before it’s opened. Battery systems can add another layer. SMA wants its Storage XL cabinets indoors, upright, partly charged, and clearly identified.
A good warehouse should manage those differences piece by piece, not crate by crate.
Step 5: Keep the Batteries and the Warranty on a Calendar
A UPS can sit safely in storage and still lose something valuable while nobody touches it: battery life and warranty time.
That’s why the storage plan needs a calendar, not just a shelf location. EnerSys calls for a refresh charge on its DataSafe HX batteries within six months at 77°F, sooner when it’s warmer, and warns that ignoring those requirements can void the warranty. Samsung lithium-ion modules used by Mitsubishi Electric need voltage checks every six months too.
Warranty coverage can disappear just as quietly. Eaton’s 9395 and 93PM coverage runs 12 months from startup or 18 months from shipment, whichever comes first. Ten months waiting on the site leaves only eight.
Give one person those dates and make them part of the storage schedule from the start.
Step 6: Move It as Few Times as Possible
You can store the gear perfectly for six months and undo a lot of that work on move-out day. Every extra lift, transfer, and trip across a warehouse floor gives a several-thousand-pound cabinet another chance to take a hit.
Plan where it sits with the final move in mind. A Vertiv EXL S1 UPS module can weigh 4,667 pounds and shouldn’t tilt beyond 15 degrees, while Schneider recommends keeping Masterclad switchgear on its shipping skids until it reaches its final position. You don’t want either one shuffled around just to reach something parked behind it.
Keeping storage and final delivery under the same roof helps cut those handoffs. Three Way’s white-glove crews handle inside delivery and light rigging, while our rigging teams handle the heavier moves, so the gear can go from its storage position to the site with fewer hands and fewer opportunities for damage.
Step 7: Release It in the Order the Crew Will Install It
After months of protecting the gear in storage, the last step is making sure it reaches the electrical room in the order the crew can actually install it.
Build the release plan around the construction lookahead, not around whichever crates are easiest to pull. Masterclad lineups can arrive in one- or two-section splits, and larger lineups are installed from the center out. Send the wrong sections first, and you’ve done little else besides moving the delay from the warehouse to the jobsite.
Three Way’s sequenced deliveries tie each release to the install plan, so the right sections, accessories, and parts travel together when the room is ready for them. Using our asset-based fleet also keeps that release controlled through the final handoff, instead of introducing another carrier between storage and installation.
The Jobsite Is the Worst Warehouse on the Project
Long lead times are making this problem harder to avoid. Terrapin Construction Group data reported by IndustrialSage had 15 kV switchgear quoting 52 to 80 weeks in September 2026. You have to order early to protect the construction schedule, which means the equipment may arrive long before the electrical room can take it.
Three Way gives it somewhere better to wait.
Our data center logistics teams can receive the gear, document its condition, store it to the manufacturer’s requirements, manage the moves and maintenance while it sits, then release it in sequence when the site catches up. We operate facilities in Texas, Southern California, Northern California, and Oregon, with our own trucks covering the lower 48.
More importantly, warehousing, transportation, rigging, and crating stay under one plan. If the room date moves, you’re not calling four vendors to rearrange the job.

Frequently Asked Questions
Where Do You Store Switchgear and UPS Systems Before a Data Center Site Is Ready?
Store them in an enclosed, clean, dry, climate-controlled warehouse near the site. Schneider Electric says to treat equipment as if it’s in storage until it’s installed and operational, and that even outdoor-rated gear isn’t suitable for outdoor storage. Keep UPS batteries on their charging schedule.
What Is the Right Storage Temperature for Switchgear?
Schneider Electric’s Masterclad bulletin calls for about 70°F (21°C) in a clean, dry, well-ventilated space with no condensation and relative humidity at 75% or less. Other gear varies: ABB’s SafeGear motor control center manual allows 23°F to 104°F at 50% humidity or less.
How Long Can UPS Batteries Be Stored Before They Need a Charge?
It depends on chemistry and temperature. EnerSys DataSafe HX lead-acid batteries need a refresh charge within six months at 25°C (77°F), four months at 30°C (86°F), and two months at 40°C (104°F). Mitsubishi Electric lists voltage checks every six months for Samsung lithium-ion modules.
Does Storage Time Affect a UPS Warranty?
It can. Eaton’s 9395 and 93PM parts warranty runs 12 months from startup or 18 months from shipment, whichever comes first, so a long hold shortens coverage after startup. EnerSys also says failing to follow its manual, storage steps included, voids its warranties.
Who Should Inspect Electrical Equipment That Arrives Before the Site Is Ready?
Whoever takes custody, before it goes into storage. Match the packing list, check shock indicators and breaker crush cones, and photograph the equipment. Claim windows are short: Vertiv’s STS2/PDU manual asks for damage claims within 24 hours, and Schneider Electric allows 60 days for shortage claims.
