Inspecting And Unpacking The Ups Cabinets - Eaton 9E Installation And Operation Manual

• If using the power terminal wiring channel, keep interface wiring separate from power wiring or use shielded
wire.
• If using conduit, install the interface wiring in separate conduit from the power wiring.
• All building alarm inputs require an isolated normally-open contact or switch (rated at 24 Vdc, 20 mA
minimum) connected between the alarm input and common terminal. All control wiring and switch contacts
are customer-supplied.
• LAN and telephone drops for use with Mini-Slot connectivity cards must be supplied by the customer.
• The REPO feature opens all contactors in the UPS cabinet and isolates power from your critical load. Local
electrical codes may also require tripping upstream protective devices to the UPS.
• The REPO switch must be a latching-type switch not tied to any other circuits.
• A jumper wire must be connected between pins 3 and 4 on the REPO terminal block if using a normally-
closed REPO switch.
• REPO wiring should be a minimum of 0.5~2.0mm
• The REPO switch wiring must be in accordance with local regulations.
• The maximum distance between the REPO and the UPS cannot exceed 150 metres (500 feet).

Inspecting and Unpacking the UPS Cabinets

The cabinet is shipped bolted to a wooden pallet and protected with an outer wood container (see Figure 3-5).
The UPS cabinet is heavy (see Table 3-1). If unpacking and unloading instructions are not closely
followed, the cabinet may tip and cause serious injury.
1. Carefully inspect the outer packaging for evidence of damage during transit.
Do not install a damaged cabinet. Report any damage to the carrier and contact an
Eaton service representative immediately.
2. Use a forklift or pallet jack to move the packaged cabinet to the installation site, or as close as possible,
before unpacking. If possible, move the cabinets using the pallet. Insert the forklift or pallet jack forks
between the supports on the bottom of the pallet (see Figure 3-3 for the UPS cabinet centre of gravity
measurements).
Do not tilt the UPS cabinets more than 10° from vertical or the cabinets may tip over.
3. Set the pallet on a firm, level surface, allowing a minimum clearance of 3m (10 ft) on each side for
removing the cabinet from the pallet.
For the following step, verify that the forklift or pallet jack is rated to handle the weight of
NOTE
