3.2 Unloading the UPS Cabinets from the Pallet
W A R N I N G
S
The UPS cabinets are heavy (see Table A on page A-1). If unpacking instructions are not closely followed,
the cabinet may tip and cause serious injury.
S
Do not install a damaged cabinet. Report any damage to the carrier and contact your Eaton service
representative immediately.
S
Do not tilt the UPS or optional cabinets more than 10° from vertical or the cabinet may tip over.
NOTE Verify that the forklift or pallet jack is rated to handle the weight of the cabinet (see Table A on
page A-1 for cabinet weights).
Each UPS cabinet is bolted to a wooden pallet supported by wood skids.
To remove the pallet:
1. If not already moved, use a forklift or pallet jack to move the cabinet to the
installation site, or as close as possible, before unloading from the pallet. Insert
the forklift or pallet jack forks between the skids on the bottom of the unit.
2. Remove the hardware securing each UPS cabinet to the pallet.
3. Using a forklift, raise the UPS cabinet until the cabinet bottom clears the pallet by
approximately 3 mm (1/8”).
4. When the UPS cabinet is clear of the pallet, pull the pallet from under the
cabinet. Discard or recycle the pallets in a responsible manner.
5. Carefully lower the UPS cabinet until the cabinet base touches the floor.
6. Repeat Steps 3 through 5 for the remaining UPS cabinets.
3.3 Single Module Installation
To install a single module UPS system, perform the procedures in the following
paragraphs. If a multi‐module system is being installed, proceed to “Multi‐Module
Installation” on page 3-4.
3.3.1 Installing UPS Internal Power and Control Wiring
NOTE The cables used in Steps 2 through 4 are coiled inside the Input/Rectifier cabinet and are attached
at the factory to the rectifier output. The cables used in Steps 7 and 8 are coiled inside the Module Bypass
Cabinet (MBC) and are attached at the factory to the input of the MBC.
To install the UPS internal power and control wiring (see Table H on page A-16 for
tightening torques and paragraph A.4 starting on page A-22 for terminal locations):
1. Remove the plastic shield covering the inverter input section of the
Output/Inverter cabinet.
2. Route the DC Link cables from the rectifier output (Input/Rectifier cabinet) to the
inverter input (Output/Inverter cabinet) through the knockouts in the cabinet
sides.
3. Connect the positive DC Link power wiring to the inverter input. Connect two
cables to each inverter.
