990-7032A, Revision 3 7/01 4
The 5000 VA models (without batteries installed) require two people to lift due to their weight.
Load the UPS into the Rack
Supporting the UPS from the front and back,
carefully align the unit with the rails. Slide the UPS
into position.
Attach the Mounting Brackets to the Rack
Use the ornamental screws supplied with the UPS to
attach the mounting brackets to the rack post.
2. Hardwire the Electrical Connection
Caution:
The electrical connection must be made by an authorized electrician according to national and local regulations.
Verify that the supply line contains a 25 Amp circuit breaker BEFORE hardwiring the UPS.
Ensure that the batteries are not installed in the UPS until the hardwiring is complete.
Incorporate a readily accessible disconnect device in the fixed wiring design.
1. Select the appropriate wire size and connectors. For most applications, #10 AWG (5 sq. mm) wire should be
sufficient.
2. The input wiring terminal is located on the rear panel of the UPS. Remove the access door by unscrewing the single
screw which holds it in place.

3. Slide the wire input plate to the left on rack mount units and up on towers and remove it. This will expose the input
wiring terminal.
4. Use a screwdriver or any hard object to detach the circular knockout. You may need to use pliers to fully detach the
knockout.
5. Feed the wire cable through the hole in the wire input plate. Using a threaded lock nut, fasten the plate to the selected
cable or conduit connector.
6. Use a knife or pliers to strip off the plastic on the end of the cable to expose the copper wire. Strip all three wires.
7. Use a flathead screwdriver to connect the wires to the terminal block inside the UPS. Loosen the screw, then feed the
copper wire into the terminal block and tighten the screw. Connect the protective earth ground to the terminal block
at the position marked with the ground symbol (
). The UPS wiring color code is:
GREEN for GROUND
WHITE for NEUTRAL
BLACK for HOT
8. Once all the wires are connected to the terminal block, reconnect the wire input plate to the UPS. Align the plate,
position it into the grooves, and slide it to the right.
9. Inspect the connections and location of the excess wires before installing the access door.
10. Replace the access door and fasten with the screw (removed in step 2).
