Installation

3) Use four T20 torx screws and washers to fasten the conduit box to the front legs of the UPS

NOTICE!

Place flat washer, lock washer and screw in this particular order.

4)After all UPS wiring has been completed, attach conduit box cover to the front of the conduit box

5)Use hook and loop fasteners to attach the base covers to the UPS

3.3Installing the Maintenance Bypass Panel and UPS

IMPORTANT!

If you do not have an APC Maintenance Bypass Panel, you must provide overcurrent protection and a UPS input AC disconnect means.

APC strongly recommends that a means of bypassing the UPS from the critical load be provided for maintenance.

Follow these guidelines when installing the Maintenance Bypass Panel and UPS:

Install the Maintenance Bypass Panel within sight of the UPS. When installing the Maintenance Bypass Panel, see illustrations under Wiring Diagram for BC300 and any instructions provided with the Maintenance Bypass Panel.

Install all wiring in accordance with applicable electrical codes. Use 75° C copper conductors.

Install the AC input and UPS output in separate conduits. UPS output circuits must be installed in dedicated conduit systems and separate from other electrical circuits.

Control wiring must be installed in a separate conduit.

Good ground connections are necessary to reduce electrical noise and make the operation of the UPS and the loads safe. Follow the grounding guidelines in the installation wiring diagram. Refer to the National Electrical Code (NEC), appropriate IEEE documents, and all applicable codes.

For systems with non-linear, neutral-connected loads, standard practice is to size the neutral conductor for 1.732 times the phase current.

When installing the AC wiring, refer to the illustration Single Line Diagram for BC300 and to any additional diagrams provided with the UPS. The illustration shows typical installations. Your installation may be different.

See Component Overview illustration for a view of the UPS with covers removed. See Wiring Termination or Component Overview illustrations for UPS wiring terminations. Refer to illustration External Connection Board for information on the external connection board. See illustration Communication Interface Board (Option) for information on the optional communication interface board.
