3.3 Installing the Maintenance Bypass Panel and UPS

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.

NOTICE!

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

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.
