Input cables

Enlarge the knock out hole for larger conduit

Note: The cutout on the top (or bottom) cover plate may need

to be enlarged depending on the installation requirements.

If the conduit size for your installation is too large for the conduit

access knock out, the hole must be enlarged.

Loosen the seven screws and remove the back panel.

Use an electrician’s punch to enlarge the knock out hole to the size

needed.

If power is run from the bottom of the rack, enlarge the knock out

hole in the bottom of the unit.

Install input cables

Loosen the seven screws and remove the back panel to gain access to

the compression terminals (the top and bottom cover plates can be

removed if necessary for easier access).

Connect the Protective Earth/Ground (PE/G), neutral (N), and line

(L1, L2, and L3) conductors to the appropriate compression

terminals and conduits.

Reinstall the any panels that were removed.

Please refer to the Power Distribution Modules Installation

sheet for information on how to install APC Power

Distribution Modules (PDMs).

Communication cables

Connect one end of the communication cable to the port on the back of

the unit and the other to the local area network.
