Option 2: Hard-wiring the power connections (optional)

Instead of using the power-plug, each column can be hard-wired to the service panel.

20 mm (3/4 in.) conduit from the service panel to each Large System column.

2At the column, connect the wires to the field wiring access block of the PDU according to the following:

•GND (ground) to the green wire

•L2 (neutral) to the white wire

•L1(hot) to the black wire

3Connect the wires to the hot, neutral, and ground connections at the service panel.
