For AC-powered systems, use Procedure 5 on
ground/protective earth and logic return wiring, and to install ground and
alarm cabling for a UPS.
For AC-powered systems without reserve power, one input receptacle is
required per column, within 2.4 m (8 ft) of each pedestal. One IG-L6-30 or
L6-30 receptacle is required for each column. Instead of using the power plug
provided, the Power Distribution Unit (PDU) can be hard-wired to the power
source. In this case, #10 AWG conductors routed through 20 mm (3/4 in.)
conduit are generally used. The leads connect to the L1, L2, and GND
terminations on the field wiring terminal block on the PDU.
Note: Do not use ground fault circuit interrupt (GFCI) devices on
Large System AC power feeds.
