AC-powered systems

For AC-powered systems, use Procedure 4 on page 82 to install safety 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.
