PRODUCT DESCRIPTION

Rear Panel Receptacles

|
| The PDU comes from the factory with the rear panel receptacles (outlets) wires cable tied
| together; not connected inside the PDU. Depending on the type of PDU ordered, the outlet
circuits will come wired as two groups of four outlets or four groups of two outlets (Figure 5).
When installing the PDU, you must wire the receptacles for switched or un-switched
operation (explained below).
circuit. Wiring them to separate branch circuits maximizes the total available current and helps
balance the loads on the ac mains.
If the ac mains input includes a neutral wire, the outlets should be wired line-to-neutral as
shown. If there is no neutral wire, the outlets can be wired line-to-line. Never wire line-to-line
if the phase voltage is greater than 240 volts.
Switched Operation — For switched operation, wire the rear panel receptacles to the output
terminal block (Figure 3, page 5). In this configuration, the outlets are protected by 15-amp
| circuit breakers. They are called switched because they are under the control of the control board
| which opens and closed the contactor (see Figure 2, page 4).
| Un-switched Operation — For un-switched operation, wire the rear panel receptacles to the
| input terminals LL1, LL2 and NEU (Figure 4, page 7). In this configuration, the receptacles are
protected by 10-amp fuses in the input terminal block.
When wiring the outlet circuits, be sure to adhere to the stripping and torqueing specifications
in Table 5, on page 23.
