Power and Control Wiring

4.5 Power Supply

The STS2/PDU is supplied with redundant power supplies that are designed to operate from a voltage

range of 200V to 600V. The unit is set at the factory to match the nameplate voltage. Field adjust-

ments are not necessary. If the unit needs to operate at a voltage other than what is listed on the

nameplate, contact Liebert Global Services or your local Liebert representative. Table 6 provides

transformer tap information.
