14.0SPECIFICATIONS

14.1System Configuration

The STS2/PDU can be set in several different configurations, according to the model and location. The configuration is set at the factory and does not need to be changed by the customer.

14.1.1Frequency

The STS2/PDU accepts input frequencies of 50 Hz or 60 Hz, depending on the model ordered. The fre- quency shall be within +/- 0.5 Hz of the nominal frequency.

14.1.2Input Voltage

The STS2/PDU models are available to handle various voltages. The input voltage must be three phase AC (3 wire-plus-ground). The voltage shall be within +/- 10% of the nominal voltage.

The following table provides nominal voltages, listed according to frequency.
