15.0SPECIFICATIONS

This section provides the specifications for the Liebert STS2.

15.1System Configuration

The Liebert STS2 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. These configurations apply to both units, the Color Graphical Display and an LED Display.

15.1.1Frequency

The Liebert STS2 accepts input frequencies of 50 Hz and 60 Hz. The frequency shall be within

± 0.5Hz of the nominal frequency.

15.1.2Input/Output Voltage

The Liebert STS2 models are available to handle various voltages.

The input voltage must be three-phase AC (3 or 4 wire-plus-ground). The Liebert STS2 is designed to accept an input neutral from each source. The neutral is switched in the 4-pole Liebert STS2 only.

The voltage shall be within ± 10% of the nominal voltage.

The output voltage shall be three-phase AC (3 or 4 wire-plus-ground). Nominal output voltage shall be same as input voltage.

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