3.2.4UPS Input Configuration

By default, the Liebert® APM™ ships with internal links installed between the bypass input and main (rectifier) input (single input configuration see Figure 48).

Figure 4 shows the Liebert APM in a split bypass (single source dual-input) configuration. In this configuration, the static bypass and the maintenance bypass lines are supplied by the same source using separate feeds. Both feeds must be protected externally with properly sized protective devices.

To wire the Liebert APM as a single source dual-input UPS, remove the links and wire the bypass feed to the bypass busbars, then wire the main feed to the main busbars (see Figure 6).

NOTES

1.Install in accordance with national and local electrical codes.

2.Input and bypass must share the same single source.

3.A neutral is required from the system AC input source. A full capacity neutral conductor is recommended. Grounding conductors are recommended.

4.Bypass and rectifier inputs and output cables must be run in separate conduits.

5.Control wiring must be run in separate conduits.

6.Optional 54-pole, 225A for 45kVA frame only or optional 54-pole, 400A for 90kVA frame only.

7.Customer must supply shunt trip breaker with 120V coil.
