8.0WIRING CONNECTIONS

! WARNING

Verify that all incoming high and low voltage power circuits are de-energized and locked out before installing cables or making electrical connections.

All power connections must be completed by a licensed electrician experienced in wiring UPS equipment and in accordance with all applicable national and local electrical codes.

Improper wiring may cause damage to the UPS or injury to personnel.

! CAUTION

All shielded cables, non-shielded cables, non-shielded control wires, non-shielded battery breaker control wires and non-shielded remote control wires must be housed in individual, separate, steel conduits. Placing multiple cables in the same conduit with other control or power wiring may cause system failure.

NOTE

Use appropriately sized wire as a grounding conductor. Solid metal conduit is not a suitable ground conductor for UPS systems and could negatively affect system performance.

8.1Specific Connections

Refer to the drawings in this manual and any other drawings provided by Liebert for this installation. Make all of the following connections:

1.AC power cables from input power source circuit breaker (RIB) to each UPS Module Input. Observe phase rotation.

2.AC power cables from bypass power source circuit breaker (BIB) to UPS system bypass input at System Control Cabinet (SCC). Observe phase rotation.

! CAUTION

If there are line-to-neutral loads connected to the UPS output, the bypass input source must be wye connected and have three phases plus neutral plus ground. If the specified input is not available, an isolation transformer is required. Refer to 6.1 - Preferred Grounding Configuration, Wye-Connected Service, 6.3 - Preferred Grounding Configuration With Isolated Bypass and 6.4 - Alternate Grounding Configuration, Non-Isolated.

See 6.0 - Configuring Your Neutral and Ground Connections for an explanation of proper grounding techniques.

3.AC power cables from each UPS module output to SCC or to switchgear for critical load bus. Observe phase rotation.

4.Each UPS module must have its output neutral connected to the SCC for parallel operation. A minimum of a parity-sized neutral wire is recommended on this circuit for optimum system performance, regardless of the load configuration.

5.AC power cables from UPS System Control Cabinet (SCC) Output to critical load or maintenance bypass panelboard or switchgear. Observe phase rotation.

NOTE

If your installation includes a Maintenance Bypass Panelboard or switchgear, some or all power cables will be terminated in that equipment. Make sure all required wiring between the UPS system and this switchgear is completed per the submittal drawings. Observe phase rotation.
