Series 7400 Single Phase 1+N UPS

3.3.3Cable Connections

3.3.4Cabling Procedure

In the 25-40kVA UPS 1 PH models the input mains / bypass cables, UPS output cables and battery cables are connected to busbars located behind a safety cover just below the power isolator switches -as shown in figure 11. A terminal block is used for connecting the control cables to the battery circuit breaker and the external emergency stop facility.

For the 50 to 125 kVA 1PH models the power cables are connected either directly to their respective circuit breakers or to busbars, which are themselves, connected to the circuit breakers. See figure 12 – 14.

For 110V systems Static bypass isolator is located in auxiliary cubicles which is usually in scope of Emerson Network Power (India) Pvt. Ltd. Generally it is mounted in SCVS/ SVR cubicles. The cable connection details for the same are given in figures 15 – 18.

Once the equipment has been finally positioned and secured, connect the power cables as described in the following procedure. Study the connection diagrams in figures 19 & 20 and positively identify the diagram relevant to your equipment before commencing cabling.

1.Verify that the UPS equipment is totally isolated from its external power source and all the UPS isolators are open.

2.On each module, connect the input supply cables between the mains distribution panel and the UPS input mains terminals.

-ENSURE CORRECT PHASE ROTATION.

3.Connect the UPS bypass supply cables between the bypass distribution panel and the UPS bypass supply terminals on each module.

4.Connect the output terminals of both modules together (in parallel ).

-ENSURE CORRECT PHASE - PHASE CONNECTION (R - R & N - N).

Then connect the UPS output cables between the paralleled UPS output terminals and load distribution panel.

Note: If the UPS is to be commissioned before the load equipment is ready to receive power then SAFELY isolate the load cables.

5.On each module, connect the battery cables between the UPS battery terminals and its associated battery circuit breaker -see figures 19 & 20. As a safety precaution remove the battery fuse in the module until the arrival of the commissioning engineer.

- OBSERVE THE BATTERY CABLE POLARITY.

WARNING

Do not attempt to close the Battery Circuit Breaker before the equipment has been commissioned
