Hipulse - Single Phase ‘1+N’ UPS System

130 kVA - 110V

Parallel 1+N:

Use of differential circuit breakers on UPS unit inputs in a configuration with separate inputs and one battery for each unit requires installation of a common device only on the System Bypass Mains.

Use of differential circuit breakers on UPS unit inputs sharing a common battery requires installation of device common to all the input lines. If inputs are configured for separate mains, a common device will also be required for all System bypass mains.

UPS Battery:

The UPS Battery is protected by means of a control circuit that operates the tripping mechanism of an automatic circuit breaking device (having a variable trip setting). The tripping mechanism using an undervoltage release coil that operates on a present minimum voltage level.

The circuit breaker is essential for maintenance of the battery and is normally located near to the battery installation. The characteristics and operation of the automatic circuit breaker are given in Chapter 6.

Output of the System:

In the eventuality that an external distribution panel is used for load distribution, the selection of protective device must proved discrimination with those that are use at the input to the UPS module.

3.1.7Cabling procedure

Once the equipment has been finally positioned and secured, connect the power cables as described in the following procedure.

Study the connection diagram in the figures below.

1.Verify that the UPS equipment is totally isolated from its external power source and all the UPS power isolators are open. Check that these supplies are electrically isolated, and post any necessary warning signs to prevent their inadvertent operation.

2.Open the door(s) to the UPS cabinet and remove the lower protective cover to gain access to the connections bars.

3.Connect the safety earth and any necessary bonding earth cables to the copper earth bus busbar located on the floor of the equipment below the power connections.

Note: The earthing and neutral bonding arrangement must be in accordance with local and national codes practice

Input Connections:

4.Connect the a.c. input supply cables to the input busbars (U1-V1-W1 terminals) and the bypass a.c. supply cables to the bypass busbars (U3 - N3 terminals) and tighten the connections.

ENSURE CORRECT PHASE ROTATION

Output System Connections:

5.Connect the system output cables between the output busbars (U2 - N2 terminals) and the critical load and tighten the connections.
