Chapter 3 Electrical Installation

The presence of a radio frequency interference (RFI) suppression filter inside the UPS determines a residual earth current greater than 3.5mA and less than 1000mA.

Residual current circuit breakers (RCCBs) must be sensitive to DC unidirectional pulse (Class A) in the network and insensitive to transient current pulses. They are identified by the symbols respectively:

Figure 3-1 Symbols of residual current circuit breaker (RCCB)

These isolators must have an average sensitivity, possible adjustable between 0.3A and 1A.

It is recommended that the selectivity with every RCD be verified both upstream of the input distribution board and downstream (towards the load).

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.

Output of the system

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

3.1.7 Cabling Procedure

Once the equipment has been finally positioned and secured, refer to Figure 3-2 and Figure 3-3 to connect the power cables as described in the following procedures:

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 UPS door 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 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.

Common Input Connections

4.For common bypass and rectifier inputs, connect the AC input supply cables between the mains distribution panel and the UPS input supply busbars (U1-V1-W1-N1 terminals) and tighten the connections to 13 Nm (M8 bolt), and to

26Nm (M10 bolts). ENSURE CORRECT PHASE ROTATION.

Split Bypass Connections

5.If a split bypass configuration is used, connect the AC input supply cables to the input busbars (U1-V1-W1 terminals) and the bypass AC supply cables to the bypass busbars (U2-V2-W2-N2 terminals) and tighten the connections to 13 Nm (M8 bolt), to 26 Nm (M10 bolt), and to 50 Nm (M12 bolt). ENSURE CORRECT PHASE

ROTATION.

Warning

Ensure that any links () fitted between rectifier input and bypass busbars are removed. But do not remove those between the neutral terminals. See Figure 3-2 and Figure 3-3.
