1.2.4UPS Power Switch Configuration

1.2.5Battery Circuit Breaker

Figure 2 illustrates what is known as the “Split Bypass” configuration. This is the standard configuration for all 1PH Models

In the “Split Bypass” configuration the static bypass line is switched by a separate isolator to a dedicated ‘Bypass’ power source which also feeds the maintenance bypass line.

The power switch locations in the various 7400 models are shown in Figure 3.

With the exception of the maintenance bypass isolator, all the isolators shown must be closed during normal UPS operation.

Although it cannot be classified as a ‘power’, the reset switch may be used as a part of the UPS operating procedure. Fitted to the UPS Logic Board, the reset switch is used by the operator to re- transfer the load to the inverter following a detected overload or overtemperature fault.

The battery is connected to the DC Busbar through a circuit breaker fitted inside the battery Cabinet / Rack or located adjacent to the batteries where a battery Cabinet / Rack is not used. This circuit breaker is closed manually, but it contains an undervoltage release coil which enables it to be tripped from the UPS control electronics following certain detects for faults. It also has a magnetic trip facility for overload protection.
