Hipulse - Single Phase ‘1+N’ UPS System | 130 kVA - 110V |
WARNING
In ECOMODE the load is not protected against mains distortion.
1.2.5UPS Power Switch Configuration
Figure 1-2 illustrates the Hipulse UPS module in what is known as the "Split Bypass" configuration. In the Split Bypass configuration, the static bypass line is connected by a separate power switch to a dedicated 'bypass' power source which also feeds the maintenance bypass line. Where a separate power source is not available the Bypass (Q2) and Rectifier input supply connections would be linked together.
With the exception of maintenance bypass isolator, all the isolators shown must be closed during normal UPS operation.
1.2.6Battery circuit breaker
The battery should be connected to the d.c. busbar through a circuit breaker fitted inside the battery cabinet or located adjacent to batteries where a battery cabinet 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 detected faults. It also has a magnetic trip facility for overload protection.
1.2.7Battery temperature compensation
Hipulse UPS System offers a battery temperature compensation circuit. As the temperature inside the battery cabinet area rises, the d.c. busbar voltage reduces in order to sustain the battery at its optimum charge voltage. This must be used in conjunction with the battery sensor board.
1.2.8System Expansion
If necessary, a single
Note: System expansion should be carried out only by trained service personal. The individual modules connected to the system must be of the same power rating
