Hipulse - Single Phase ‘1+N’ UPS System

130 kVA - 110V

8.3Operating Instruction

Starting and stopping the ‘1+N’ system is the same as a single module, however the module’s response depends on whether it is configured on the menu of the Operator Control Panel.

8.3.1System Start-up and shutdown procedures (Separate Batteries)

WARNING

If differential circuit breakers are used on UPS unit inputs, use a common device only on the system’s bypass mains. At the instant of electrical connection, the current may not be split instantaneously and this may cause the residual current circuit-breakers to trip separately.

These operations must be performed one at a time, progressing to the next step only after having completed the previous step on both UPS modules.

8.3.1.1 System Start-up

This procedure should be followed when tuning on the UPS from a fully powered down condition – i.e. where the load is not being initially supplied at all. It is assumed that the installation is complete, the system has been commissioned by authorized personnel and the external power isolators are closed.
