Hipulse - Single Phase '1+N' UPS System

Operating 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.
8.3.1 System 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.
