Start-up of a module
Start-up of a rectifier/
charger
◗ rectifier/charger start-up is automatic
when the normal AC input switch Q1 is
closed:
◗ ◗ the green "rectifier/charger" light 1
on the control panel goes on;
◗ close battery circuit breaker QF1.
Start-up of an inverter
When the rectifier/charger is on:
◗ press the "inverter ON" button 8 on
the control panel;
◗ ◗ the green "inverter" light 4 flashes.
Single-UPS unit
◗ the inverter starts, then, if the bypass
AC source transfer conditions are
satisfied, the load is transferred to the
inverter if the on-line mode is selected,
or the load remains on the static
bypass if the "ECO" mode is selected.
For on-line mode:
◗ ◗ the green "inverter" light 4 remains
on,
◗ ◗ the "static-bypass" light 3 goes off.
◗ For "ECO" mode:
◗ ◗ the green "inverter" light 4 flashes,
◗ ◗ the "static-bypass" light 3 remains
on.
Parallel UPS unit
◗ the inverter starts and awaits the start
of the other inverters;
◗ when they are all on or enough have
been started to supply the rated load
power, the output switch for each
running inverter closes and the load is
supplied with power:
◗◗ the green "static-bypass" light 3
goes off,
◗◗ the green "inverter" light 4 on the
control panels of the running inverters
goes on.
Single-converter unit
◗ the inverter starts up, then connects.
The load is then supplied by the
inverter:
◗◗ the green lights 4 and 5 go on.
Parallel-converter unit
◗ the inverter starts and awaits the start
of the other inverters;
◗ when they are all on or enough have
been started to supply the rated load
power, the output switch for each
running inverter closes and the load is
supplied with power:
◗ ◗ the green lights 4 and 5 on the
control panels of the running inverters
go on.
