Start-up (cont.)

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.
