Start-up (cont.)

Frequency converters

Proceed in the following order:

◗check that all lines supplying the load are off or that the load is disconnected;

◗close the upstream switch supplying Mains 1 power (on the LV switchboard);

◗close Mains 1 input switch Q1.

The system powers up:

◗red "load not protected" light 2 on the control panel goes on,

◗the rectifier-charger automatically starts;

◗close battery circuit breaker QF1 (systems equipped with a battery);

◗green "load protected" light 5 blinks for 3 seconds,

◗the inverter starts and awaits the start of the other inverters;

◗proceed in the same manner for each line;

◗when they are all on or enough have been started to supply the rated load, the output switch for each running line closes. The load is supplied and the connected devices can be started,

◗red "load not protected" light 2 goes off,

◗green "load protected" light 5 remains constant, on the control panel of each line supplying the load.

Parallel UPS systems with a Static Switch Cubicle

Proceed in the following order:

◗check that all lines supplying the load are off or that the load is disconnected;

◗close the upstream switches supplying Mains 1 and 2 power (on the LV switchboard);

◗close fuse switch Q2 in the Static Switch Cubicle (see figure 22);

◗close Mains 2 input switch Q4S in the Static Switch Cubicle;

◗close switch Q5N in the Static Switch Cubicle;

◗open maintenance bypass switch Q3BP in the Static Switch Cubicle;

◗close fuse switch Q1 in the Static Switch Cubicle;

◗close input switch Q1 on an UPS line.

The line powers up;

◗red "load not protected" light 2 on the line control panel goes on,

◗the RC automatically starts;

◗close the line battery circuit breaker QF1;

◗close inverter output switch Q5N for the line;

◗press the "inverter on" button 6 on the line control panel;

◗green "load protected" light 5 blinks for 3 seconds,

◗the inverter starts and awaits the start of the other inverters;

◗proceed in the same manner for each line;

◗when they are all on or enough have been started to supply the rated load power, the output switch for each running line closes and the load is supplied with power;

◗red "load not protected" light 2 goes off,

◗green "load protected" light 5 remains on, without blinking, on the control panel of each line supplying the load.

Start-up of a unit

Start-up of a rectifier/charger

◗it is recommended not to stop the rectifier/charger because the battery will no longer be charged. Rectifier/ charger start-up is automatic when Mains 1 input switch Q1 is closed;

◗red "load not protected" light 2 on the control panel goes on;

◗close battery circuit breaker QF1.
