5.2 FUNCTIONS OF THE SWITCHES FOR THE 10-40 kVA RANGE.
Input switch Q2.
The input switch provides the primary power supply to the UPS.
In normal operating conditions it should be in position
1 ON
.
The position
0 OFF
will cause the batteries to discharge.
In a configuration with separate mains, the switch only interrupts the rectifier power supply.
Output disconnecting switch Q6.
The disconnecting switch Q6 has three positions with the following functions:
•
Position 1 “UPS” : this is the position for normal operation of the UPS for a continuous power supply to the
load;
• Position 2 “MANUAL BY-PASS” : This position should only be selected for ordinary or extraordinary mainte-
nance operations (manual bypass); the load is connected directly to the mains power supply. It may be used
in the event of a UPS failure to power applications from the auxiliary mains while awaiting the intervention of
technical personnel;
• Position 0 “OFF” : This completely isolates the UPS output by removing the voltage from the applications in
any operating condition. It is used for the emergency shutdown of the system (internal E.S.D.).
Battery switch Q1 (UPS batteries).
When closed, this switch connects the batteries of the UPS to the DC/DC converter stage to power the inverter
in the event of a mains failure. The normal operating position is
1
(closed).
