5.3.2 Bypass insulation transformer
It is used when the input line is without neutral, or the galvanic isolation between the
mains and the loads is required.
During normal operation the inverter transformer provides for this task, while during
the bypass condition the mains feeds the load directly. Generally the insulation
transformer is used when the output neutral conductor must be different from the input,
thus discriminating two different grounding systems.
5.3.3 Voltage adaptation transformers
A voltage adaptation transformer can be connected at the UPS output terminals to
adapt the standard output voltage to the value requested by the loads. It can also be
connected at the input terminals to adapt the actual mains voltage to the values defined
in the technical specification. In case the galvanic isolation is not required an auto-
transformer can be used.
5.3.4 Alarm card SRC (ALARM RELAY CARD)
Card SRC is an interface used to make the main UPS statuses and alarms available
on volt free contacts (NO/NC switching contacts).
During normal operation, without alarms, all the relays are energized.
