Typical application
Bat tery charge inhibition
Disables the recharging of the
battery, keeping the recharge
current to a minimum,
independently of the load.
This is done with the contact kept
closed; if reopened, the command
is cancelled.
When there is a generator, this
allows its output power to be used
only to supply the load and not
also to recharge the battery.
Inhibition of
synchronization with
backup mains
Disables the use of the by-pass line
and the synchronization of the
inverter. In the event of an
overload or fault, the UPS blocks
and the load remains unpowered.
This is done with the contact kept
closed; if reopened, the command
is cancelled.
To be used when the frequency of
the generator or of the backup
mains is highly unstable and it is
thus preferred to inhibit the
synchronization of the inverter.
Battery disconnector
contact
Activates the battery discharging
or disconnected alarm.
To be used to indicate the opening
of a battery switch located
external to the UPS.
A closed contact must be provided
when the external switch is
opened.
Displays the status of the battery
disconnector.
