• for normal operation
Normal operation: LED green (OK),
floating changeover contact "Bat/OK"
to setting "OK" ("OK" means: Voltage
of the supplying power supply unit is
greater than cut-in threshold set at
the DC UPS module); Lack of buffer
standby:
LED red (alarm), floating
changeover contact "Alarm/Bat" to
setting "Alarm"; Battery replacement
required:
LED red (alarm) flashing with
approx. 0.25 Hz, floating changeover
contact "Alarm/Bat" switching with
approx. 0.25 Hz; Energy storage
> 85%: LED green (Bat > 85%),
floating NO contact "Bat > 85" closed;
Permissible contact current capacity:
DC 60 V/1 A or AC 30 V /1 A
