FAULT –
Closed when the UPS encounters a fault condition, such as high dc
shutdown, short circuit, fuse/over-heat, overload shutdown, emergency stop,
inverter abnormal, bypass on shutdown. The contact is latched until manual
reset (off switch) or 30 seconds after the fault condition is removed.
SS –
Closed when the inverter static switch is conducting, open when the reserve
static switch is conducting (The two static switches will never conduct
simultaneously).
BYPASS –
Closed when the maintenance bypass breaker is closed, open when
the breaker is opened.
BACK-UP –
Closed when the inverter (running) is being backed up by the
battery.
BATL –
Closed when the inverter is using battery power and the batteries are
about to be exhausted.
