XP600/1100/2000 INSTALLATION AND OPERATION MANUAL
When input voltage to the
inverter exceeds set limits, the inverter will immediately and
without warning shut off. When input voltage returns to normal
range, the inverter will immediately restart. Since high over
voltages tend to have very fast edges, the inverter must shut
down quickly to protect itself. This kind of fault usually occurs if
the battery is suddenly disconnected from the system and the
battery charger continues to supply current.
When battery voltage falls to
within 2% to 4% of low line voltage, the LOW BAT/THERM buzzer
will sound. If the condition continues without reducing load to the
inverter or adding charge to the battery, the inverter will shut off.
When voltage rises to approximately 85% of nominal battery
voltage the inverter will turn back on and the alarm condition will
clear. The inverter can be manually reset by cycling the on/off
switch. This will reset the protection circuit and turn the inverter on
at any voltage above minimum voltage.
The inverter is also
protected against overheating. It will provide its full rated output
up to the temperature listed in the specification sheet. If it is
subjected to higher ambient temperatures or air circulation is
blocked, the inverter may overheat. If the LOW BATT/THERM
buzzer sounds, immediate action is required or the inverter will
shut down. Either reduce load, or provide more cooling in the
immediate environment. If no action is taken, the inverter will
likely shut down within 2 minutes. When the inverter shuts down,
the alarm condition will persist and the cooling fan will continue
to run. Since the inverter has eliminated its load, it will cool fairly
quickly. It will automatically restart when it has cooled sufficiently,
and the LOW BATT/THERM alarm will clear.
