3 4) Bad Batteries. 1) Verify by measuring the DC Voltage at
the Battery Tray Plug, P 3, has changed
after 24 hours of charging.
2) Red to Black terminal shall be 46.0 VDC
for 650 watt unit.
3) Red to Black terminal shall be 70.0 VDC
for 1300 watt unit.
REPLACE BATTERY TRAY.
4 Red lights on the unit. 1) “ ALM ” Red light is “ ON ”. 1) Inverter failure is indicated.
REPLACE ELECTRONIC TRAY.
2) “ LB ” Red light is “ ON ”. 1) Batteries have been discharged to a low
battery level condition. Very little or No
back-up power is available in case of
sustained or future input failures.
2) Run the unit for over 24 hours to bring
the batteries up to proper charge.
3) “ OL ” Red light is “ ON ”. 1) Unit has exceeded it’s full load capacity
and is Overload condition.
Reduce the output load.
2) Unit has auto shut down mode and will
turn “ OFF ” after 30 seconds.
5 No Output. 1) Output is not connected
properly or Output Breaker
CB 3 is “ OFF ”.
1) Turn Output Breaker CB 3 to “ ON ”.
2) Measure and Verify Output voltage is on
the correct to terminals of TB 3.
3) See Section 3 - 11, Electronic Tray, input
& output wiring for the correct terminals.
6 Unstable Output 1) Wrong frequency selection 1) Verify the Red Frequency jumper is on
the terminals of TB 3.
2) See Section 3 - 10, Electronic Tray
wiring Illustration 3 - 4 for the correct
terminals.
