Item Problem Cause Remedy
1 Unit does not start. 1) Input not present. 1) Apply the input power by closing the
feeder or wall breaker.
2) Measure and Verify that the input voltage
is correct,
IF correct turn the input Breaker CB 1,
to“ ON ”,
3) Verify Green LED, “ AC ”, is “ ON ”.
2) Input is not connected
properly.
1) Measure and Verify that the input voltage
is on the correct terminals
of TB 1.
2) See Section 3 - 11, Electronic Tray, input
& output wiring for the correct terminals.
2 Unit is very quiet, no noise. 1) Fan or fans are not running. 1) With CB 1 “ OFF ” check from the front if
the fan rotors are free to turn.
If jammed replace Electronic Tray.
2) Check if the fan 2 wires are connected.
3) Verify Input power as in Item # 1
3 Unit shuts-off, immediately
or within few minutes of
input power failure. 1) Battery Tray not connected or
Battery Breaker CB 2 “ OFF”.
1) Verify Black plug, P3, from Battery Tray
is connected into Battery Jack, J 3, on
Electronic Tray.
2) Verify Battery Breaker, CB 2, on front of
Battery Tray is “ ON ”.
2) Batteries are discharged. 1) Verify if the Red LED, “ Low Battery “
Warning is “ ON ”. Run the unit for over
24 hours to bring the batteries up to
proper charge.
2) Verify if the Green LED’s Battery Voltage
indicators, “ HB ” to “ FB “ are “ ON ”.
Run the unit for over 24 hours to bring
the batteries up to proper charge.
3) Batteries are discharged. 1) Verify by disconnecting the Battery Tray
Plug, P 3, from Electronic Tray Jack, J
3, & Measure that the DC Voltage at the
Plug with CB 2 “ ON “ is correct.
2) Red to Black terminal shall be 46.0 VDC
for 650 watt unit from the Battery Tray.
3) Red to Black terminal shall be 70.0 VDC
for 1300 watt unit from the Battery Tray.
4) Measure the Electronic Tray Jack, J 3,
has the correct DC voltage with no load.
5) Red to Black terminal shall be 53.0 VDC
for 650 watt unit at the Electronic Tray.
6) Red to Black terminal shall be 80.0 VDC
for 1300 watt unit at the Electronic Tray.
J 3 voltage low then replace the
ELECTRONIC TRAY.
7) Run the unit for over 24 hours to bring
the batteries up to proper charge.
