Troubleshooting

Use Table 4-1 below to determine what condition triggered the error/warning
code on the unit's digital display, and what corrective action is needed.

Table 4-1, CSW1012 Inverter Error Codes

Code Condition
Unit has sensed the input is
voltage is low (<10.5 VDC)
E01
and unit will shut down in 30
seconds.
Unit has sensed the input
voltage is high and has shut
E02
down.
Unit output has sensed an
E03 overload or short circuit and
was shut down.
Unit has sensed the internal
temperature was high and has
E04
shut down.
Unit has sensed the input
voltage is low and has initiated
E05
a warning alarm (@11.2 VDC).
Unit has sensed that the
connected load is close to the
E06
overload shutdown limit.
Unit has sensed the internal
temperature is high, and is
E07
close to the thermal shutdown
limit.
Use Table 4-2 below to troubleshoot any of the listed problems/symptoms.

Immediately recharge the
battery (to at least 11.8 VDC),
and then restart unit.
Check the battery voltage, or if
an external charger is connected
to the battery bank.
Check the load connected to
the output. Reduce the load and
restart the unit.
Turn the unit off, and then wait
15 minutes before restarting.
Check if any object has blocked
the unit's air fl ow.
Recharge the battery (to at
least 11.8 VDC) as the unit will
shut down shortly.
Reduce the connected load.
Reduce the load and check if
any of the unit's ventilation is
blocked.
Symptom
The unit is off.
No power to
inverter.
GFCI was tripped.
Check error code
on the digital
display.

Corrective Action
Solution
Turn on the unit per
instructions in the
Operation section.
Check if fuse or disconnect
switch (if installed) is either
blown or turned off.
Check the connected load
and reset the GFCI.
Verify the error condition
and make the necessary
correction.
