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 Corrective Action
E01
Unit has sensed the input is
voltage is low (<10.5 VDC)
and unit will shut down in 30
seconds.
Immediately recharge the
battery (to at least 11.8 VDC),
and then restart unit.
E02
Unit has sensed the input
voltage is high and has shut
down.
Check the battery voltage, or if
an external charger is connected
to the battery bank.
E03
Unit output has sensed an
overload or short circuit and
was shut down.
Check the load connected to
the output. Reduce the load and
restart the unit.
E04
Unit has sensed the internal
temperature was high and has
shut down.
Turn the unit off, and then wait
15 minutes before restarting.
Check if any object has blocked
the unit’s air fl ow.
E05
Unit has sensed the input
voltage is low and has initiated
a warning alarm (@11.2 VDC).
Recharge the battery (to at
least 11.8 VDC) as the unit will
shut down shortly.
E06
Unit has sensed that the
connected load is close to the
overload shutdown limit.
Reduce the connected load.
E07
Unit has sensed the internal
temperature is high, and is
close to the thermal shutdown
limit.
Reduce the load and check if
any of the unit’s ventilation is
blocked.
Use Table 4-2 below to troubleshoot any of the listed problems/symptoms.
Table 4-2, Troubleshooting Guide
Problem Symptom Solution
No output voltage.
Status indicator is
off.
The unit is off. Turn on the unit per
instructions in the
Operation section.
No power to
inverter.
Check if fuse or disconnect
switch (if installed) is either
blown or turned off.
No AC output. Status
indicator is green.
GFCI was tripped. Check the connected load
and reset the GFCI.
No output. Status
indicator is amber.
Check error code
on the digital
display.
Verify the error condition
and make the necessary
correction.
