3.11 Protection
The product provides complete protection for OVP, LVP, OCP, OPP, OTP, RCP, Fan Fail
and AMP Fail. When the protection is triggered, the product will immediately stop
the product output, and show the error code corresponding to the protection condi-
tion on the touch screen.
Please notice that if any protection is triggered, users shall eliminate the cause of the
protection condition according to the Table 3-11-1 before resuming the product
output. After eliminating the cause of the protection condition, users can press the
output & reset button on the front panel to unlock the protection, so as to resume
the product output.
Error code, possible causes and solution corresponding to the protection condition
are listed as below:
1. Load oscillation.
2. Problem of the voltage
feedbacking from the load
to the inverter circuitries.
3. Fault of the inverter con-
trol circuitries.
1. Remove the load to in-
spect the output voltage.
2. Seek the technical assis-
tance.
1. Load oscillation.
2. Incorrect wiring of the
terminals S

and S
N
when
setting voltmeter point to
EXT.
3. Fault of the inverter con-
trol circuitries.
1. Remove the load to in-
spect the output voltage.
2. Inspect the wiring of the
terminals S

tance.
When the output current
exceeds the maximum rated
current.
1. Decrease the output
voltage to fit the maximum
rated current
2. Remove the load to in-
spect the output current
When the output power
exceed the maximum rated
power.
1. Decrease the output
voltage to fit the maximum
rated power.
