Installation manual
Only in the event of an insulation fault triggered by alarm 0400H will the AC power be switched off
and the DC power be left.
3.
Open the unit and find the section in this guide that deals with the alarm or reason for shutdown recorded
in the first step.
4.
Use a category III, 1000 V
proceed to carry out the checks listed here.
5.
If unable to solve the problem using this guide, take note of the unit's serial number and contact technical
service.
Below is a list of possible reasons for shutdown, their associated alarms and troubleshooting guidelines. If more than
one alarm takes place, the alarm on the display will be the sum of all active alarms.
E.g.:
9.4.1. Voltage and/or frequency out of range
One reason for shutdown associated with out-of-range voltage and/or frequency features the alarm codes listed below:

In the event of a 0001H and/or 0002H alarm, you must check the status of the Q4 thermomagnetic protection and
all the wiring associated with it. This check requires verifying the correct status of the following areas of the unit:
1.
Check that Q4 is in the ON position.
2.
Status of RVAC arrester located at the AC feed of the unit on the right. To verify its correct status, verify that
they are properly attached to their base and that the status window of none of them is red.
3.
Once the arresters have been checked, check that the Q1 thermomagnetic protection (AC circuit breaker of
the inverter) is ON.
In the event that Q4 is ON, the next step will be to ensure that both the AC voltage intake XAC and the electronics
block are powered. The procedure requires performing the following checks:
1.
Check that the Q4 thermomagnetic circuit breaker is not damaged. With Q4 switched ON, measure the flow
resistance offered by Q4 for each phase. The resistance of each of the phases must be within the 1 to 10 Ohm
range. The following figure details the test to be performed.
