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. Check the state of fuses F6, F7 y F8, if they exist.
3. 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.
4. When the arresters have been checked, check that the Q1 thermomagnetic (AC circuit breaker of the inverter)
is ON.
In the event that Q4 is ON and none of the fuses F6, F7 and F8 are blown, the next step will be to ensure that both the
AC voltage intake XAC and the electronic block are powered. The procedure requires performing the following checks:
1. Check that the Q4 thermomagnetic circuit breakers are not damaged. With Q4 switched ON, measure the
flow resistance offered by Q4 for each phase. The resistance for each of the phases must be within the 60 to 70
Ohm range. The following figure details the test to be performed.

The figure has verified the resistance of phase 1, L1. Testing required for L2 and L3.
2. Check for continuity between Rcapt, Scapt and Tcapt terminals of the inverter’s Q4 thermomagnetic circuit
breaker and XAC terminal strip on the electronic block, according to the following sequence of terminals (see
figure):
• Rcapt – XAC.2.
• Scapt – XAC.3.
• Tcapt – XAC.4.
3. Check for continuity between the XAC terminal on the electronic block and the intake board as per the
following list:
• XAC.2 – J8
• XAC.3 – J7
• XAC.4 – J6
Another task to be performed is a visual inspection of the varistors on the intake board. Check that the thermal fuse
is not damaged.
The intake board varistors comprise a thermal fuse (FU) and a varistor (VA). The way to check that the varistor is
operating correctly is to perform the checks listed below:
Between pins 1 and 2, you must get a high impedance reading of around kOhm.
Between pins 2 and 3 you must get a reading of 0 ohms approximately.
