9.4.8. Protection of the switching filter
Protection of the switching filter is via the Q2 thermo-
magnetic circuit breaker.
To determine the reason for triggering of the Q2 ther-
momagnetic circuit breaker, perform the following
procedure:
1. Check that the capacitance of the switching
harmonics filter in each of the three phases is
adequate. Use a multimeter to measure the capaci-
tance between phases and check that all have the
same value. If not the case, proceed to replace the
filter.

2. If after taking the previous step above the problem persists, take note of the unit’s serial number and look at
what version of firmware it has. If you do not know what version of firmware the equipment has, it will be enough
to power the unit with DC and check it through display by: OK
Monitoring Status. The status will show digit
coding of the form _Letter, whereby the letter indicates the unit’s firmware version. With this information, call
Customer Service on the number on the cable protectors on the bottom of the unit’s door.
9.5. Replacing the electronics block
The unit’s main electronics boards (control board, power board, IGBTs, etc.) are its core element, and they are
grouped in a stainless steel cabinet known as the “electronics block”.
In case of equipment damage requiring the replacement of this “electronics block”, proceed as follows:
