Protection Of The Switching Filter; Replacing The Electronic Block - Ingeteam Ingecon Sun Power Series Installation Manual

Ingeteam Power Technology, S.A.
To verify that the emergency stop button works properly, check for continuity between
terminals X3.8 and J17.1, and between terminals X3.9 and J17.2.

9.4.8. Protection of the switching filter

Switching filter protection is achieved by thermomag-
netic switch Q3 in units with a transformer and Q2 in
TL units..
The Q2 or Q3 thermomagnetic circuit breaker belongs
to the switching filter. The way to determine the reason
for shutdown of the Q2 or Q3 thermomagnetic circuit
breaker will be by performing the following procedure:
1. Check that the protection in question is
turned to maximum. If not the case, calibrate it to
the maximum and check operation.
2. If the problem persists, check that the
capacitance of the switching harmonics filter
in each of the three phases is adequate. Use a
multimeter to measure the capacitance between
phases and check that all have the same value. If
not the case, proceed to replace the filter.
3. If after taking the 2 steps 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
the letter indicates the unit's firmware version. Ensure that the firmware version is letter N or later. Once you have
all this information, call technical service. on the number on the cable protectors on the bottom of the unit's door.

9.5. Replacing the electronic block

The unit's main electronic 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:
The electronics block is a heavy element. We suggest that it be carried by two people or with mechan-
ical assistance.
When handling the block, personal protective equipment (PPE) must be worn: helmet, goggles and
safety boots.
The tools needed to replace the electronics block are:
• Flat screwdriver for terminal connections.
