Thermomagnetic Q2; Replacing The Inverter - Ingeteam Ingecon Sun 250 TL Installation Manual

Ingeteam Energy, S.A.
To verify that the emergency stop button works properly, check for continuity between
terminals X3.8 and x1.7, and between terminals X3.9 and J19.8.
See illustrations on pages 72 and 76.

8.4.8. Thermomagnetic Q2

The Q2 thermomagnetic circuit breaker belongs to the
switching filter. The way to determine the reason for
shutdown of the Q2 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 capac-
itance of the switching harmonics filter in each of the
three phases is adequate. Use a multimeter to meas-
ure 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 3 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 Monitoring
show digit coding of the form _letter, whereby the let-
ter 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.

8.5. Replacing the inverter

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
mechanical 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.
• Ratchet and spanner 17 (M12) for AC and DC connections.
