9.4.2. Temperature
Code Alarm Reason for shutdown Description
0020H Temperature Power electronics temperature. The power electronics exceeds 80 °C.
Auxiliary temperatura sensor The auxiliary temperature sensor has triggered an alarm
In the event of a shutdown with reason “Motivo Paro Temperatura”, the first step is to check if the 0020H alarm
persists. If so, check the temperature of the unit’s radiator via the display menu:
MONITORING TempRad
• If the temperature displayed is close to or above 80 degrees, the unit has failed to inject power as a precau-
tion against a potentially damaging radiator temperature for the unit. The inverter will remain in this state until the
radiator has cooled, and then it will reconnect to the network.
If the problem occurs frequently, you should check the ventilation (fans and air intake grills) of the inverter and the
enclosure in which it is installed.
• If the temperature shown is less than 60 °C and the alarm persists, the problem could be in the thermal
switch built into the inverter in the electronic block heat sink.
• If the displayed temperature is abnormally low (compared to room temperature), the root of the problem
could be with the NTC built into the inverter.
Checking the NTC
To check the NTC of the unit you will need to access the J18 terminal of the intake board. This terminal can be found
underneath the control card.
In terminal J18, do not connect wires coming into J18.1 and J18.2,
and use a multimeter to measure resistance between them. The resis-
tance measured should be approximately 5 k
Ω
at around 25 °C ambient
temperature. It should be borne in mind that, for temperatures below
25 °C, the resistance reading will be greater than 5 k
Ω
, whereas for
temperatures above 25 °C, the resistance reading will be lower than 5
k
Ω . See below the characteristic curve of an NTC.
Re-wire the NTC on the J18.1 and J18.2 connector and measure resis-
tance between connector pins themselves with the multimeter. The
resistance measured should be approximately 1 k
Ω .
In case any anomaly in the inverter’s NTC is found, contact technical
support.

Checking the thermal switch
To check that the thermostatic switch is functioning properly, check for continuity between terminals X1.2 and x1.7 in
the upper left corner of the electronics block. The figure represents the entire terminal strip to identify it more easily.

If there is continuity between X1.2 and x1.7 proceed to check continuity between J19.2 and J12.1 in the intake board.
To locate the position of the terminals within the intake board, see explanatory drawing titled “Intake
board” on page 60.
If you do not have continuity, you should contact technical support.
