Installation manual
•
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 its radiator.
•
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 is located
under the control board and the intake board as shown in the following pictures.
In terminal J18, do not connect wires coming into J18.1 and J18.2,
and use a multimeter to measure resistance between them. The resist-
ance measured should be approximately 5 kOhm at around 25 °C
ambient temperature.
Re-wire the NTC on the J18.1 and J18.2 connector and measure
resistance between connector pins themselves with the multimeter.
The resistance measured should be approximately 1 kOmh.
In case any anomaly in the inverter's NTC is found, contact technical
support.
