Ac Circuit Protection - Ingecon Sun 250 M220 Indoor Installation Manual

Installation manual
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".
If you do not have continuity, you should contact technical support.

block
To check the status of the protections, perform an in-depth check of section "6. Commissioning" in this document.
If the Ac circuit protection status is correct, proceed to verify their monitoring. To do this, you will need to check the
monitoring branches:
• Ac PROTecTIOnS
consisting of IQn2, IQn4, and IQAcn thermomagnetic circuit breakers.
note: x corresponds to the number of the inverter module that has shut down.
• ARReSTeR
consisting of IRVAcn (where n corresponds to the number of the inverter module that has shut down.
To check the Ac protection branch, you should see continuity between the ends of the monitoring circuit: Between
X7.1 and J19.6.
