6.13 Electrical insulation monitoring device operation test
Check the operation of the device that monitors the electrical insulation of the 220V power supply
(inverter) at the frequencies indicated in the general chart.
If the test is performed with the combustion engine running, the switch (1) in the console must be in
the "OUT 220V" position. This enables 220V voltage to be supplied to the socket alongside the console.
Using the special tool, remove the protective casing from the electrical panel (2) which holds the
electrical isolation control device (3). Find the monitoring device (3) and press the push-button installed
on the front of the residual current circuit-breaker (4), generally indicated by the word “test”.
This simulates an abnormal situation and automatic voltage release by the device.
