DISCONNECTING FROM THE MAINS SUPPLY

14.
This section describes the procedure for disconnecting the device from the mains network. If you want to work inside
the device (qualified personnel only), interventions must first be made on the protection elements upstream of the line
(both for the power level part and the power supply to the electronic board).

15.1. RESIDUAL CURRENT DEVICES

The residual current circuit breakers installed upstream of the station must be checked at least once every
6 months to make sure they are working properly. To do this, press the TEST key and make sure the device
actually trips.
