safety in electrical installations.

leakage
relay loses its protection capacity. The last order from the relay is to open the installation in the event of this
power supply problems to the equipment itself or through lack of voltage in the installation (neutral or face fault).

externally (AUTOMATIC SWITCH).
2. The equipment is set by programming by pressing the Std/+ key in positive safety mode. The "+"symbol appears
