AV POWER switches can be equipped with additional devices. The user independently purchases this equipment and configures the AV POWER switch according to the specific requirements of the protected object. The methods of installing additional devices depend on the types of devices. Additional and emergency contacts, as well as trip coils, are installed in special sockets under a false panel, which is attached to the switch body with screws. Conductors from additional devices are routed to the switch body from the sides through special sockets. Electro- and manual drives are attached to the switch body. Communication modules and the indication and programming module are installed separately from the switch and are connected to it via the wires included in the kit.
