NOTICE

The device does not have a power switch

‣ You must provide a protected circuit breaker in the vicinity of the device.

‣ This must be a switch or a power-circuit breaker and you must label it as the circuit breaker for the

device.

‣ At the supply point, the power supply for the 24 V versions must be isolated from dangerous live

cables by double or reinforced insulation.
