Electrical connection

Danger due to electric voltage
‣ T he entire process of electrical connection must be carried out while the system is
de-energized.
‣ B efore commissioning, compare the supply voltage to the specifications on the nameplate to
ensure that they match.
‣ P rovide a suitable switch or power-circuit breaker in accordance with IEC/EN61010 within
the building installation. This switch must be fitted near to the device (within easy reach)
and must be marked as a circuit breaker.
‣ An overcurrent protection device (rated current of ≤ 10 A) is required for the power cable.
• Note the terminal designation on the side of the device.
• Mixed connection of safety extra low voltage and voltages that are dangerous to touch
to the relay/SSR is permitted.
In the case of a device for use in a hazardous area:
Note the information in the Ex documentation (XA).
