Caution!
• The protective ground connection must be established before any other connection is made.
A source of danger could arise if the protective ground connection is disconnected.
• Prior to commissioning, make sure the supply voltage matches the specifications on the
nameplate (left side of the housing).
• It is not permitted to connect a mixture of safety extra low voltage and voltage which poses a
shock hazard to the relays.
• Provide a suitable switch or power-circuit breaker in the building installation. This switch
must be provided within easy reach of the device and be labeled as a disconnector.
• An overcurrent protection unit (nominal current = 10 A) is required for the power cable.
