Warning!
Note that the entire electrical connection must be carried out only while the device is de-energized.

Caution!
• Before commissioning, ensure that the supply voltage corresponds to the specification on the
nameplate.
• Provide a suitable switch or power-circuit breaker in the building installation. This switch must
be installed close to the device (so that it is easily accessible) and marked as a circuit breaker.
• An overload protection unit (rated current = 10 A) is required for the power cable.
