24 | Mounting
When connecting/switching a device that can be hazardous when
malfunctioning, an additional safety measure is required.
– If this device is installed to control a load that can cause a danger in the event
of malfunction, additional safety measures are required. Make sure that all
devices are connected according to their instruction manuals. Under certain
circumstances the connection to another device (e.g. protective conductor to
ground) can cause extreme surges.
– Keep the device away from spray- or rainwater, dust and direct sunlight.
– When mounted in industrial facilities, the accident prevention regulations for
electrical systems and equipment of the professional associations must be
followed.
– In schools, training centers, clubs and workshops the operation of modules
must be monitored by responsible, trained personnel.
– If the device needs to be repaired only genuine spare parts may be used! The
use of other components may result in serious personal injury and damage.
– When the mains plug of the device is inserted into a correctly mounted,
230 V, earthed socket (connect without load), the lighting of the seven seg-
ment display signals the operational readiness of the device.
