Safety instructions

Adhere to the installation instructions. Non-observance of the
instructions, operation which is not in accordance with use as
prescribed below, wrong installation or handling can affect
the safety of operators and machinery.
The unit must only be installed, connected and put into oper-
ation by a qualified electrician as during the installation dan-
gerous contact voltages may be exposed. The safe function of
the unit and the plant is only guaranteed when installation is
correctly carried out.
Disconnect the unit externally before handling it. Also discon-
nect any independently supplied relay load circuits.
Be careful when operating the connected unit. This is only
allowed by qualified personnel due to the protection rating IP
20.
The design of the unit corresponds to protection class II
(EN61010) except for the terminal blocks. Protection against
accidental contact (safety from finger contact to IP20) for
qualified personnel is only guaranteed if the terminals have
been completely inserted. Therefore the unit must always be
mounted in a control cabinet of at least IP 54 which can only
be opened using a tool.
For DC units the external 24 V DC supply must be generated
and supplied according to the requirements for safe extra-low
voltage (SELV) since this voltage is provided near the operat-
ing elements and at the terminals for the supply of sensors
without further protection measures.
In case of malfunction of the unit or queries please contact the
manufacturer. Tampering with the unit can seriously affect the
safety of operators and machinery. This is not permitted and
leads to an exclusion of liability and warranty.
