electrician as during the installation dangerous contact voltage occurs
and the safe function of the unit and the plant is only guaranteed when
installation is correctly carried out.

e careful when handling the connected unit. Due to the protection rating
IP 20 this is only allowed by qualified staff.
T
he design of the unit corresponds to the protection class II except for the
terminal blocks where protection against accidental contact (safety from
finger-touch to IP20) for operation by qualified staff is only guaranteed if the
terminal screw has been completely screwed in. This is why the unit always
has to be mounted in a control cabinet of at least IP 54 which can only be
opened by means of keys.
I
n case of malfunction of the unit or uncertainties please contact the manu-
facturer. Tampering with the device can seriously affect the safety of peo-

ity and warranty.
