Safety instructions

Follow the operating instructions, as failure to do so may
result in damage to both the unit and persons using the
equipment.
Ensure that the unit is isolated from any supply voltages
before installing or changing the equipment. Installation
should only be carried out by qualified personnel (due to the
IP 20 rating). When altering the settings of the units please
ensure that the unit is not connected to the monitored plant.
The design of the units corresponds to protection class II
(EN61010) except for the terminal blocks where protection
against accidental contact (safety from finger-touch to IP 20)
for operation by qualified staff is only guaranteed if the ter-
minals are completely inserted. 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.
If the unit has an external 24 V DC supply, this voltage has to
be generated and supplied externally according to the
requirements for safe extra-low voltage (SELV) since without
further measures this voltage is supplied near the operating
elements and at the terminals for the supply of connected
pulse pick-ups.
In case of malfunctioning of the unit or uncertainties please
contact the manufacturer. An unauthorised access of the unit
can lead to considerable risks for the safety of persons and
plant. It is not permitted and leads to an exclusion of liability
and warranty.
