In the case of improper handling or handling malpractice, the electric safety of the device cannot be
guaranteed.
The local regulations or VDE 0100 (Regulations of German Electrotechnical Engineers) must be
observed.
Version 24V DC PNP (Protection class III): The Isolation of the connected power supply and the signal
output must cope with the regulations.
Use a fuse as stated in the connection diagrams (see pages G12).
In the case of a fault, the supply voltage must be automatically switched off by a RCCB protection
switch to protect against indirect contact with dangerous voltages.
A voltage disconnection switch must be provided near the device.
The electrical connections are made in accordance with the wiring diagram.
Compare the supply voltage applied with the specifications given on the electronic module and name
plate before switching the device on.
The screwed cable gland and closing element must have following specifications:
Ingress protection IP66, temperature range from -40°C to +70°C, UL or VDE certified (depending on
the country where the unit is installed), pull relief.
Make sure that the screwed cable gland safely seals the cable and that it is tight (danger of water
intrusion).
Cable glands that are not used have to be sealed with a blanking element.
All field wirings must have insulation suitable for at least 250V AC. The temperature rating must be at
least 90°C (194°F).
Provide protection for microswitch contacts to protect the device against inductive load surges.
The housing of the unit must be grounded to avoid static charging of the unit. This is particularly
important for applications with pneumatic conveying and non-metallic containers.
