This device complies with Directive 2014/34/EU and is suit-
able for use in explosion-hazardous areas acc. to EN IEC
60079-0:2018, EN IEC 60079-7:2015+A1:2018 and EN
60079-31:2014.In order to ensure correct operation to the in-
tended purpose it is required to observe the national regula-
tions and directives.

These devices may only be installed, connected and oper-
ated by trained and qualified staff. Qualified staff must have
knowledge of protection classes, directives and regulations
concerning electrical equipment designed for use in explosion
hazardous areas.Please verify that the classification and the
marking on the device comply with the actual application con-
ditions.
Avoid static charging of cables and plastic devices. Please
only clean the device with a damp cloth. Do not install the
device in a dust flow and avoid build-up of dust deposits on
the device.If the devices and the cable could be subject to
mechanical damage, they must be protected accordingly.
They must also be shielded against strong electro-magnetic
fields.The pin configuration and the electrical specifications
can be taken from the device marking or the technical data
sheet.In order to avoid contamination of the device, please re-
move possible blanking plugs of the cable glands or connec-
tors only shortly before inserting the cable or opening the ca-
ble socket.
Devices with terminal chamber (cable glands) have a weak-
er strain relief. Sufficient strain relief must be ensured or the
cable must be stationary-mounted.Do not disconnect the
plug-in connection or cable under voltage.Please attach a
warning label permanently in an appropriate fashion in close
proximity to the plug-in connection with the following inscrip-
tion: Nicht unter Spannung trennen / Do not separate when
energized.The device must be protected against any kind
of mechanical damage and degrading UV-radiation. This is
achieved through mounting in a standard T groove of a pneu-
matic cylinder.Load voltage and operating voltage of this
equipment must be supplied from power supplies with safe
isolation (IEC 30 364/UL508), to ensure that the rated volt-
age of the equipment (24 VDC +20% = 28.8 VDC) is never ex-
ceeded by more than 40%.
Repairs are not possible. The approval expires if the device is
repaired or modified by a person other than the manufacturer.
The most important data from the approval are listed.
