Installation / Commissioning
These devices may only be installed, connected and operated 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 conditions.
Installation and mounting instructions
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 remove possible blanking plugs of the cable glands or connectors only shortly before in-
serting the cable or opening the cable socket.
Special conditions for safe operation
Devices with terminal chamber (cable glands) have a weaker strain relief. Sufficient strain relief must be ensured or the cable must be station-
ary-mounted.
The terminal chamber has to be closed correctly after working on the device. Dust congeries inside the housing is to be avoided.
Do not disconnect the plug-in connection or cable when energised.
Cables and cable intakes that are not used must be sealed with the delivered blank plug.
The device must be protected against any kind of mechanical damage and degrading UV-radiation. When installed in a TURCK protective hous-
ing type SG-DSU35TC or SG-DSU35V this requirement is fulfilled.
Protection against transient overvoltage has to be ensured by the power unit.
service / maintenance
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.
