Devices with cable output
Observe the following minimum bending radii when laying the cable:
• Cable without venting:
static installation: 5-times the cable diameter
dynamic application: 10-times the cable diameter
• Cable with venting:
static installation: 10-times the cable diameter
dynamic application: 20-times the cable diameter
Devices with cable output and integrated venting
The PTFE filter at the end of the cable on the venting port may not be damaged or removed. For
the electrical connection it is preferable to use a shielded and twisted multicore cable.
Devices with ISO 4400 connector
Ensure that the cable connector is properly installed to guarantee the protection category
indicated! Ensure that the gasket supplied is installed between the plug and the cable connector.
After connecting the cable, fasten the cable connector to the device using the screw.
Devices with field housing
With these devices, the connection terminals are under the housing cover. To electrically
connect the device, the cover must first be unscrewed. Before screwing the cover back on, check
the O-ring and raised face on the housing for damage and replace if necessary! Screw the cover
back on by hand and ensure that the field housing is firmly closed.
