Caution!
Before connecting the supply voltage, note the following:
• The supply voltage must match that specified on the nameplate (1).
• Switch off the supply voltage before connecting the device.
• Connect the potential equalization to the ground terminal at the sensor.
!
Note!
• When using the probe in hazardous areas, the relevant national standards and the information in
the safety instructions (XA) must be observed.
• Use the specified cable gland only.

Connection recommendation
4.1.1
Potential equalization
Connect the potential equalization to the outer ground terminal of the housing (T13, F13, F16,
F17).
In the case of the stainless steel housing F15, the ground terminal (depending on the version) can
also be located in the housing.
For additional safety instructions, refer to the separate documentation for applications in hazardous
areas.
4.1.2
Electromagnetic compatibility (EMC)
Interference emission in accordance with EN 61326, Class B electrical device, interference
immunity in accordance with EN 61326 appendix A (industrial use) and NAMUR EMC
recommendation NE 21 (EMC).
4.1.3
Cable specification
The electronic inserts can be connected using the usual commercial instrument cables.
When using shielded instrument cables, it is recommended to connect the shielding on both sides
to optimize the shielding effect (if potential equalization present).
