4  Connecting to power supply

4.1  Preparing the connection

Always keep in mind the following safety instructions:

• 

The electrical connection must only be carried out by trained, 

qualified personnel authorised by the plant operator.

• 

If overvoltage surges are expected, overvoltage arresters should 

be installed.

Warning:

Only connect or disconnect in de-energized state.

Note:

Install a disconnecting device for the instrument which is easy to 

access. The disconnecting device must be marked for the instrument 

(IEC/EN 61010).

The voltage supply and signal output are connected via the spring-

loaded terminals in the housing.
Connection to the display and adjustment module or to the interface 

adapter is carried out via contact pins in the housing.

Proceed as follows:
The procedure applies to instruments without explosion protection.
1.  Unscrew the big housing cover
2.  Loosen compression nut of the cable gland and remove blind 

plug

3.  Remove approx. 10 cm (4 in) of the cable mantle, strip approx. 

1 cm (0.4 in) of insulation from the ends of the individual wires

4.  Insert the cable into the sensor through the cable entry
