… with cable gland 

 

Wiring work may only be performed with the power disconnected. 

For the wiring of the level sensor, proceed as follows: 

(1)

 

Unscrew probe head cap (1) using an open-ended spanner. 

(2)

 

Loosen union nut (2) of screwed cable gland (3).

Figure 10: Removable screw terminal 

(3)

 

Feed the two-core cable (4) into the union nut (2) and tighten the nut.  

The external diameter must be 5 to 10 mm. 

(4)

 

Remove screw terminal (5).  

(5)

 

Connect the two-core cable (4) to the (+) and (–) marked pols of the screw terminal 

(5).  

(6)

 

Plug the screw terminal (5) back on. The cable must have no traction. 

(7)

 

Configure reference points if necessary (see chapter 6.1). 

(8)

 

Screw probe head cap (1) back on. 

The earth connector on the underside of the probe head can be used for earthing or equi-
potential bonding.
