WARNING

 

The supply common (pin 5) and the screen (pin 6) must be 
connected to the supply unit with protective ground. 
Incorrect connection, incorrect polarity, or inadmissible supply 
voltages can damage the gauge. 

 

 

 
 

 

Reassemble the connection socket. 

 
 

 

Plug in the connection socket. 

Secure the connection socket on 
the gauge with the screw 
(tightening torque 

0.2 Nm).
