5.2  Connecting the P-73x to a Protective Earth Conductor 

 

 

INFORMATION 

 

In the case of P-73x stages with Sub-D connectors, ground loops can occur when 
the stage is grounded via its protective earth connector as well as by the shield of the 
connection cable for the electronics. 

  If a ground loop occurs, contact our customer service department (p. 35). 

  

 

INFORMATION 

 

  Observe the applicable standards for mounting the protective earth conductor. 

  

The P-73x is equipped with an M4 hole for fastening the protective earth conductor. 
This hole is located next to the cable exit and is marked with the protective earth 

conductor symbol 

 (see "Dimensions" (p. 41)). 

Prerequisite 

  You have read and understood the General Notes on Installation (p. 17). 

  The stage is 

not

 connected to the electronics. 

Tools and accessories 

 

Suitable protective earth conductor: Cross-sectional area of the cable 
≥0.75 mm

Supplied M4 protective earth screw set (p. 12) for connecting the protective 
earth conductor 

 

Suitable screwdriver
