Ground

 

1) 

Ground must be done before operating the positioner. 

 

2) 

Open terminal cover and there is an internal ground bolt on the left of terminal plate. When using 

internal ground, use 2 mm wrench to loosen locking bolts of the terminal box cover. An external 

ground bolt is located next to the conduit entry. Please make sure that the resistance is less than 

100ohm.   

 

3) 

When  using  external  ground,  use  (+)  screw  driver  to  unscrew  the  ground  bolts.  Insert  external 

ground bolts and spring washer into ring type terminal of the ground cables and tighten them with 

bolts.
