6.3  Fitting the 7020A digital postioner

  

Disconnect actuator from power supply before starting work!

 Danger

1.  Remove the two screws indicated below.

2.  Replace the screws with the spacer bolts 

3. 

Place the adaptor panel onto the spacer bolts and the capacitor bracket and fix with 

the metal countersunk screws. IMPORTANT NOTE: The holes in the adaptor panel are 

not symmetrical; the outermost hole is at the top left (see right-hand photo below). The 

bottom right-hand hole remains unused.
