3)

Take off the fixing screws on each part

capacitor may be unavailable and

 

 

voltage may remain in some cases due

 

 

to trouble conditions, be sure to confirm

 

 

discharge of the capacitor.

 

 

2) Use a suitable resistive load (100/40W

Recommendation will check the voltage

 

 

with a DC volt meter.

 

 

NOTE

 

 

 

Do not discharge using a tool (e.g. screw-
