DISCHARGE PROCEDURE

 

 

 

WARNING

 

 

The machine has internal capacitors which are

 

charged to a high voltage during power-on condi-

 

tions. This voltage is dangerous and must be dis-

 

charged before the machine can be serviced.

 

Discharging is done automatically by the machine

 

each time the power is switched off. However, you

 

must allow the machine to sit for at least 5 min-

 

utes to allow time for the process to take place.

Carry out the following periodic controls on the power source:

• Clean the power source inside by means of low- pressure compressed air.

• Check the electric connections and all the connec- tion cables.

• Always use gloves in compliance with the safety standards.
