1. General

Safety regulations require that during a repair:

. Connect the unit to the mains via an isolation

transformer.

. Replace safety components indicated by the

symbol

Only by components identical to the original ones.

Any

Other component substitution (other than original

type)

May increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, you

must

Return the unit in its original condition. Pay, in

particular,

Attention to the following points:

. Route the wires/cables correctly, and fix them with

the

mounted cable clamps

. Check the insulation of the mains lead for external

Damage

. Check the electrical DC resistance between the

mains

Plug and the secondary side:

1) Unplug the mains cord, and connect a wire

2) Set the mains switch the “on” position (keep

3) Measure the resistance value between the

4) Repair or correct unit when the resistance
