2.Safety instruction
1. General safety
Safety regulations require that during a repair:
. Connect the unit to the mains via an isolation transformer.
. Replace safety components indicated by the symbol
components identical to the original ones. Any
only by
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 between
the two pins of the mains plug.
2) Set the mains switch the “on” position (keep the
mains cord unplug).
3) Measure the resistance value between the mains
plug and the front panel, controls, and chassis
bottom.
4) Repair or correct unit when the resistance
measurement is less than 1M
5) Verify
6) Switch the unit “off”, and remove the wire between
this, before you return the unit to the
customer/user (ref. UL-standard no. 1492).
