36V Power Harness
Power Supply
Laser Assembly
Do not attempt to repair a damaged 36V power harness if the
wiring insulation is damaged through chafing, nicks, or cuts, or if
the wires were overheated due to an over-current machine error.
Never handle the 36V power harness unless power to the machine
is completely disconnected. Do not rely on the power switch to
break the power supply to the machine.
Lethal voltages exist inside the power supply unit, at the back side
of the electrical supply input connector, and in the wires between
the two. If you plan to do any work with any of these components,
turn the power switch off and disconnect the electrical input
supply cord from the machine.
It is very important that the power cord is plugged into a properly
wired electrical outlet. Failure to have a properly wired outlet may
result in damage to the equipment and personal injury. It is
recommended that a licensed electrician be consulted to ensure
that the electrical outlet is properly wired and grounded. If a
properly wired electrical outlet is not used for the source supply
voltage to the system, electrical failures may result.
Do not attempt to disassemble the power supply unit for any
reason. There are no user-serviceable components inside. Internal
components in the power supply unit might still have residual
voltage (even if power is disconnected) that can cause painful
electrical shock.
Do not attempt to replace or service any component in the rear of
the lower bed without disconnecting the A/C power input cord.
Failure to do so will leave the power supply and power switch
energized with dangerous levels of voltage even when turned off
and can result in severe injury from electrical shock.
The laser assembly replacement procedure is intended to be
performed only by specially trained Melco service technicians and
personnel. Disassembly by untrained individuals will void any
warranty protection and can result in personal injury or damage
to the machine.
DO NOT install laser assembly until the machine is turned OFF!!!
Failure to turn the machine off may result in personal injury or
damage to the machine.
The laser light adjustment procedure is intended to be performed
only by specially trained and authorized Melco service technicians
and personnel. Disassembly by untrained individuals will void any
warranty protection and can result in personal injury or damage
to the machine.
