INTRODUCTION
SCOPE
This document describes replacement and adjustment procedures for the MAC 2000 Performance framing and
zoom/focus modules. The procedures in the MAC 2000 Wash service manual may be used to service the
CMYC module, yoke, and base.

PRECAUTIONS
RISK OF ELECTRICAL SHOCK
Warning! Always disconnect the fixture from AC power before and while servicing.
Removal of any cover exposes connectors that carry lethal electric currents. While working on a fixture under
power:
• Make sure the fixture is electrically grounded.
• Use a supply with ground-fault-interrupt protection.
• Never touch any connector that carries voltage.
• Be careful with tools that conduct electricity.
RISK OF UV RADIATION AND LAMP EXPLOSION
Discharge lamps emit harmful ultraviolet (UV) light that can cause eye and skin burns through direct exposure.
They also work under high pressure that occasionally causes them to explode. To eliminate the risk of injury
from the discharge lamp,
• Never operate the lamp with covers or lenses removed.
• Do not look directly into the light.
ELECTROSTATIC DISCHARGE
Printed circuit boards (PCBs), individual ICs, and Hall sensors can be damaged by electrostatic discharge
(ESD). To avoid damaging these ESD sensitive parts:
• Ensure that you and your tools have the same potential (ground) as the fixture before and when handling any of
the above components.
• Store PCBs in antistatic (electrically conducting) bags and store ICs in antistatic foam.
• Power off the fixture and allow capacitors do discharge before removing or inserting components on the PCB.
INDUCTIVE LOADS
Power off the MAC 2000 Performance before connecting or disconnecting step motors. Failure to do so can
damage the motor drivers.
