Since its introduction at PLASA in the fall of 1997, the MAC 500 has proven to be an extremely reliable luminaire. Thorough
attention to detail has resulted in a robotic light that is both compact and portable, and yet able to withstand the thumps and
bumps of touring.
Under the extreme conditions of heat and light, components do, however, occasionally wear out or require adjustment. This
manual is a guide to the most common service requirements. It is not intended as an exhaustive reference on how to trouble-
shoot and replace every single part.

Read the warnings and cautions below before servicing the fixture. Some adjustment procedures require that the case and/or
shell is removed while the MAC 500 is under power and the lamp is lit. They shall only be performed by qualified technicians
who are aware of, and can protect themselves from, the hazards involved in working with live circuits and discharge lamps.

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.
• Keep one hand in your pocket.
• Never touch any connector that carries voltage.
• Be careful with tools that conduct electricity.

Discharge lamps emit harmful ultraviolet (UV) light which can cause eye and skin burns. In addition, they work under high
temperature and pressure: lamps can and do explode. The explosion risk increases as the lamp ages and the quartz envelope
weakens. To reduce the risk of injury while working on a fixture with the cover removed:
• Never operate the lamp outside the reflector unit.
• Protect eyes with UV-blocking safety goggles. Do not look directly into the light.
• Protect exposed skin with a high factor sun-block.
