D section 1 SAFETY Thank you for selecting the Martin MAC 250 or the MAC 250+. Both the MAC 250 and the MAC 250+ are yokemounted profile spotlights that are designed around a 250 watt discharge lamp. They provide: · · · · · · · 12 saturated dichroic colors 8 replaceable rotating gobos 3-facet rotating prism variable focus strobe effects 0 to 100% dimming accurate 16-bit movement. In addition, the standard MAC 250 provides 4 user-configurable beam angles from 12.1° to 23.3°. The MAC 250+ provides gobo indexing, interchangeable color filters, and an 18.3° achromatic lens system. High-performance optics, attractive design, modular construction and numerous user-friendly features make these Martin fixtures well suited for any effect lighting application calling for a compact, hard-focusing 250 watt fixture. Safety precautions The MAC 250 and MAC 250+ are for professional use only. They are not for household use. They present risks of injury due to electric shock, heat and ultraviolet radiation burns, lamp explosion, falls, high-intensity light, and fire. Read this manual before powering or installing the fixture, follow the safety precautions listed below and observe all warnings in this manual and printed on the fixture. If you have questions about how to operate the fixture safely, please contact your Martin dealer or call the Martin 24-hour service hotline for assistance. · · · · · · ALWAYS disconnect the fixture from AC power before removing or installing the lamp, fuses, or any part; and when not in use. Allow the fixture to cool for at least 5 minutes before replacing the lamp. Keep all combustible materials (for example fabric, wood, paper) at least 0.3 meters (12 inches) away from the fixture. Keep flammable materials well away from the fixture. For protection against dangerous electric shock, always ground (earth) the fixture electrically. Use only a source of AC power that complies with local building and electrical codes. Do not expose the fixture to rain or moisture. Ensure that the air flow through fans and vents is free and unobstructed. When suspending the fixture above ground level, verify that the structure can hold at least 10 times the weight of all installed devices and secure the fixture with an approved safety cable. Block access below the work area whenever installing or removing the fixture. Refer any service operation not described in this manual to a qualified technician. Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture. Never place filters or other materials over the lens. Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F). Replace the lamp as soon as it becomes defective or worn out, or before usage exceeds the maximum service life. Do not stare directly into the light. Never operate the fixture without all lenses and covers installed: an unshielded lamp can explode without warning and emits dangerous UV radiation that can cause burns and eye damage. Do not modify the fixture or install other than genuine Martin accessories and upgrade kits. · · · · · · · · Safety 3 section 2 SETUP Unpacking The MAC 250 and MAC 250+ come with: · · · · 1 1/4-turn clamp mounting bracket 1 5-meter, 3-pin shielded XLR control cable 1 3-meter, 3-wire IEC power cable 1 user manual The packing material is carefully designed to protect the fixture during shipment - always use it or a custom flight case to transport the fixture. Lamp installation Compatible lamps The lamps listed in the table below may be used with the MAC 250 and MAC 250+. Installing any other lamp may damage the fixture.

Disconnect the fixture from AC power and allow the lamp to cool for at least 5 minutes before proceeding. Wear safety goggles to protect your eyes. reflector alignment screws lamp socket assembly Figure 1: Lamp installation 4 MAC 250 and MAC 250+ To i n s t a l l a l a m p 1. Remove the 2 Phillips screws from the lamp socket assembly. Pull the lamp and socket out of the head. 2. Remove the old lamp, if any, from the socket. 3. Holding the new lamp by its ceramic base (do not touch the glass), align the small pin with the small hole and insert the lamp squarely into the socket. Make sure that the 4 small projections on the base contact the face of the socket. 4. Clean the glass bulb with the cloth supplied with the lamp, particularly if your fingers touched the glass. A clean, lint-free cloth wetted with alcohol may also be used. 5. Gently insert the assembly, making sure the lamp fits through the opening in the reflector. Replace the 2 screws. 6. The reflector is pre-adjusted at the factory; however, precise alignment to compensate for variations between lamps may improve performance. See "Optimizing reflector alignment" on page 15. Pow e r i n g WA R N I N G ! For protection from dangerous electric shock, the fixture must be grounded (earthed). The AC mains supply shall be fitted with a fuse or circuit breaker and ground-fault protection. 1. Verify that the voltage and frequency settings match the local AC supply. The factory settings are printed on a label under the base. Check Table 7 on page 20 to verify that these settings are correct for your local AC voltage. Operating at the incorrect power setting can result in poor light output, greatly reduced lamp life, overheating and damage to the fixture. Refer to "Changing voltage and frequency settings" on page 20 if the settings need to be adjusted. 2. Install a grounding-type cord cap that fits your supply on the power cable. Following the manufacturer's instructions, connect the yellow/green wire to the ground (earth) pin, the blue wire to the neutral pin, and the brown wire to the live pin. The table shows some possible pin identification schemes; if the pins are not clearly identified, or if you have any doubts about proper installation, consult a qualified electrician. Wire brown blue yellow/green Pin live neutral ground Marking "L" "N" Screw (US) yellow or brass silver green Table 1: Cord cap wiring 3. Verify that the supply cable is undamaged and rated for the current requirements of all connected devices. 4. Plug the prepared power cable into the 3-prong IEC inlet and a grounded AC power supply. Do not connect the fixture to a dimmer system. Setup 5 Rigging The MAC 250 and MAC 250+ include a clamp mounting bracket to which 1 or 2 rigging clamps (not included) can be bolted. The clamp mounting bracket fastens to the base as shown with 1/4-turn fasteners. Figure 2: Clamp mounting bracket WA R N I N G ! Always use an approved safety cable. The 1/4-turn fasteners are locked only when turned fully clockwise. 1. V ...
