Always disconnect the fixture from AC power and allow it to cool before installing the lamp. To protect against lamp explosion, allow a hot lamp to cool for at least 5 minutes before removing the lamp socket. reflector alignment screws lamp socket assembly Figure 1: Lamp installation 1. 2. 3. Remove the 2 Phillips screws from the lamp socket assembly. Pull the lamp and socket out of the head. Remove the old lamp, if any, from the socket. 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. 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. Gently insert the assembly, making sure the lamp fits through the opening in the reflector. Replace the 2 screws. Please see "Optimizing reflector alignment" on page 19 to optimize light output. 4. 5. 6. Lamp Installation 5 section 3 A C PO W E R C O N N E C T I O N This section describes how to tap the power supply for local conditions and how to wire the mains lead. Do not connect the MAC 300 to an electrical dimmer system: doing so can damage the electronics. WA R N I N G ! For protection from dangerous electric shock, the fixture must be grounded (earthed). The AC supply shall have overload and ground-fault protection. C h a n g i n g vo l t ag e a n d f r e q u e n cy s e t t i n g s The factory settings are printed on the serial number label under the base. These settings must match the local AC power supply as closely as possible! Operating at the incorrect power setting can result in poor light output, greatly reduced lamp life, overheating and/or damage to the fixture. 1. 2. Disconnect the fixture from AC power. Unscrew and remove the cover from top of the base on the side closest to the power inlet. Locate the 7-terminal connection block. Move the wires to the terminals that most closely match local conditions as shown in Table 1. If the local voltage falls halfway between settings, use the higher voltage setting. For example, use the 120 V setting if your voltage is 110 V. Replace the cover. 100 V 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz BLUE BROWN 3. 120 V 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz BLUE BROWN 210 V 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz BLUE 230 V 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz BLUE 250 V 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz BLUE 50 Hz BROWN BROWN BROWN BLACK BLACK BLACK BLACK BLACK BLUE BROWN 60 Hz BLACK 0V 20 V 120 V 230 V 250 V 60 Hz 50 Hz BLUE BLUE BLUE BLUE BROWN BROWN BLACK BROWN BLACK BROWN BLACK BLACK Table 1: Voltage and frequency settings Wiring the mains lead Wire brown blue yellow/green Pin live neutral ground Marking "L" "N" Screw (US) yellow or brass silver green Table 2: Cord cap wiring 1. Install a grounding-type cord cap on the mains lead. Connect the yellow/green wire to ground (earth), the brown wire to live (hot), and the blue wire to neutral. Table 2 shows some possible pin identification schemes; if you have any doubts about proper installation, consult a qualified electrician. Verify that the feed cable is undamaged and rated for the current requirements of all connected devices. 2. 6 AC Power Connection section 4 DATA CONNECTION This section describes how to connect fixtures to a controller. The MAC 300's 3-pin XLR connectors are configured for use with DMX-512 controllers. To reconfigure them for use with Martin Protocol controllers, see "Changing the XLR pin-out" on page 19. XLR PIN-OUT Pin 1: shield Pin 2: signal - Pin 3: signal + Recommended cable Use cable designed for RS-485 devices with low capacitance and a characteristic impedance of 85 to 150 ohms. The cable must be electrically shielded and have at least 1 pair of twisted wires. The minimum wire size is 0.2 mm2 (24 AWG) for runs up to 300 meters (1000 ft.), and 0.322 mm2 (26 AWG) for runs up 500 meters (1640 ft.). Adaptors As many devices have 5-pin connectors and others have 3-pin connectors with reversed signal polarity, adaptor cables as shown below may be required. Insert a termination plug in the output of the last fixture on the link. 5-pin to 3-pin Adaptor Male 1 2 3 4 5 Female 1 2 3 3-pin to 5-pin Adaptor Male 1 2 3 Female 1 2 3 4 5 3-pin to 3-pin Phase-Reversing Adaptor Male 1 2 3 Female 1 2 3 Termination Plug Male 1 2 3 120 P/N 11820005 Construct P/N 11820006 P/N 91613017 Figure 2: Cable adaptors and termination Building the data link 1. DMX controllers: Connect a data cable to the controller's data output. If controller has a 5-pin female socket, use a 5-pin male to 3-pin female adaptor cable (P/N 11820005). Martin RS-485 protocol controllers: First, connect a 3-pin "swapper" cable (P/N 11820006) to the controller's data output; then, connect a regular data cable to the swapper cable. Alternatively, reconfigure the XLR pin-out as described on page 19. 2. 3. 4. If convenient, you may split the link into branches using a splitter such as the Martin 4-Channel Opto-Isolated RS-485 Splitter/Amplifier. Do not use a "Y" connector to split the link. Lead the data cable from the controller to the first fixture. Plug the cable into the fixture's data input socket. Connect the output of the fixture closest to the controller to the input of the next fixture. If connecting to another type of fixture with reversed-polarity (pin 3 cold), insert a swapper cable between the two fixtures. Continue connecting fixtures output to input. Up to 32 devices may be connected on a serial link. If more fixtures are required, use another controller output, if available, or an RS-485 amplifier. 5. 6. Terminate the link by inserting a male termination plug (P/N 91613017) into the data output of the last fixture. A termination plug is simply an XLR connector with a 120 ohm, 0.25 W resistor soldered across pins 2 and 3. If a splitter is used, each branch of the link must be terminated.
