Connecting An External Dimmer System - Martin Professional MAC TW1 User Manual

Connecting an external dimmer system

DANGER! Make sure that any external dimming system used with the MAC TW1 is
connected to ground (earth) and protected by overload and ground fault (earth leakage)
circuit breakers. Check that the dimming system and cables are correctly rated for the
power and current requirements of the lamp, and check that the lamp voltage rating
matches the dimming system output voltage.
Important! Connect lamp power from an external dimming system via the Neutrik
PowerCon® connector on the connections panel only.
Power can be supplied directly to the MAC TW1 lamp by an external dimming system, simplifying grouped
dimming control in installations with existing fixtures and dimming circuits.
The MAC TW1 has an intelligent lamp power system that blocks power to the lamp from an external
dimming system unless the fixture is powered on, has reset and is operating correctly.
The external dimming power cable must be fitted with a Neutrik PowerCon® NAC3FCA cable connector for
connection to the MAC TW1. If the dimming cable does not already have this type of connector, it can be
obtained from your Martin supplier (P/N 05342804). The pinout is marked on the connector. Connect the
terminal marked

To connect an external dimming system:
1. Isolate the MAC TW1 and external dimming system from power.
2. Check that the external dimming system is correctly rated for the power and current requirements of the
lamp, and that a lamp with the correct voltage rating for the external dimming system's output voltage is
installed in the fixture.
3. Connect the external dimming power cable via the Neutrik PowerCon
connections panel. To plug the cable in, line up the raised tab on the cable connector with the keyway in
the chassis connector, push the cable connector in and twist clockwise to lock.
4. Move the Lamp Power switch on the connections panel to the External position.
5. Apply power to the MAC TW1 and allow it to reset.
6. Once the MAC TW1 has reset successfully, you can supply power to the lamp from the external dimming
system.

To disconnect an external dimming system:
1. Isolate the MAC TW1 and external dimming system from power.
2. See Figure 4. Check that a lamp with the correct voltage rating for the internal dimmer is installed in the
fixture.
3. Disconnect the external dimming power cable from the PowerCon
connections panel. To remove the cable connector, pull back the latch to release the lock, twist the
connector counterclockwise and pull out.
4. Move the Lamp Power switch on the connections panel to the Internal position before applying power to
the MAC TW1.
