section 3

AC POWER CONNECTION

This section describes how to ta p the po wer supply fo r local co nditio ns and h ow to wi re the mai ns lead. Do n ot con nect
the MAC 300 to an electrical dimmer system: doing so can damage the electron ics.

WARNING!

For protection from dangerous electric shock, the fixture must be grounded

(earthed). The AC supply shall have overload and ground -fault protection.

Changing voltage and frequency settings

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.

Disconnect the fixture from AC power. Unscrew and remove the cover from top of the base on the side
closest to the power inlet.

2.

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.

3.

Replace the cover.

Wiring the mains lead

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.

2.

Ver ify that the feed cable is undamaged and rated for the current requirements of all connected
devices.

Data Connection

section 4

DATA CONNECTION

This section describes how t o connect fixtu res to a control ler. The MAC 300’s 3-pin XLR connectors are configure d
for use with DMX-512 controller s. To reconfigure them for use wi th Martin Protocol controllers, see “Chang ing 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 capacitan ce and a charact eristic impeda nce of 85 to 1 50 ohms. The
cable must be electrically shielded and have at least 1 pair of twisted wires. The minimum wire size is 0.2 mm

2

(24

AWG) for runs up to 300 meters (1000 ft.), and 0.322 mm

2

(26 AWG) for runs up 500 meters (1640 ft.).

Adaptors

As many devices have 5- pin connectors and others have 3-pin connectors with reverse d si gnal polarity, adaptor cables
as shown below may be required. Insert a termination plug in the output of the last fixture on the link.

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 d ata out put; the n, conn ect a regu lar data cab le t o the swapper cable. Alternativel y, reconfig­ure the XLR pin-out as described on page19.

2.

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.

3.

Lead the data cable from the controller to the first fixture. Plug the cable into the fixture’s data
input socket.

4.

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.

5.

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.

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.
