AC Power Connection

section 3

AC POWER CONNECTION

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.

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.

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.

Wiring the mains lead

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.
