Power Supply Settings For Electronic Ballast Version; Power Connection - Martin Professional MAC 2000 Profile User Manual

Power supply settings for electronic ballast version

In the MAC 2000 Profile with electronic ballast, the transformer must be tapped correctly for the local AC voltage. The
electronic ballast automatically adapts to the line voltage and frequency. The wrong transformer setting, though, can
cause overheating, damage, and poor performance. The factory setting is printed on the serial number label.
F U S E S
Electronic ballast models that come factory set for 100 V or 120 V have two 20 A T (time delay) main fuses, which are
located near the power switch. Units set at 210 V and above have two 15 A main fuses installed.
If you change the voltage settings, alternate fuses are supplied in bag packed together with this user manual. Use:
• 15 A main fuses when the transformer is set at 208, 230, or 250 V
• 20 A T fuses when it is set at 100, or 120 V
To change the tran sfor mer setting
1 Disconnect the fixture from AC power. Remove the rear base cover as shown in Figure 8.
2 Find the transformer setting in Table 3. Move the brown wire on the transformer connection block to the
position shown in Figure 10.
3 Close the base before applying power.

Power connection

Important! Connect the MAC 2000 Profile directly to AC
power. Do not connect it to a dimmer system;
doing so may damage the fixture.
You may need to install a cord cap that fits your supply on the
power cable. A 3-prong grounding-type plug must be installed following the manufacturer's instructions. 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.
To apply power, set the power switch on the base to the "I" position.
