The MAC 500/E has 4 fuses. The main fuse is located on the power-switch panel and may be replaced without opening the fixture.

The fuses for each of the 3 low-voltage power supplies are located on the printed circuit board. If one of the circuit board LEDs does not light, one of these fuses may be blown.

1.Remove the printed circuit board.

2.Locate and replace the defective fuse with one of the same rating. The fuses are shown on the PCB layout diagram and their values are listed in the specifications.

3.Replace the printed circuit board.

1.Disconnect the MAC 500 from AC power. Remove the top covers.

2.Find the correct transformer and ballast terminals for your AC supply in the table below. Consult a qualified electrician if you do not know the AC frequency and voltage.

AC Supply		Transformer		Magnetic Ballast
Frequency	Voltage	Voltage	Terminal	Setting	Terminal
50 Hz	200-210 V	210 V	4	200 V / 50 Hz	7
50 Hz	210-220 V	210 V	4	230 V / 50 Hz	10
50 Hz	220-235 V	230 V	6	230 V / 50 Hz	10
50 Hz	235-240 V	230 V	6	245 V / 50 Hz	12
50 Hz	240-260 V	250 V	8	245 V / 50 Hz	12
60 HZ	200-217 V	210 V	4	208 V / 60 Hz	4
60 HZ	217-240 V	230 V	6	227 V / 60 Hz	7

3.Locate the transformer: it is on the left end, near the power switch. Move the BROWN and RED transformer wires to the correct terminal. The terminal number is printed in front of the connec- tion tab.

4.Locate the magnetic ballast: it is on the opposite end from the transformer, near the control panel. Move the BROWN ballast wire to the correct terminal. The terminal number is printed in front of the connection tab.

5.Replace the top covers before applying power.
