AC power 9
AC POWER
WARNING! For protection from electric shock, the fixture must be grounded (earthed). The AC mains
supply shall be fitted with a fuse or circuit breaker and ground-fault protection.
Important! Verify the power supply settings before applying power.
The chapter describes:
• Installing fuses
• Power supply adjustments for the various MAC 2000 Performance II models
• Connection to a power supply (see page 9)
• The reduced power function (see page 10)
Fuses
The MAC 2000 Performance II comes with two:
• 20 AT (time delay) main fuses for use with AC supplies of 100 - 120 volts.
• 15 A main fuses for use with AC supplies of 200 - 250 volts.
Install the appropriate fuses in the holders near the power switch.
Power supply adjustments
The MAC 2000 Performance II (identified as such by the label on the base of the product) comes with an
electronic ballast and an auto-sensing, auto-ranging switch-mode power supply. Manual adjustments to the
transformer or ballast are not necessary as the MAC 2000 Performance II automatically adapts to the mains
voltage and frequency.
Note that MAC 2000 fixtures from S/N 4006756001 to S/N 4017886000 manufactured from mid-2003 to
mid-2004 contained a power supply unit that needed to be switched to match AC power voltages below 130
V or above 200 V.
Power connection
Important! Connect the MAC 2000 Performance II 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.
