AC power

Warning! For protection from electric shock, the fixture must be grounded (earthed). The AC mains
supply must be fitted with a fuse or circuit breaker and ground-fault (earth-fault) protection.
Important!Check that the correct fuse is installed before applying power.

Power input and primary fuses

The MAC III Profile features an auto-sensing switch-mode power supply that automatically adapts to
200-240 V (nominal) AC power at 50 or 60 Hz. It is protected by two 16 A slow-blow primary fuses, one for
the live conductor and one for the neutral conductor.
To install fuses:
1. Disconnect the fixture from
AC power.
2. Use a flat-headed
screwdriver to open the
two main fuseholders,
located above the power
on/off switch and mains
input socket.
3. Install one 16 AT fuse in
each fuseholder.
4. Reinstall the fuseholders
before reapplying power.

Power connection

Important! Connect the MAC III Profile
directly to AC power. Do not
connect it to a dimmer
system; doing so may
damage the fixture.
If you install a cord cap (mains plug) on the power cable to allow connection to power outlets, install a
grounding-type (earthed) plug, following the plug manufacturer's instructions. Table 1 shows some possible
mains power 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, first check that the head tilt locks are released and then set the power switch on the base to
the "I" position.
The MAC III Profile is supplied with a power cable with a Neutrik PowerCon NAC3FCA cable connector for
power input. If you replace the power cable, observe the pinout marked on this cable connector. Connect
the terminal marked
live. Replacement power cable must be 3-conductor, rated minimum 20 amp, extra-hard usage. Suitable
cable types include ST, STW, SEO, SEOW and STO.
