AC power
Warning! For protection from electric shock, the fixture must be grounded (earthed). The AC mains
supply must be protected against overload with a fuse or circuit breaker and provide ground-fault
(earth-fault) protection.
The MAC III AirFX 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 fuses inside the fixture that
may only be replaced by
service technicians authorized
by Martin™ with Martin™
service documentation for the
MAC III AirFX.
Power connection
Important!
Connect the MAC III AirFX
directly to AC power. Do not
connect it to a dimmer
system; doing so may
damage the fixture.
The MAC III AirFX requires a power input cable with a Neutrik PowerCon NAC3FCA cable connector for AC
mains power input. The cable must meet the requirements listed under "Protection from electric shock" on
page 4.
Martin™ can supply either a suitable 3 m (9.8 ft.) power cable with PowerCon input connector installed or
the PowerCon input connector without a cable (see "Accessories" on page 60).
If you need to install a PowerCon connector on the power cable, see the next section.
