Connecting to an AC mains power source
The MAC Viper Performance power cable can be hard-wired to a building installation circuit or fitted with a
cord cap (mains plug) to allow connection to local AC mains power outlets. If you install a cord cap (mains
plug), 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.
See Figure 7. To apply power to
the MAC Viper Performance,
check that the tilt lock is released,
that the base is held securely, and
that personal safety will not be put
at risk when the lamp strikes and
the fixture moves, then set the
power on/off switch B to I (On).
Check that the mains power on/off
switch B is set to O (Off) before
inserting or removing the power
input connector at the input
socket A, otherwise you may
cause arcing at connector
terminals that can damage them.
Shutting down power
For optimum lamp life, wait for at
least 5 minutes after striking a
discharge lamp before shutting
down the lamp.
It is also good practise to shut down the lamp a few minutes before shutting down power to the fixture. This
gives the fans time to cool the fixture down.
