The supplied combined power and control cord (roughly 9 feet, 2.7m in length and with
bare wire tails) attaches to the rear of the fixture via an IP66-rated composite connector. If
you need to connect Unity to an Outdoor Link System configuration, use an optional OLS
Link Cable (see pages 7 and 23) in place of the included bare wire feed cable.
The standard cord color designations are as follows:
POWER CO N NEC TION
Note: Do not connect or disconnect the cord when
power is applied.
The power and control cord is attached at the rear
panel via an IP66-rated composite connector. Align
and push the plug in to connect. Be sure to confirm
the connection is made by gently pulling the
connector to ensure it has locked into place.
To disconnect: Turn the blue collar clockwise.
POWER REQUIREMEN TS
The power requirements are as follows:
• Voltage:
100-277VAC 50/60Hz

recommends taking proper precautions for external surge protection, as
control and power electronics can be damaged by major events.
I N-RUS H CU RRE NT
Although LED fixtures are low power devices compared to their incandescent equivalents,
their power supplies exhibit a trait known as 'in-rush current' when they are first powered
on. This is caused by the various components within the switching power supplies topping
themselves up with power. The in-rush current period lasts only milliseconds and does not
cause any effect when a handful of units are powered on at the exact same time. However,
if many fixtures are linked to the same power input, they will momentarily pull a current that
may greatly exceed their normal operating level. This may affect over-current trips when
power is applied. For this reason it is advisable to limit the number of fixtures on any one
power input.
