POWER AND CONTROL WIRING

The combined power and control cord (roughly six feet, 1.8m in length) enters the casing
via a water-tight gland at the rear of the fixture. The cord can be supplied either with bare
tails or an Outdoor Linking System connector (see page 15).
For models with bare tails, the power cord color designations are as follows:

POWER
The power requirements are as follows:
• Voltage:
100-277VAC 50/60Hz
• Power:
40 or 42W steady state (according to model)
Note: Acclaim recommends taking proper precautions for external surge protection, as control
and power electronics can be damaged by major events.
The DMX header cable connected to the feed cable should be suited for RS-485 data
transmission and have a characteristic impedance of 120 Ohms, such as Belden 9842 or
equivalent.
IN-RUSH CURRENT
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.
