DMX-4 User Manual (Rev. 2)
The DMX-4 has an auto-ranging power supply and it can work with an input voltage
range of 100–240 VAC, 50/60 Hz.
To determine the product's power requirements (circuit breaker, power outlet, and
wiring), use the current value listed on the label affixed to the product's back panel, or
refer to the product's specifications chart. The listed current rating indicates the
product's average current draw under normal conditions.
Always connect the product to a protected circuit (circuit breaker or fuse). Make
sure the product has an appropriate electrical ground to avoid the risk of
electrocution or fire.
Never connect the product to a rheostat (variable resistor) or dimmer circuit, even
if the rheostat or dimmer channel serves only as a 0–100% switch.
Disconnect the product from power before replacing the fuse.
1.
Disconnect the product from power.
2.
With a #2 Phillips-head screwdriver, unscrew the fuse holder
cap from the housing.
3.
Remove the blown fuse.
4.
Replace with a fuse of the same type and rating.
5.
Screw the fuse holder cap back in place and reconnect
power.
Always replace a blown fuse with another of the same type and rating.
Dimmer/switch packs are primarily intended for lamp-based PAR cans. Connecting a
fixture equipped with an electronic (switching) power supply to a dimmer/switch pack
may damage the fixture or make it work erratically.
The improved DMX-4's design now allows you to switch on and off loads equipped with
electronic power supplies, such as LED-based luminaries or laser fixtures. However, the
DMX-4 must be in Switch mode before connecting loads of this type to it. Please see the
instructions on how to set the DMX-4 in Switch mode below.
Always make sure that the DMX-4 is in Switch mode before connecting a load
equipped with an electronic power supply to it. Doing otherwise could damage the
load.
The DMX-4 is optimized to also operate with LED-based products.
