Product description

The DMX8DIM is an 8 channel, 250 Watt dimmer. It is fed by a single 120VAC 20A
branch circuit. Each output is protected by a self-resetting poly-fuse. Each of the
dimmers can be separately controlled using a typical DMX512-based lighting controller.
The DMX8DIM is housed in a standard NEMA1 electrical enclosure. Knockouts are
provided on the top and bottom of the enclosure for easy installation. Cables may enter
the sides of the enclosure by using standard chassis punches.

Safety warnings

• The DMX8DIM should only be installed by qualified personnel in accordance with
local electrical codes.

• There are no user serviceable parts in the DMX8DIM. Servicing should be
referred to qualified service personnel.

• Do not operate the DMX8DIM without the cover installed.

• Turn off all power to the DMX8DIM before installing. Do not attempt to wire or
install any part of the DMX8DIM with the power on.

Environmental

Operating temperature: 0-40º C
Operating humidity: 10-90% non-condensing
Indoor use only

Electrical ratings

Input: 120VAC, 60Hz, 20A
Output: 8 outputs, 120VAC, 250W each. Self-resetting protection on each output.

Certification

The DMX8DIM is ETL Listed under safety Standard UL 508.

Mounting

The DMX8DIM can be mounted on any stable surface in compliance with local electrical
codes. To mount the DMX8DIM:

• Remove the cover by loosening the front panel screws

• Select the desired mounting location

• Locate the mounting holes using the DMX8DIM as a guide

• Secure the DMX8DIM to the surface using appropriate fasteners

• After all wiring is complete and switches have been configured (see below), install
the cover and secure it in place.

General installation notes

• If enclosure knock-outs are used or if holes are punched in the enclosure for wire
entries, the holes must have appropriate bushings or conduit fittings installed to
protect the wires from cuts and abrasion.

• Safety grounding must be maintained through this product. Metallic conduit may
be used for grounding if it is appropriately bonded to the enclosure. The ground
terminal on the line input and all output terminals may be used for grounding
conductors. All such terminals are internally bonded to the enclosure.

Power input (line) wiring

Supply the DMX8DIM with a protected branch circuit of no more than 20A. The power
input terminals on the DMX8DIM are rated for #12AWG copper wire (maximum). The
torque rating for the terminals is 4.51 IN/LB.

Input power wiring must enter the enclosure and route directly to the input power
terminals without crossing over the circuit board or any control wiring.

Line input terminal

Power output (load) wiring

Each output can supply a 250W (maximum) 120VAC load. The output terminals are
rated for #12AWG copper wire (maximum). The torque rating for the terminals is 4.51
IN/LB.

Load wiring must enter the enclosure and route directly to the input power terminals
without crossing over the circuit board or any control wiring.
