Installation
Mounting
The JS-ICON Series dimmer racks can be mounted to any wall surface capable of supporting
its weight of approximately 66 lbs (30 kg) for each rack. Four 1/4" (6mm) screws or bolts are
required to fasten the rack safely to the wall (see the drawing below for mounting locations and
dimensions). To access the mounting locations, simply remove the lid. The lid is secured by two
(2) #8-32 x 1/2" lid mounting/ground screws with integral star washers located at the top-center
and bottom-center of the lid, as well as four (4) quarter-turn fasteners located in each corner.
Use a #2 Philips screwdriver to remove the two (2) lid mounting/ground screws. To release the
four (4) quarter-turn fasteners, use a athead screwdriver to turn them a quarter-turn counter-
clockwise. Once the lid mounting/ground screws are removed and the fasteners are released,
the lid can be removed. When remounting the lid, it is very important to re-install and tighten the
two (2) mounting/ground screws to ensure ground continuity from the main chassis/enclosure to
the lid. The quarter-turn fasteners are easily locked into place by lining the slot up horizontally,
and pushing it in with a thumb.
WARNING: Risk of electrical shock. Before the power supply is turned on, ensure the lid is
securely fastened to the rack with the two (2) lid mounting/ground screws and four (4) quarterturn fasteners. Never remove the lid when the power supply is turned on.
WARNING: Mount the dimmer racks only as indicated below. Failure to comply may cause
thermal overheating.

Three-Phase to Single-Phase Conversion
JS-ICON™ Series dimmer racks are normally shipped for three-Phase
operation unless otherwise specied at the time of purchase. Please contact
your supplier for a single-phase conversion kit if required. The following steps
will need to be followed to convert the JS-ICON™ dimmer rack from three-
phase to single-phase operation.
1. Remove the three-phase copper bussbars by loosening all of the screws
terminals (use a medium sized #2 Philips or Flathead screwdriver) on
the left-hand side of the circuit breakers.
2. Insert the supplied single-phase copper bussbars, and tighten all of the
circuit breaker screw terminals to 20 IN-LBS (2.26 NM).
3. Reconnect the black #18 AWG wire (underneath) to the Phase A
bussbar.
4. Reconnect the red #18 AWG wire (underneath) to the Phase B bussbar.
5. Tape off or use a marette to isolate the blue #18 AWG wire.
6. Remove two (2) of the phase power terminals (use a 7/16" wrench or
socket) from the old three-phase bussbars, and fasten them to the new
single-phase bussbars. Use the original mounting bolts and tighten to
45-50 IN-LBS (5.0-5.6 NM).
7. Note that the default phase patch will need to be recongured when the
system is powered up. For more information, see “DEFAULTS” menu
item on page 30.
WARNING: Be sure all power connections are tightened to specication
before power supply is turned on.

MADD-24 (Multiple Application Dimmer Driver)
The MADD-24 is the central electronic control system (aka brain) for all JS-ICON™ Series dimmer racks.
The MADD-24 is located on the right-hand side of the dimmer rack, and mounts into card edge connectors
located on the Signal Distribution Board. The MADD-24 can easily be removed by unscrewing two #440 mounting screws (use a small sized #1 Philips screwdriver) located on the top corners, and pulling
it forward using both hands. When re-installing a MADD-24, be sure it is fully seated into the card edge
connectors, and the two mounting screws are screwed in tight.
Located on the MADD-24 is a removable EEPROM memory module. The EEPROM memory module
slides into the PORT1 connector located on the upper center of the board. The EEPROM memory module
is used to backup important conguration settings and may be removed for safe storage. The EEPROM
memory module can also be used for rmware updates. Refer to menu items “EEPROM”, “FW-LOAD”,
“RESTORE” and “BACKUP” on page 27 to 29 for further details.
