DMC4 Installation Instructions Rev 02
1.
After removing both front covers and the required knockouts for the power supply, networking cable and lighting group
channels, mount the unit in its desired location. Once secured, the DMC4 unit is ready for the internal modules to be
mounted.
2.
Mount the communication module below the high-voltage barrier of the DMC4. Refer to the communications module
installation instructions for more details before proceeding.
3.
Mount the DSM4-XX power supply module in the middle of the DMC4. Refer to the power supply module installation
instructions for more detail before proceeding.
4.
Mount the control modules in the remaining module spaces. Any control module can be mounted in any location and
any module location can be left empty, provided the corresponding wiring loom connectors are safely insulated (see
below). Refer to the control module installation instructions for more details.
5.
Connect the supplied wiring loom to the DMC4 as shown. Use only the loom supplied with the unit, and do not break or
modify the loom in any way. Make sure the labels on the loom correspond to the wiring on each module. For modules
requiring termination, remove the black insulating caps from the loom before terminating to the load and supply
modules.
For any module location that is not populated or does not require termination, the corresponding
insulating caps (or mains-rated isolating electrical terminators) must remain in place on the loom.
Terminate the
correctly rated supply to each module but do not energize.
6.
Check and retighten all terminals. Remove the knockout detail on the front cover as required. Replace the top and
bottom cover plates, and make sure all screws are tightened securely. Stick the labels provided with the modules on the
cover plate to indicate which module is installed in each location. If an uncovered knockout is not used, cover it with a
suitable blanking plate.
7.
The unit is now ready to be energized. If required, the bottom communication module cover can be removed when
energized to access the override key matrix.
