MULTISET PRO®- PRE-WIRED DIMMING CABINET MDC20

Installation

and Operation

The MultiSet Pro® is a revolutionary system of advanced digital wallbox dimmers for economical and flexible multi-scene, multi-channel control. MultiSet Pro® provides flexible 13-scene preset dimming control for up to 30 devices, as well as, 12 adjustable fade rates up to one hour that are programmable by scene.

The MultiSet Pro® Pre-Wired Dimmer Cabinet MDC20 facilitates design and installation by combining dimmers and controls into a common enclosure. Each cabinet is shipped assembled, pre-wired, and tested with its dimmers and/or master stations. The cabinet arrives at the job site ready to accept power and load wiring from the installer. This can significantly reduce installation time and potential wiring issues while providing a clean and consistent installation. For design flexibility, the cabinet accommodates several load types and device ratings. To best suit the application, the designer indicates where each device is located within the cabinet.

MultiSet Pro® Pre-Wired Dimmer Cabinet MDC20 is a U.L./c.U.L. listed enclosure designed to hold up to 20 MultiSet Pro® dimmers and masters, which can be configured into one or more individual rooms. Maximum wattage capacity is 20 dimmers at 1000W each (total 20,000 watts) or 10 dimmers at 1920W each (total 19,200 watts). For higher capacity applications, multiple cabinets (MHPWDC20, MDC20, MDC56) may be wired together.

Note: A single MultiSet Pro® System (purple wire network) can accommodate up to 30 MultiSet Pro® dimmers and masters.

When the total number of MultiSet Pro® devices exceeds the 30-device limit, use the dimming cabinet to accommodate one or more [30 devices] MultiSet Pro® Dimming Systems. Blank plates are provided to cover all unused spaces. The dimmer cabinet is surface or recess wall mounted. All dimmers and components are serviceable or removable from the front of the cabinet. The cabinet features a doublehinged, lockable latching cover. The cover is made from heavy gauge steel which prevents tampering of the devices.

The MDC20 Cabinet features air vents to maintain proper air flow through the dimmers. The cabinet shall insure satisfactory operation of the equipment within an ambient temperature range of 0° to 40° C. (No cooling fans are used.)

For applications that require rough in prior to the dimmers being installed, order the MultiSet Pro® Cabinet Enclosure (MDC20ENC) and Cabinet Interior (MDC20INT). (See 87-0573 MDC20 Product Specification Sheet.)

Description

Entrance into the line voltage wiring section is through the double-hinged front cover of the cabinet. Provide a separate neutral connection for all loads (no common neutrals). If normal power is lost, the dimmers will retain their presets and will return to their last state when power is restored.

Note: Each dimmer is fed from an individual circuit breaker. (See Typical Wiring Diagram on page 7.)

Wiring

1. All MultiSet Pro® devices require a neutral connection (no common neutrals). Each circuit-feeding dimmers and dimmed loads require a separate neutral. Shared neutrals will result in undesirable flashing of controlled loads.

2. Use VA dimmers to control incandescent, low-voltage with magnetic transformers, neon, cold cathode, or general inductive loads. When calculating a magnetic low-voltage load, a 25% transformer loss must be factored (i.e. actual lamp wattage plus 25% equals total load).

3. Use Quiet Electronic (QE) Dimmers to control only low-voltage fixtures that have electronic, solid-state transformers, and regular incandescent loads. Not for use with Magnetic Low Voltage fixtures.

4. Use HDF Direct Drive Dimmers to control fluorescent lighting loads at 120V with approved Lightolier® Controls PowerSpec® HDF Electronic Ballasts only, and Lightolier® Controls Dimming Amplifiers.

5. Use Electronic Ballast (EB) Direct Drive Dimmers to control Advance Mark 10® Dimmable Electronic Ballast.

6. MultiSet Pro® Dimmers or Switches may be fed individually or in groups, regardless of phase.

7. MultiSet Pro® Masters draw approximately one watt and may be fed through any circuit. Multiple masters may be interconnected. The total number of dimmers and masters are not to exceed 30. An unlimited number of channel remotes (MSCR) may be used.

8. HDF Dimmers can be connected to a Dimming Amplifier. Please consult interface and amplifier instructions for wiring. Non-dim switches can be connected to MultiSet Pro® relay modules for 277V loads.

9. Line voltage must not be supplied by a GFI breaker.

Note: All wiring should be in accordance with local regulations and the National Electrical Code. All wiring shall enter and exit the cabinet via the provided knock outs at the top or bottom of the cabinet.

2. Terminate 120VAC lines and neutrals to terminal blocks. Do not use common neutrals

3. Connect lighting loads to the load terminal block. Be sure to match proper load with the correct device (refer to device location sticker on front of cabinet).

4. Connect ground to dimming cabinet.

5. Connect network "purple" wire to additional cabinets (when necessary).
