A21 120V IGBT Dimmer Module
Installation & Operation Guide
Description
The A21 IGBT Dimmer Modules offer high performance dimming of various load
types, while operating at increased efficiency and reducing lamp noise on incandescent lamp types. IGBT Dimming Technology provides precise control over inrush
current without the use of chokes, and resists damage from short circuits.
All A21 Dimmer Modules have identical mounting dimensions, allowing them to
be easily swapped within any of the A21 Lighting Control Panels. (Use caution to
ensure that quad dimmer modules are not installed into module spaces wired for
dual dimmer modules.)
WARNING: Installing the module with power applied to the cabinet may
expose you to dangerous voltage and damage the device. Remove power
before installing. A qualified electrician should perform this installation.
Installation
Any combination of A21 dimming and relay modules may be installed in the Lighting Control Panel. Blank covers MUST be installed in any unused spaces. Pull the
jumper (shorting plugs) before installing.
To install modules:
Step 1. Unpack module and recycle or properly discard packaging materials. (Be
sure to keep this instruction sheet for future use.) Inspect dimming
module for signs of damage during transit.
Step 2. Disconnect main power to A21 Lighting Control Panel.
Step 3. Open dimmer module side of panel front cover.

DETAIL
Figure 1: Installing Modules and Blank Covers
Step 4. If present, remove blank cover from location where module is to be
installed (Figure 1). When possible, lower modules should be installed
first.
Step 5. Remove shorting plugs from the load terminal block. (The shorting plug
is the red tab protruding from the green load terminal block.) To remove,
grasp the shorting plug and gently pull. Note: The dimmer module will
not operate properly if the shorting plug is left in circuit.
Step 6. Gently insert module into lighting control panel, heatsink first. Secure
module using four screws (provided). Dimmer Module should be
installed with the heatsink facing away from you.

Operation
74170: 1500VA
A21 Dimmer Modules are equipped with a "Focus Button" on each circuit
(Figure 1). Tapping the focus button quickly will turn the circuit on to full, tapping
it quickly again will turn the circuit off. Pressing and holding the focus button will
ramp the dimmer up to full intensity. If the focus button is released before reaching
full intensity, the dimmer will stop at that relative output.
