120V/277V Relay Module Models: 74178 / 74179 / 74195 / 74196 / 74273 / 74293 For use with the following A21 120V/277V Lighting Control Panels: A21 3-Space Panel, A21 6-Space Panel, A21 9-Space Panel A21 120V/277V Relay Module Installation & Operation Guide Description The A21 Relay Modules offer economical and reliable switching of non-dim loads including lighting, signs, and motors. The modules utilize rugged relays and feature dual-color status indicators, and focus buttons for manual operation and testing. Screw (4) All A21 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.) Blank Cover 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. (74181) Screw (4) 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. Focus Button & Status LEDs Relay Module Load Terminal Block Terminal To install modules: NOTE: The A21 9-Module Panel is used to illustrate the installation. However, module installation is identical for all Lighting Control Panel models. 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 module side of panel front cover. 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 module will not operate properly if the shorting plug is left in circuit. Step 6. Gently insert module into Lighting Control Panel with relays facing you. Secure module using four screws (provided). Note: The connectors of 277VAC A21 modules are keyed, preventing the insertion of modules into panels of the incorrect voltage. Do not force modules into slots. Step 7. Close panel front cover. Operation A21 Relay 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.
