Tap selection must be based on the maximum load wattage (sum of the wattage of all lights connected to the MRIDC Dimmer output and select the tap rated slightly greater than the wattage). A minimum 30% load (of tap level) is required at all times. Improper tap selection may cause damage and will void the manufacturer warranty. -
Page 15: Start Up And Operation
START UP AND OPERATION Initial Power-up After the installation is complete, move the dimmer slide switch to the lowest (down) position. Turn on the Main input circuit breaker. Verify the Dimmer, on/off switch is in the “ON” position and slide the dimmer knob to a suitable illumination (setting). -
Page 16: Preventive Maintenance
PERSONNEL ONLY. Maintenance WARNING: Make sure the power is turned OFF at the source to the MRIDC Dimmer before cleaning. Due to the solid-state nature and natural convection cooling of the MRIDC Dimmer design, maintenance is generally not required. For dusty environments, it would be desirable to open the main cover and blow out the interior using clean dry compressed air limited to 60 psi. -
