191 TouchDIM A commercial wall switch is enough to dim lamps/control gears with TouchDIM function using a 4-wire building in- stallation. Lamps are turned on and off by pressing the button briefly; pressing and holding the button dims the lights. Depending on the manufacturer and the control gear, up to four lamps/control gears can be controlled using buttons, provided that the total cable length of all control sections does not exceed 25 metres. Forward/reverse LED phase control (TRIAC) Many RIBAG LED lamps are nowdimmable using the exist- ing house installation with three wires. A traditional wall dimmer (button or rotary LED phase dimmer) is used to control them. Phase dimmers can also be used to dim our voltage LED lamps (AC). Note: The minimum load of the wall dimmer must be less than the power consumption of the lamps used. In rare cases,light fluctuationsmay occur with LED lamps powered by mains voltage (AC) due to grid disturbances (ripple control signals of energy suppliers, faulty house- hold appliances etc.). These disruptions do not indicate a defect with the lamp. Our customer service will be happy to assist with disruption analysis. Bluetooth and additional dimming and control methods Bluetooth and additional dimming and control methods as well as a comprehensive overviewof compatibility with our lamps, control gears, and recommended dimmers can be found at www.ribag.com/dim. R,C L PE N L PE N PUSH Cable lengths for lamps with external control gears The maximum cable lengths between LED lamps and control gears can be taken from this table. In general: The higher the power, the larger the cable cross-section must be. Maximumcable lengths between lamp(s) and control gear in relation to cable cross-section and power input: 0,75 mm 2 1,0 mm 2 1,5 mm 2  10 W 16 m 33 m 49 m  15 W 11 m 22 m 33 m  20 W  8 m 15 m 23 m  25 W  6 m 12 m 18 m A maximum voltage drop of 2% is allowed on the cables. For EMC reasons, the cable between the dimmer and the LED lamp may not be longer than 10m. Photometric tolerances The lumen and wattage figures are design values and ini- tially subject to a tolerance of +/–10%.Tolerance of colour temperature +/–150K. Unless specified otherwise, the values apply to an ambient temperature of 25°C.
