CEL LED obstacle lights cabling and installation principles are similar to those of conventional obstacle lights, the only exception being the correct polarity required by DC feed. Terminal box include screw terminals and overvoltage protectors. All connection alternatives can be protected with a 6A or 10A fuse or with a circuit breaker (C curve). Installation specifications - Cable gland for lamp: M20, 8-13mm cable - Cable gland for IN T: M25, 11-17mm cable - Wire diameter: max. 6mm2 - Recommended cable: 3 x 1.5mm2, 3 x 2.5mm2 5 x 1.5mm2 or 5 x 2.5 29 Mar 2016 mm2 cable cable cable Over voltage...
