Only qualified individuals that arefamiliar with codes, standards, and proper safety procedures for high-voltage installations should attempt installation. Thecurrent sensor is a 2-wire Loop Powered device that requires a regulated +12 to 30VDC external power source.The A/SCTA Series Analog Current Sensors should be used on Insulated Conductors Only! The current sensors may bemounted in any position using the (2) #8 x 3/4” Tek screws and the mounting holes in the base or snapped directly on to the 35mmDIN rail (See Figures 1 & 2 below). Leave a minimum distance of 1” (3 cm) between the current sensor and any other magneticdevices such as contactors and transformers.3XUSCLISTEDIND.
