Installation and Operation InstructionsPart # A/CS2, A/CSX2A/SCS2, A/SCS2-L, A/SCSX2AUTOMATION COMPONENTS, INC Version : 3.0Page 1 of 3 I0000787Please Read Instructions Carefully Before Installation!WARNING:• This product is not intended to be used for Life or Safety applications.• This product is not intended for use in any hazardous or classified locations.• The A/CS2 and A/SCS2 Series Current Switches must be used on Insulated Conductors Only!HIGH VOLTAGE:• Disconnect and lock out all power sources before installation as severe injury or death may result from electricalshock due to contact with high voltage wires.• Never rely on the Red LED to determine whether power is present at the current switch. At very low monitoredinput currents the Red LED may not light to indicate the current is above the trip point. InstallationMake sure that all installations are in compliance with all national and local electrical codes. Only qualified individuals that arefamiliar with codes, standards, and proper safety procedures for high-voltage installations should attempt installation. The currentswitches will not require external power, since the power for the current switch is induced from the conductor being monitored.The current switch may be mounted in any position using the two #8 x 3/4” Tek screws and the mounting holes in the base, orsnapped directly on to the 35mm DIN rail (See Figure 1). Leave a minimum distance of 1” (3 cm) between the current switch andany other magnetic devices such as contactors and transformers.Figure 1: Sensor Placed on Rail Latch Operation for A/SCS2 SeriesPress down on the side tab and swing the top of the unit up to open the split core current switch as shown in Figure 2. Press downfirmly on the cover to close the current switch. An audible “click” will be heard as the tab slides over the tongue on the base.CAUTION: Mating surfaces of the magnetic core are exposed when the sensor is open. Electrical contact grease, present onthe cores to prevent corrosion, can capture grit and dirt if care is not exercised. Operation can be impaired if anything preventsgood contact between pole pieces. Visually check the mating parts of the core before closing the current sensor.Figure 2: Opening A/SCS2 Series!!
