INSTRUCTIONS1. Run all current carrying conductors through detectorwindow.A. Use an auxiliary CT if conductors do not fit. ConsultFactory for CT selection.2. Mount the detector to a surface if needed.3. Connect output & power wiring.A. Use 30-10 AWG copper conductors rated 75°Cminimum. Tighten to 5-7 inch-pounds.B. Make sure power and load matches those shown onthe sensor’s label.4. Test.A. Pressing the “TEST” button tests the detectorsinternal circuits.

Keep in mindthat the best way to reduce noise in a system is to suppressit at its source.1. Keep the detector power isolated from noisy circuits.2. Do not power the detector with the same circuit thatswitches contactors or other high current, inductive loads.Good design practice and code require that all AC powersystems be grounded. AG Series detectors are designed towork on grounded AC power systems. They may not operateproperly on ungrounded systems.For products intended for the EU market, the following is applicableto the CE compliance of the product:The sensor may comply with EN 61010-1 CAT III 600 V max line-to-neutral measurement category. If insulated cable is used for the primarycircuit, the voltage rating of the measurement category can be improvedaccording to the characteristics given by the cable manufacturer. A fuserated 5 A max shall be placed in series with the main input power termi-nal. Use twisted pair for output connection.De-energize power before changing setpoint jumper position.Warning! Risk of DangerSafe operation can only be guaranteed if the sensor is used for the purpose itwas designed for and within limits of the technical specifications. When thissymbol is used, it means you must consult all documentation to understandthe nature of potential hazards and the action required to avoid them.Warning! Risk of ShockWhen operating the senor certain parts may carry hazardous live voltage(e.g. primary conductors, power supply). The sensor should not be put intooperation if the installation is not complete.AG 1 - SDT1 - 120 - ENE - 005 - NOUTPUT TYPE:SDT1 - SPDT Relay (Form C)1 A @ 120 VAC, 2 A @ 30 VDCPOWER SUPPLY:24U - 24 VAC/VDC120 - 120 VACSETPOINT RANGE:1 - 5-100 mA, Adjustable2 - 80-950 mA, Adjustable3 - Tri-Set, 5, 10 & 30 mA, Jumper SelectAG Series Ground Fault DetectorOPTIONS:ENE - Normally EnergizedDEN - Normally De-energizedSETPOINT:005 to 950 - Factory AdjustedSetpoint in mA (spec-ify when ordering)TR3 - Tri-Set, 5, 10 & 30 mA,Jumper SelectNOISE IMMUNITY:N - Noise ImmunityNone (Blank)3511 Charter Park Drive, San Jose, CA 95136Phone: 800-959-4014 oe 408-871-7510Fax: 408-871-7515sales@nktechnologies.com, www.nktechnologies.com |
