CurrentWatch™ ECSD Series Current Switches
DC Current Switches with Jumper Selectable
Current Ranges
Wiring Diagrams
Connect control or monitoring wires to the sensor. Use 12-22 AWG
copper wire and tighten terminals to 4.5 in.-lbs / 0.51 N·m maximum
torque. Be sure the output load does not exceed the switch rating.
CAUTION!
INCANDESCENT LAMPS CAN HAVE "COLD FILAMENT INRUSH" CURRENT OF
UP TO TEN TIMES THEIR RATED AMPERAGE. USE CAUTION WHEN SWITCHING
LAMP LOADS CONNECTED TO THE SOLID-STATE OUTPUT.
CAUTION!
DO NOT DISCONNECT OUTPUT TERMINALS UNDER LOAD.
