INSTALLATION AND OPERATION The SE-100T is a ground-fault-relay tester for 5-A and 15-A resistance-grounded systems. The SE-100T has an output ammeter, a test pushbutton, low (LO) and high (HI) outputs, and a remote-test input (RMT). Test currents of 0.65 A (LO) or 2.75 A (HI) are provided for injection in window-type current sensors. Multiple CT wraps can provide a window current that is a multiple of the ammeter reading. SE-100T outline and mounting details are shown in Fig. 1. Typical connections are shown in Fig. 2. Connect supply voltage to L1 and L2. Connect chassis bonding terminal to ground. Loop a test wire through the windows of the ground-fault CT's. Connect one end of the test wire to terminal C and the other end to terminal LO or terminal HI for a test current of 0.65 or 2.75 A. For remote operation, connect a normally open contact between terminals L1 and RMT. To test ground-faultrelay operation, press the test pushbutton for an interval that is longer than the time-delay setting of the relay or relays being tested. If precise current adjustment or a timed output is required, use the SE-400 ground-faultrelay test unit. 109.0 (4.29) 100.0 (3.93) 77.8 (3.06) 88.9 (3.50) C H I L O RMT L 1 OUTPUT L2 USE HI FOR 15-A SYSTEMS USE LO FOR 5-A SYSTEMS AC AMPERES 150.0 3 (5.90) 2 139.7 1 (5.50) 0 TEST SE-100T GF TESTER NOTES: 4.8 (0.19) DIA 1.
