  • Page 13: Wiring

    Wiring Wiring Electrical connection terminals are located on the top and bottom of the back side of the ITS Test Block. The connection terminals accept ring cable lugs and spade cable lugs. Use the included special phillips cross recessed pan head screws (UNC thread). The screws are magnetic and can be mounted with power screwdrivers (fastening torque 1.2 Nm).
  • Page 14 3. I NSTALLATION ITS functionality requires that the B-SIDE (device side) of the test block must be connected with the device to be tested (e.g. protective relay), and the A-SIDE (system side) must be connected to the electrical system (e.g. CTs, PTs and breakers). Following figures represent the top, back and bottom side labeling of a typical ITS Test Block.

    4 Operation Handling of STP Test Plugs and test probes (smaller plugs for individual circuits) should be done using only the handle and/or insulated plastic parts, since the fingers may be connected to live equipment either via the test block or test equipment. Store the STP Test Plugs and test probes carefully in order to avoid damage to the metallic test fingers.
