Installation instructions

Warning: Please use professional and appropriate protective equipment to prevent electric shock and ensure safety.

Installation steps

Step1. Before installing, ensure that the circuit is in the state of power failure, or live installation operation, professional personnel are required.

Step 2. Open the protective cover of current transformer, connect the wire with the terminal output of the current
transformer and connect it to the port of the measuring equipment, and ensure the circuit is closed. See Figure 1.

Step 3. Open the transformer latch and prepare for installation. See Figure 2.

Step 4. Place the cable inside the hole of current transformer. Ensure that the current direction of the cable is consistent with the arrow on the current transformer. Lock the latch again, and fix the cable with the nylon ties to hook both ends of the transformer to prevent sliding. See Figure 3.
