Wiring
RISK OF ELECTRIC SHOCK OR PERMANENT EQUIPMENT DAMAGE
CT terminals are referenced to the meter’s neutral and may be at elevated voltages:
· Do not contact meter terminals while the unit is connected
· Do not connect or short other circuits to the CT terminals
Failure to follow these instructions may cause injury, death or equipment damage.
WARNING
1. Turn off all power supplying this device and the equipment in which it is
installed before working on the device or equipment.
2. Always use a properly rated voltage sensing device to confirm that all
power is off.
3. Connect the CT output leads to the meter inputs. The white wire is the x1
lead. An arrow points to the load side.
4. Release the clasp on one side of the CT and open it on the hinge.
5. Fit the Rogowski coil around the conductor, bringing the coil ends
together.
6. Lock the coil by turning the ring clockwise as shown in the diagram
