*Warning: Installation and maintenance of this device should only be performed by qualified, competent personnel that have appropriate training and experience with high voltage and current devices. Failure to follow the instructions / warnings in the Meter Installation Guide can result in permanent damage to the meter, severe injury or death.
This video is purely for demonstrational purposes. When performing this procedure, a qualified person shall wear protective PPE gear rated accordingly for your electrical system.
Before you begin:
1. Turn off all power to the circuit monitor and the equipment in which it is installed. Be aware that the circuit monitor may be connected to a separate power source derived from the equipment in which it is installed.
2. To turn off power to the circuit monitor:
a. Disconnect the metered voltage either by removing the fuses from the potential transformer (PT secondaries) circuits or by turning off the voltage disconnect switch.
b. Short circuit the current transformer (CT) secondaries to remove the metered current.
c. Turn off the control power and any power sources to the auxiliary inputs and outputs.
d. Turn off power to any option cards already installed in the circuit monitor.
e. Always use a properly rated voltage sensing device to confirm that power is off.
