Installation
1. Disconnect power prior to the installation. Use a properly rated voltage sensing device to ensure power is off.
2. Install the meter onto standard DIN rail as shown.
Click!
3. Wire the meter (see the Wiring section).
4. Reconnect power to the meter.
5. Configure the meter (see the Configuration section).

CT Wiring
Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the operator. Use fuses/circuit
breakers that are rated for the installation voltage and sized for the available fault current. A fuse for neutral is required if the
source neutral is not grounded.
