EN / CZone® Meter Interface (MI) User & Installation Manual
AC CONNECTIONS
AC connection and protection must be done in accordance with local standards. Do not work on the Meter
Interface or system if it is still connected to a power source. Only allow changes in your electrical system
to
be carried out by qualified electricians. All AC connections are made on the 6Way connector.
•
Connect voltage inputs from AC voltage transformer to MI, inputs 2, 4 and 5.
•
Connect current inputs from each current transformer to MI, inputs 1 and 3.
•
Connect transformer common to input 6 from the Voltage Transformer.
•
Ensure the potted end of the current transformer is facing the line direction. Part # CT-10-3

Ensure voltage inputs are wired from the voltage transformer
and not directly from the AC power source. Part # AC-VSEN-4
Note: Current Input 1 and Voltage Input 1 are paired inputs, as are Current Input 2 and
Voltage Input 2. For correct metering these must be matched to same supply source.
