Installation and connection – CAN-EZ3A energy meter

The CAN-EZ3A is installed in a meter box in accordance with local regulations. It can be snapped on
to a top-hat rail (DIN support rail TS35 to EN 50022).
The 2-pole connectors of the current transformers are connected to the CAN-EZ3A and folded over
the cores. When doing this, pay attention to the correct assignment (I1 - I3) in accordance with the
voltage connections and a positive phase sequence.

For voltage measuring, the required wires are connected to the voltage terminals in the CAN-EZ3A.
The connection of sensors, and CAN and DL buses is carried out using the supplied connectors

Power supply

The CAN-EZ3A is supplied with power via the voltage measuring connection 

U1

 (first phase).

Time stamp

The CAN-EZ3A has a real time clock and, as node 1 in the CAN bus network, can therefore transmit 
the time and date to other devices.

Caution

 The surfaces of the current transformer ferrite cores must be completely clean. Even tiny

dust particles or greasy films can severely affect the measuring result. These surfaces must there-
fore be cleaned with a clean, lint-free cloth or clean fingers before closing.
