Installation and connection
The CAN-EZ3 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-EZ3 and folded over the
cores. When doing this, pay attention to the correct assignment (I1 - I3) in accordance with the volt -
age connections and a positive phase sequence.
For voltage measuring, the required wires are connected to the voltage terminals in the CAN-EZ3.
The connection of sensors, and CAN and DL buses is carried out using the supplied connectors
Power supply
The CAN-EZ3 is supplied with power via the voltage measuring connection U1 (first phase).
Time stamp
The CAN-EZ3 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.
