Installation
The product is mounted on a DIN-rail. The clip on the bottom is used to attach and detach the product from the DIN-rail. For safety reasons, a DIN-rail enclosure must cover all terminals.
Caution
CMeX10 Series handles from 32 up to 256 slaves, be sure to use the correct model in your application. Overloading the bus will turn the ERR LED on and turn off the M-Bus bus.
Note
All connected M-Bus slave devices must have unique primary or secondary M-Bus addresses depending on addressing mode used.
M-Bus is a multi-drop 2-wire bus, with no polarity.
-
Use a cable with an area of 0.25-1.5 mm2, e.g. a standard telephone cable (EKKX 2x2x0.5).
-
Connect the wiring to the screw connector or the push wire connector.
By using the IR interface, CMe2100 can communicate with Elvaco M-Bus Masters and Wireless M-Bus Receivers (CMeX Series) as well as ABB electricity meters without using any cables. Mount the CMe2100 next to the other device, with the IR interfaces of the two products facing each other. Before attempting to use the IR interface, make sure to remove the IR shield.
Use the RS232 interface to use the CMeX10S, CMeX11S, CMeX12S, and CMeX13S as an M-Bus master from RS232 to M-Bus 2-wire interface.
