3. Device overview
3.1 Brief description
The universal 4-channel DC meter SIRAX BM1450 can be used for monitoring and control in DC systems. These meters measure a variety of
electrical parameters such as DC voltage, current, power, energy and electrical charge. They support bidirectional voltage and current measure-
ment, 1-channel voltage input, 4-channel current input and 4 relay outputs. The large 4-line, 8-digit LED display provides easy reading of data
directly on the device front. The configuration can be done on site using three pushbuttons or via Modbus RTU.

4. Installation and commissioning
The installation and commissioning should only be carried out by trained personnel. Check the following points before commissio-
ning:
- that the limits of the operating temperature are not exceeded:
–10 … +55° C
- that the maximum values for all the connections are not exceeded, see „Technical data“ section,
- that the connection wires are not damaged, and that they are not live during wiring,
- the polarity of the DC supply is correct.
The instrument must be taken out of service if safe operation is no longer possible (e.g. visible damage). In this case, all the
connections must be switched off. The instrument must be returned to the factory or to an authorized service dealer.
It is forbidden to open the housing and to make modifications to the instrument. The instrument is not equipped with an integrated
circuit breaker. During installation check that a labeled switch is installed and that it can easily be reached by the operators.
Unauthorized repair or alteration of the unit invalidates the warranty.
The national provisions have to be observed in the installation and material selection of electric lines!
