Universal multifunctional dc indicator SIRAX BM1450
Safety instructions
The unobjectionable and hazard-free operation presupposes that the
safety instructions as well as Device Manual, electronically down-
loadable via www.camillebauer.com, have been read and understood.
The installation and commissioning should only be carried out by trained
personnel.
Check the following points before commissioning:
- that the connection wires are not damaged, and that they are not live during
wiring
- that the power flow direction and the phase rotation are correct
- that these product do not have internal fuses
The instrument must be taken out of service if safe operation is no longer pos-
sible (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 instal-
lation check that a labeled switch is installed and that it can easily be reached
by the operators.
The device is maintenance free. Unauthorized repair or alteration of the unit
invalidates the warranty.
Application area
The SIRAX BM1450 compact device is intended for firm installation and to mea-
sure dc voltage, current, frequency, power, energy (active / reactive / apparent),
power factor, phase angle, etc. in low voltage switching facilities. The meter can be
used for up to 4 channels.
Mounting
- Any mounting position is possible
- Devices with display are designed for panel mounting. The necessary panel cu-
tout and the required minimum distances are shown in figure 2. Slide the device
from outside into the cutout and fix it by means of the four mounting clamps.
Electrical connections
A marked and easily accessible current limiting switch has to be
arranged in the vicinity of the device for turning off the power supply.
Fusing should be 10 Amps or less and must be rated for the availab-
le voltage and fault current.
Attention: Danger to life! Ensure that all leads are free of potential
when connecting them!
All voltage measurement inputs must originate at circuit breakers
or fuses rated 1 Amp or less. This does not apply to the neutral
connector. You have to provide a method for manually removing
power from the device, such as a clearly labelled circuit breaker or a
fused disconnect switch.
When using voltage transformers you have to ensure that their
secondary connections never will be short-circuited.
No fuse may be connected upstream of the current measurement
inputs!
When using current transformers their secondary connectors must
be short-circuited during installation and before removing the device.
Never open the secondary circuit under load.

Parameterization
Complete parameterising of all functions of BM1450 is possible via 3 push-but-
tons on site or via communication interfaces Modbus (RS485). The detailed
description of the configuration and parameterization of the device is described in
2
the device manual.
