Frequently Asked Questions - SIRAX BT7300 Camille Bauer
How do I configure the SIRAX BT7300 for my system?
Configuration is done via the front panel buttons or through the RS485 Modbus interface using the free Camille Bauer software. The device supports configuration of PT/CT ratios, wiring modes (3-phase 4-wire, 3-phase 3-wire, etc.), and communication parameters.
Can the SIRAX BT7300 measure harmonics?
Yes, it measures individual harmonics up to the 63rd order for both voltage and current. Total Harmonic Distortion (THD) is also displayed.
What is the accuracy of the energy measurement?
The device complies with IEC 62053-22 Class 0.5S for active energy, meaning the error is within ±0.5% at rated conditions.
Does the SIRAX BT7300 require an external power supply?
No, it is self-powered from the measured voltage inputs (85-265 V AC/DC). No auxiliary supply is needed.
How do I connect the RS485 communication?
Use a twisted-pair cable with proper termination. Connect A(+) and B(-) terminals to the Modbus network. Set the device address and baud rate via the setup menu.
What is the maximum cable length for voltage inputs?
For accuracy, keep the input wiring as short as possible, typically up to 100 meters with proper shielding. Use appropriate wire gauge (min 1.5 mm²) to minimize voltage drop.
Can I use the SIRAX BT7300 for both 50 Hz and 60 Hz systems?
Yes, it automatically adapts to frequencies from 45 to 65 Hz, making it suitable for both 50 Hz and 60 Hz grids.
How do I reset the energy counters?
Partial and total energy counters can be reset via the front panel menu: navigate to Energy > Reset, then confirm. Alternatively, a reset command can be sent via Modbus.
Is the SIRAX BT7300 suitable for outdoor installation?
The front panel is rated IP54, protecting against dust and splashes. For outdoor use, it must be installed in a weatherproof enclosure to protect the rear terminals (IP20).
What spare parts are available for the SIRAX BT7300?
Spare parts include communication modules, terminal covers, and mounting brackets. For internal repairs, contact Camille Bauer authorized service centers. The device firmware can be updated via the Modbus port.
