Technical Specifications
- Dimensions: 260 mm x 175 mm x 85 mm
- Weight: 2.2 kg
- Country of Origin: Norway
Applications
- Fire Detection and Alarm Systems
- Industrial Control Panels
- Emergency Lighting Systems
- Building Management Infrastructure
Usage Instructions
- Verify the input voltage matches the rated specifications before powering on.
- Ensure the device is installed in a clean, dry, and non-corrosive environment.
- Periodically check the output voltage levels using a multimeter to confirm system stability.
- Do not exceed the maximum rated load to prevent thermal overload and potential shutdown.
Mechanical Installation Requirements
- Fixing Method: Secure the unit to a standard mounting plate using M5 screws at all four corner mounting holes.
- Space Clearance: Maintain a minimum clearance of 50 mm on all sides to allow for natural air circulation.
- Heat Dissipation: Ensure the ambient operating temperature does not exceed 50°C; do not mount the unit directly above other heat-generating components.
Electrical Wiring Guide
- Terminal Definitions: * L (Live), N (Neutral), PE (Protective Earth) for AC Input.
- +DC, -DC for Output terminals.
- Wire Gauge: Use a minimum of 1.5 mm² (16 AWG) copper wire for AC input and 2.5 mm² (14 AWG) for DC output to minimize voltage drop.
- Grounding Norms: The PE terminal must be connected to a dedicated industrial earth point using a multi-strand yellow/green wire for effective surge protection.
Communication Configuration
- IP Address: Access the embedded web interface via the default static IP: 192.168.1.10.
- Station ID: Set via the rotary switches on the front panel; valid range is 01-99.
- Baud Rate: Configurable via software; default is set to 9600 bps for stable RS-485 communication.
Frequently Asked Questions (Q&A)
- Q: Why is the fault LED flashing?
- A: This indicates either an output overvoltage condition or a short circuit in the downstream load. Please check your wiring.
- Q: Can this unit be used in parallel?
- A: No, the BSS-103A is not designed for parallel redundancy.
- Q: How often should I perform maintenance?
- A: An annual inspection of terminal tightness and dust removal from the casing vents is recommended.
