From hardware to software, we tailor solutions to your exact specs. - 1. Verify that the system voltage matches the HV-BC150 rating (1000V DC).
- 2. Ensure all battery connections are properly torqued and insulated.
- 3. Confirm that the mounting surface is flat and capable of supporting the unit weight.
- 4. Prepare communication cables (CAN / RS485) with correct pin assignments.
- 5. Review the user manual for electrical clearance and creepage distance requirements.
- 1. Mount the HV-BC150 using the detachable hanging ears (hole spacing: 465mm × 101.6mm, Φ6.8 slots).
- 2. Connect BAT+ / BAT- to the battery cluster, and PCS+ / PCS- to the inverter.
- 3. Wire the 24V auxiliary power supply and communication cables as per the pinout.
- 4. Enable the circuit breaker (QSB) to energize the system — observe the pre-charge sequence.
- 5.Safety: Always de-energize before servicing. Use insulated tools and wear PPE.
