Installation Scenarios
NOTE
There are two pole-mounting scenarios. In the large pole scenario, the pole diameter is 114 mm to 400 mm. In the small pole scenario, the pole
diameter is 60 mm to 114 mm. Select an appropriate pole based on site requirements. The following uses the small pole scenario as an
example.
•
If multiple PSUs are configured, they can be cascaded by connecting BAT and LOAD ports or by interconnecting LOAD ports. It is
recommended that DC loads be equally distributed on the PSUs.
•
This section uses a maximum of two lithium batteries as an example.
Lithium
DBU20B-N12A3 (≈ 20 kg)
battery:
DBU50B-N12A1 (≈ 26 kg)
(Unit: mm)
Meaning
The PSU has no power input (no AC input and no battery input)
Start / Self-check / Load (instantaneous status during startup or upgrade)
The PSU is not communicating with the host properly
The PSU is proper
The PSU is faulty: Rectifier Fault/Monitoring Address Conflict/Monitoring Unit Fault
An alarm that can be cleared is generated on the PSU: Rectifier Protection/Power off/
Communication Failure/Rectifier Power Failure/Parallel Fail/AC Overvoltage/AC Undervoltage
Meaning
The lithium battery has no power input or is faulty
Board startup / self-check / loading / activation / board power-on when no software is loaded
The lithium battery fails to communicate with monitoring equipment
The lithium battery is proper
The lithium battery has alarms that cannot be cleared: Board Hardware Fault/Heater
Fault/Electrochemical cell fault/Duplicate address
The lithium battery has alarms that can be cleared: Discharge Overcurrent Protection/Charge
Overcurrent Protection/High Temperature protection/Low Temperature Protection/Abnormal
shutdown/Charge Overcurrent Protection/Discharge Overcurrent Protection
