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. NOTE • 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. (Unit: mm) Lithium battery: (Unit: mm)
