2Installation Scenarios
If the system
configuration
exceeds the
maximum
capacity/layer,
install the
modules on
different layers.
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.

3Installation Preparations
Wear gloves during installation.
Never install a module with power on. Ensure that the angle between a module and the line vertical to the ground is within 10degrees.
Do not assemble a lithium battery with an RRU. Do not install a PSU on the left side of an RRU or lithium battery.
The paint on the module exterior should be intact. If paint flakes off, repaint the area to avoid corrosion.
An upstream AC SPD of at least 30 kA is required for the PSU.
When securing a large-pole mounting kit, ensure that the hoops are closely attached to the pole and that there are no sundries between the
hoops and the pole.
When the PSU is assembled with the RRU or lithium battery, ensure that the PSU, RRU, and lithium battery are installed in thesame direction
and that the handles are on the same side.
After unpacking the equipment, you must power it on within 24 hours. When the equipment is maintained, the power-off duration cannot
exceed 24 hours.
If a lithium battery sunshade is configured, install the sunshade on the outer side of the lithium battery after installing the PSU and lithium
battery.

when preparing AC cables.
Multi-core cables should be used as AC and DC power cables; otherwise, water may seep into the waterproof connectors.
Before assembling the waterproof connector, check whether the connection between the cable and terminal is firm and reliable.

1. Check that the mounting kits are securely installed and all screws are tightened.
2. Check that all cables are reliably connected with correct polarity and there is no short circuit.
3. Check whether any screw hole is not installed with a screw. If yes, install a screw in the hole.
6Verifying the Installation
7Power-On Commissioning
1. Measure the PSU input voltage. Ensure that AC input voltage is in the range of 85–300 V AC and the HVDC input voltage is in the range of
90–400 V DC.
2. Check the indicators on the PSUs and lithium batteries. Ensure that the green indicators are blinking slowly and red indicators are off.
3. Measure the DC output voltage at each load port. Ensure that the voltage is in the range of–42 V DC to –58 V DC.
4. Observe the power system for about 15 minutes. If no alarm indicator is on, the system is running properly.
