PSU load cables and AC input cables should be prepared onsite. DC load cables are used as an example here. Refer to this proc edure
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.

As shown in the left figures, when
the narrow edge size of channel
steel is less than 40 mm, only
installation methods a and b are
supported.
When channel or angle steel is
used for installation, each layer
supports a maximum of 1 PSU + 1
lithium battery or 2 PSUs. Refer to
the procedure for flush mounting
on a small pole.
