The following problems need to be avoided when installing the small power distribution unit:

Improper location selection: The small power distribution unit should be installed in a well-ventilated, dry place, away from direct sunlight and humid environments, to prevent electrical components from getting damp or overheating.

Insufficient installation: The small power distribution unit should be firmly fixed on the wall to avoid looseness or tilting to ensure safe use and easy maintenance.

Cable layout is messy: Cables should be laid out rationally to avoid crossovers and clutter, ensure neat lines, and be well insulated to prevent short circuits or leakage.

Irregular grounding: The small power distribution unit should have a good grounding system to avoid electric shock and equipment damage caused by poor grounding.

Poor sealing of the small power distribution unit: Ensure that the small power distribution unit is well sealed to prevent dust and foreign matter from entering and affecting the accuracy and safety of the meter.

Ignoring safety signs: Clear warning signs should be posted on the small power distribution unit to remind users and maintenance personnel to pay attention to safety and prevent misoperation.

By avoiding these problems, the safe and reliable operation of the small power distribution unit can be ensured, the life of the equipment can be extended, and the normal operation of the power system can be guaranteed.
