Before making electrical connections, switch off the disconnector on the
upstream device to cut off the power supply if people may contact energized
components.
Before connecting a power cable, check that the label on the power cable is
correct.
If the equipment has multiple inputs, disconnect all the inputs before
operating the equipment.
When routing cables, ensure that a distance of at least 30 mm exists between
the cables and heat-generating components or areas. This prevents damage
to the insulation layer of the cables.
Bind cables of the same type together. When routing cables of different types,
ensure that they are at least 30 mm away from each other.
Ensure that the cables used in a grid-tied PV power system are properly
connected and insulated and meet specifications.
Ensure that the equipment is installed in a well ventilated environment.
To prevent fire due to high temperature, ensure that the ventilation vents or
heat dissipation system are not blocked when the equipment is running.
Do not expose the equipment to flammable or explosive gas or smoke. Do
not perform any operation on the equipment in such environments.
Use wooden or fiberglass ladders when you need to perform live working at
heights.
When a step ladder is used, ensure that the pull ropes are secured and the
ladder is held firm.
Before using a ladder, check that it is intact and confirm its load bearing
capacity. Do not overload it.
Ensure that the wider end of the ladder is at the bottom, or protective
measures have been taken at the bottom to prevent the ladder from sliding.
Ensure that the ladder is securely positioned. The recommended angle for a
ladder against the floor is 75 degrees, as shown in the following figure. An
angle rule can be used to measure the angle.
