●
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.
Cabling
●
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.
1.4 Installation Environment Requirements
●
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.
1.5 Mechanical Safety
Using Ladders
●
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.
