1.3 Electrical Safety
Grounding Requirements
●
For the equipment that needs to be grounded, install the protective earthing
(PE) cable first when installing the equipment and remove the PE cable last
when removing the equipment.
●
Do not damage the ground conductor.
●
Do not operate the equipment in the absence of a properly installed ground
conductor.
●
Ensure that the equipment is connected permanently to the protective
ground. Before operating the equipment, check the electrical connection to
ensure that it is securely grounded.
General Requirements
D ANGER
Before connecting cables, ensure that the equipment is intact. Otherwise, electric
shocks or fire may occur.
●
Ensure that all electrical connections comply with local electrical standards.
●
Obtain approval from the local electric utility company before using the
equipment in grid-tied mode.
●
Ensure that the cables you prepared meet local regulations.
●
Use dedicated insulated tools when performing high-voltage operations.
DC Operation
D ANGER
Do not connect or disconnect power cables with power-on. Transient contact
between the core of the power cable and the conductor will generate electric arcs
or sparks, which may cause fire or personal injury.
●
Before connecting cables, switch off the disconnector on the upstream
equipment 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.
