2.3 Electrical Safety
Grounding Requirements
● For the equipment that needs to be grounded, install the ground cable
rst
when installing the equipment and remove the ground 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
Before connecting cables, ensure that the equipment is intact. Otherwise, electric
shocks or re may occur.
● Ensure that all electrical connections comply with local electrical standards.
● Ensure that the cables you prepared meet local regulations.
● Use dedicated insulated tools when performing high-voltage operations.
DC Operation
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 re or personal injury.
● Before connecting cables, switch o the disconnector on the upstream
equipment to cut
o the power supply if people may contact energized
components.
