1.3 Electrical Safety
Grounding
● 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 its 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.
AC and DC Power
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 making electrical connections, switch o the disconnector on the
upstream device to cut
o the power supply if people may contact energized
components.
● Before connecting a power cable, check that the label on the power cable is
correct.
