1.1 Personal Safety
D ANGER
Ensure that power is o during installation. Do not install or remove a cable with
power on. Transient contact between the core of the cable and the conductor will
generate electric arcs or sparks, which may cause a re or personal injury.
D ANGER
Non-standard and improper operations on the energized equipment may cause
re, electric shocks, or explosion, resulting in property damage, personal injury, or
even death.
D ANGER
Before operations, remove conductive objects such as watches, bracelets, bangles,
rings, and necklaces to prevent electric shocks.
D ANGER
During operations, use dedicated insulated tools to prevent electric shocks or short
circuits. The dielectric withstanding voltage level must comply with local laws,
regulations, standards, and specications.
