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.
