cause electric arcs, sparks, re, or explosion, which may result in 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.

● Do not touch the power supply equipment directly or with conductors such as

damp objects. Before touching any conductor surface or terminal, measure

the voltage at the contact point to ensure that there is no risk of electric

shock.

● Do not touch operating equipment because the enclosure is hot.

● Do not touch a running fan with your hands, components, screws, tools, or

boards. Otherwise, personal injury or equipment damage may occur.

shocks or re may occur.

D ANGER

Non-standard and improper operations may result in re or electric shocks.

D ANGER

Prevent foreign matter from entering the equipment during operations. Otherwise,

equipment damage, load power derating, power failure, or personal injury may

occur.

WARNING

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.

CA UTION

Do not route cables behind the air intake and exhaust vents of the equipment.

General Requirements

● Follow the procedures described in the document for installation, operation,

and maintenance. Do not reconstruct or alter the equipment, add
