When operating Emerson products, the operation personnel must observe the safety rules in the industry, the

general safety points and special safety instructions specified in this book.

Electrical Safety

I. Hazardous voltage

Danger

Some components of the power supply system carry hazardous voltage in operation. Direct contact or indirect contact

through moist objects with these components will result in fatal injury.

Observe safety rules in the industry when installing the power supply system. The installation personnel must be

licensed to operate high voltage and AC power.

In operation, the installation personnel are not allowed to wear conductive objects, such as watches, bracelets,

bangles and rings.

When you spot the cabinet with water or moisture, turn off the power immediately. In moist environment,

precautions must be taken to keep moisture out of the power supply system.

"Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during

installation.

Danger

High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance

with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high

voltage operations.

II. Tools

Warning

In high voltage and AC operation, specialized tools must be used.

III. Thunderstorm

Danger

Never operate on high voltage, AC, iron tower or mast in the thunderstorm.

In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be

well earthed in time to avoid damage by lightning strikes.
