Safety Precautions

General safety precautions below must be followed in each phase of instrument

operation. In case of failure to follow these precautions or specific warnings in

other parts of the manual, violation against the safety standards related to the

design, manufacture and purpose of the instrument will occur. If the user does

not follow these precautions, ITECH will bear no responsibility arising there

from.

Working voltage of IT8800 series includes 110V/220V. To prevent burnout,

be sure to check whether the AC voltage setting of electronic load is

consistent to the supply voltage before start-up!

The electronic load is provided with a three-core power line during delivery

and should be connected to a three-core junction box. Before operation, be

sure that the electronic load is well grounded.

Use electric wires of appropriate load. All loading wires should be capable

of bearing maximum short-circuit of electronic load without overheating.

Ensure the voltage fluctuation of mains supply is less than 10% of the

working voltage range in order to reduce risks of fire and electric shock.

To prevent burnout, please pay special attention to positive and negative

polarities of electronic load during connection!

Do not use damaged equipment. Please check the housing before using

the equipment. Check whether the instrument is subject to cracking or is

lack of plastic. Do not operate the instrument in the environment with

explosive gas, steam or dust.

Observe all tags on the equipment before connection.

Do not install alternative parts on the instrument or perform any

unauthorized modification.

Do not use the equipment when the removable cover is dismantled or

loose.

Please use the power adapter supplied by the manufacturer to avoid

accidental injury.

Do not use the equipment on the life support system or other equipment

with safety requirements.

If the equipment is not used in the manner specified by the manufacturer,

its protection may be damaged.

Always use dry cloth to clean the equipment housing. Do not clean the

inside of the instrument.

Do not block the air vent of the equipment.
