Safety Precautions

The following safety precautions must be observed during all phases of

operation of this instrument. Failure to comply with these precautions or specific

warnings elsewhere in this manual will constitute a default under safety

standards of design, manufacture and intended use of the instrument. ITECH

assumes no liability for the customer’s failure to comply with these precautions.

Do not use the instrument if it is damaged. Before operation, check the

casing to see whether it cracks. Do not operate the instrument in the

presence of inflammable gasses, vapors or dusts.

The electronic load is provided with a power line during delivery and should

be connected to a socket with a protective earth terminal. Before operation,

be sure that the instrument is well grounded.

Make sure to use the power cord supplied by ITECH.

Check all marks on the instrument before connecting the instrument to

power supply.

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

of bearing maximum short-circuit current of electronic load without

overheating. If there are multiple electronic loads, each pair of the power

cord must be capable of bearing the full-loaded rated short-circuit output

current

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.

If you use the power supply to charge the battery, pay attention to the

positive and negative polarity of the battery when wiring, otherwise the

power supply will be damaged!

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

unauthorized modification.

Do not use the instrument if the detachable cover is removed or loosen.

To prevent the possibility of accidental injuries, be sure to use the power

adapter supplied by the manufacturer only.

We do not accept responsibility for any direct or indirect financial damage

or loss of profit that might occur when using the instrument.

This instrument is used for industrial purposes, do not apply this product to

IT power supply system.

Never use the instrument with a life-support system or any other equipment

subject to safety requirements.

Failure to use the instrument as directed by the manufacturer may render

its protective features void.

Always clean the casing with a dry cloth. Do not clean the internals.
