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 instrument is provided with a power cord during delivery and

should be connected to a socket with a protective earth terminal, a

junction box or a three-phase distribution box. Before operation, be

sure that the instrument is well grounded.

Please always use the provided cable to connect the instrument.

Check all marks on the instrument before connecting the instrument

to power supply.

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.

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.

SHOCK HAZARD Ground the Instrument. This product is provided

with a protective earth terminal. To minimize shock hazard, the

instrument must be connected to the AC mains through a grounded

power cable, with the ground wire firmly connected to an electrical

ground (safety ground) at the power outlet or distribution box. Any

interruption of the protective (grounding) conductor or disconnection

of the protective earth terminal will cause a potential shock hazard

that could result in injury or death.

Before applying power, verify that all safety precautions are taken. All

connections must be made with the instrument turned off, and must

be performed by qualified personnel who are aware of the hazards

involved. Improper actions can cause fatal injury as well as

equipment damage.

SHOCK HAZARD, LETHAL VOLTAGES This product can output the

dangerous voltage that can cause personal injury, and the operator

must always be protected from electric shock. Ensure that the output

electrodes are either insulated or covered using the safety covers

ООО "Техэнком" Контрольно-измерительные приборы и оборудование www.tehencom.com

IT-M7700 Programming Guide

provided, so that no accidental contact with lethal voltages can

occur.

Never touch cables or connections immediately after turning off the

instrument. Verify that there is no dangerous voltage on the

electrodes or sense terminals before touching them.

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.

Make sure the vent hole is always unblocked.
