Safety Precautions

The following safety precautions must be observed during all phases of opera-

tion of this instrument. Failure to comply with these precautions or specific warn-

ings elsewhere in this manual will constitute a default under safety standards of

design, manufacture and intended use of the instrument. ITECH assumes no li-

ability for the customer’s failure to comply with these precautions.

IT-M7700 Series User Manual

•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 instru-

ment 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 elec-

tric shock.

•Do not install alternative parts on the instrument or perform any un-

authorized 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.

IT-M7700 Series User Manual

•SHOCK HAZARD Ground the Instrument. This product is provided

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

strument 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 disconnec-

tion 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 out-

put electrodes are either insulated or covered using the safety cov-

ers 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 electro-

des or sense terminals before touching them.

•After using the device, turn off the power switch of the device be-

fore unplugging the power cord or disassembling the terminals. Do

not touch the cable or the terminal immediately. Depending on the

model, the dangerous voltage at the plug or terminal is maintained

for 10 seconds after the device is switched off. Make sure that there

is no dangerous voltage 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.
