IT-M3900D 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.
