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.
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.
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.
Do not use the equipment on the life support system or other equipment
with 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 input the
dangerous voltage that can cause personal injury, and the operator must
always be protected from electric shock. Ensure that the input electrodes
are either insulated or covered using the safety covers provided, so that no
accidental contact with lethal voltages can occur.
