Important Safety Information
This manual contains information and warnings that must be followed by the user for safe
operation and to keep the product in a safe condition.
General Safety Summary
Carefully read the following safety precautions to avoid personal injury and prevent damage to the
instrument and any products connected to it. To avoid potential hazards, please use the
instrument as specified.
To Avoid Fire or Personal Injury.
Use Proper Power Line.
Only use a local/state approved power cord for connecting the instrument to mains power sources.
Ground the Instrument.
The instrument grounds through the protective terra conductor of the power line. To avoid electric
shock, the ground conductor must be connected to the earth. Make sure the instrument is
grounded correctly before connect its input or output terminals.
Connect the Signal Wire Correctly.
The potential of the signal wire is equal to the earth, so do not connect the signal wire to a high
voltage. Do not touch the exposed contacts or components.
Look over All Terminals’ Ratings.
To avoid fire or electric shock, please look over all ratings and signed instructions of the instrument.
Before connecting the instrument, please read the manual carefully to gain more information about
the ratings.
Equipment Maintenance and Service.
When the equipment fails, please do not dismantle the machine for maintenance. The equipment
contains capacitors, power supply, transformers, and other energy storage devices, which may
cause high voltage damage. The internal devices of the equipment are sensitive to static electricity,
and direct contact is easy to cause irreparable damage to the equipment. It is necessary to return
to the factory or the company's designated maintenance organization for maintenance.
