A successful self-test indicates that the purchased product meets delivery
standards and it is available for normal usage.
Before operation, please confirm that you have fully understood the safety
instructions.
• Before connecting power cord, be sure to confirm that the power voltage
matches with the rated input voltage of the instrument.
• Before connecting power cord, be sure to switch off the instrument. Veri-
fy that there is no dangerous voltage on the connection terminals.
• To avoid fire or electric shock, make sure to use the power cord supplied
by ITECH.
• Be sure to connect the power cord to the AC distribution box with protec-
tive grounding. Do not use terminal board without protective grounding.
• Do not use an extended power cord without protective grounding, other-
wise the protection function will fail.
• Be sure to perform related operations and connections to feed energy
back to grid in accordance with related regulations, and meet all neces-
sary conditions.
• Ensure that the power cord connection terminals are either insulated or
covered by the supplied protective cover so that no accidental contact
with lethal voltage can occur.
