User Manual of TI120 Series Variable Frequency Drive
Note
All our products have been subjected to withstand voltage test before leaving the factory. It
is forbidden to conduct this test on the variable frequency drive; otherwise there is a risk of
equipment damage!
Terminal signal lines of the variable frequency drive shall be far away from main power
line, and they be vertically crossed under the condition that the distance cannot be guaranteed,
otherwise the control signals shall be interfered!
When the length of motor cable is more than 100m, it is recommended to select output
reactor, otherwise there is a risk of equipment failure!
The encoder must use shielded cable and the shielding layer must be grounded correctly!
■ Operation
Danger
If the storage time of the variable frequency drive exceeds 2 years, the voltage regulator
shall be applied to boost the voltage gradually, otherwise there is a risk of equipment damage!
After the wiring is finished according to the requirements of section 2.3, the variable
frequency drive can only be powered on; otherwise there is a risk of equipment damage or
electric shock!
After the variable frequency drive wiring is confirmed to be correct, the power can only be
turned on after the cover plate is covered. It is forbidden to open the cover plate after the power
is turned on; otherwise there is a risk of electric shock!
After the variable frequency drive is powered on, do not touch the variable frequency drive
and its peripheral circuits regardless of the state of the variable frequency drive, otherwise
there is a risk of electric shock!
Before running the variable frequency drive, it must check there is no person in
surrounding area who can reach the motor so as to prevent personal injury.
D
uring the operation of the variable frequency drive, foreign matters shall be avoided from
falling into the equipment; otherwise there is a risk of equipment damage!
N
on-professional technicians are forbidden to test signals during operation, otherwise
there is a risk of personal injury or equipment damage!
Do not change variable frequency drive parameters at will; otherwise there is a risk of
equipment damage!
