TI120 Series Variable Frequency Drive
System Installation and Wiring
- 10 -
motor cable is more than 100m, an AC output reactor must be installed near the variable
frequency drive.
5)
Grounding terminal
● Terminals must be reliably grounded and the resistance of grounding wire must be less than
10Ω. Otherwise, the equipment will work abnormally or even be damaged.
● Do not share the grounding terminal
with the N terminal of the neutral line of the power
supply.
●
The impedance of the protective grounding conductor must meet the requirement of
withstanding short-circuit large current in case of failure.
● The size of the protective grounding conductor shall be selected according to the following
table.
