3.3 Layout protection

3.3.1 Protect the inverter and input power cable in short-circuit situations
Protect the inverter and input power cable in short circuit situations and against thermal overload.
Arrange the protection according to the following guidelines.
Note: Select the fuse specified in this manual. The fuse will protect the input power cable from short circuit. It will
protect the surrounding devices in case of inverter internal short circuit.
3.3.2 Protecting the motor and motor cables
The inverter protects the motor and motor cable in a short-circuit situation when the motor cable is sized according
to the rated current of the inverter. No additional protection devices are required.

Description
(Relay contact rating: 3A/AC250V,1A/DC30V)
1. Internal impedance:3.3kΩ
2. 0~4V corresponds to low electric level input and 7~30V
corresponds to high electric level input
3. Max input frequency:1kHz
4. All are programmable digital input terminal. User can set the
terminal function through function codes.
Common terminal for S5/Y and switch by J1
Note : S5 and Y can not be used at the same time
