4.5 Wiring protection
4.5.1 Protecting the VFD and input power cable in case of short circuit
The VFD and input power cable can be protected in case of short circuit, avoiding thermal overload.
Carry out protective measures according to the following figure.

Fuse
Figure 4-22 Fuse configuration
Note: Select the fuse according to the manual. In case of short circuit, the fuse protects input power
cables to avoid damage to the VFD; if internal short-circuit occurs to the VFD, it can protect
neighboring equipment from being damaged.
4.5.2 Protecting the motor and motor cable in case of short circuit
If the motor cable is selected based on VFD rated current, the VFD is able to protect the motor cable
and motor during short circuit without other protective devices.
 If the VFD is connected to multiple motors, use a separated thermal overload
switch or breaker to protect the cable and motor, which may require the fuse to
cut off the short circuit current.
