3.3 Wiring protection
3.3.1 Protect the VFD and input power cable in short-circuit situations
Protect the VFD and input power cable during short-circuit to aviod thermal overload.
Carry out protective measures according to the following requirements.
Input cable
VFD
Fuse
Figure 3-7 Fuse configuration
Note:
Select the fuse according to operation manual. During short-circuit, the fuse will
protect input power cables to avoid damage to the VFD; when internal short-circuit occurred
to the VFD, it can protect neighboring equipment from being damaged.
