The wireless communication card is especially useful for scenarios where you cannot directly
use the keypad to operate the VFD due to the restriction of the installation space. With a
mobile phone APP, you can operate the VFD in a maximum distance of 30 m. You can choose
a PCB antenna or an external sucker antenna. If the VFD is located in an open space and is a
molded case machine, you can use a built-in PCB antenna; and if it is a sheetmetal machine
and located in a metal cabinet, you need to use an external sucker antenna.
When installing a sucker antenna, install a wireless communication card on the VFD first, and
then lead the SMA connector of the sucker antenna into the VFD and screw it to CN2, as
shown in the following figure. Place the antenna base on the chassis and expose the upper
part. Try to keep it unblocked.
