It supports PTC input, while PTC acts at 2.5kΩ, and it supports the
input of only dry contacts sharing COM.
Note:
You can install optional expansion cards for 1.5
–5.5kW VFD models and you are recommended
to install them at slot 2.
I/O expansion card 2 has been installed at slot 3 for 7.5kW and higher VFD models as standard
configuration.
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.
