2. Optional communication slot: This slot is a very powerful extension slot
now and future. Inverter can accept card special design for the slot only.
There are 2 kinds of cards can be applied now. One is RS485 card and
the other is SNMP (Simple Network Management Protocol) card. In the
future, extension card such as data logger or others may be developed.
For card detail information, please refer to use manual of individual card.
3. F/W upgrade: To keep the firmware newest, one can use RS232 port
and special program to upgrade inside F/W. To do this, please contact
with your local representative.
We do not suggest end-user to upgrade the f/w himself. There is risk to do
that without proper operations!
