CONTROL CONNECTIONS

The control connections (analog inputs/outputs, digital inputs/
outputs), must be made at the CC11 control board terminal strip XC1.

NOTE!
For changing to "Active Low" remove the jumpers
between XC1:11 and 12, place this jumper between
XC1:12 and 13 and connect common points of the
switches on DI1 to DI6 to XC1:11, instead of XC1:13.

Typical Control Connections
Control connection # 1 - Run/Stop function controlled from the
keypad (Local Mode).
With this control connection, it is possible to run the inverter in local
mode with the factory default settings.
This operation mode is recommended for first-time users, since no
additional control connections are required.
Control connection # 2 - 2-Wire Run/Stop function (Remote Mode).
This wiring example is valid only for the default factory settings and
if the inverter is set to remote mode.
With the factory default settings, the selection of the operation mode
(local/remote) is performed through the HMI key
default). Set P0220 = 3 to change the default setting of HMI key
to remote mode.
