Four LED indicators allow easy diagnosis. An attached grounding cable is
sized to reach the ground terminals on all MX2-A@ Inverter models. A feature
in the housing will retain the mounting screw when the Option Board is not
mounted to the Inverter. The orientation of the Fieldbus connector allows
unstrained connection and removal of the PROFIBUS connector. Please pay
special attention to the Option Board connector: It must be properly con-
nected with the Inverter when the Option Board is mounted.
The LED indicators on the front indicate the operational mode and status of
the Option Board and the network.
