The LED indicators (B) allow easy diagnosis. An attached grounding cable (E)
is sized to reach the ground terminals on all MX2-A@ Inverter models. A fea-
ture in the housing (F) will retain the mounting screw (G) when the Option
Board is not mounted to the Inverter. The orientation of the Fieldbus connec-
tor (D) allows unstrained connection and removal of the CompoNet connector.
Please pay special attention to the Option Board connector: It must be prop-
erly connected 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.
