Basic System Description
Section 2-2
Four LED indicators (B) allow easy diagnosis. An attached grounding cable
(E) is sized to reach the ground terminals on all Inverter models. A feature 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 connector (D)
allows unstrained connection and removal of the PROFIBUS 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.

LED Indicators
The LED indicators on the front indicate the operational mode and status of
the Option Board and the network.
Refer to
Section 5-1
for Troubleshooting using the LED indicators on page 57

Basic System Description
The Option Board connects to the Master via a PROFIBUS network cable.
Inverter I/O data is generally shared with the Master's I/O memory through the
PROFIBUS DP network. Every PROFIBUS communication cycle, Inverter I/O
data is collected by the Option Board and exchanged with the Master. The
Engineering Station allows you to configure, monitor, program, diagnose and
operate the system.
