DC Ground
A DC ground cable may or may be installed depending on the system
requirements (system installation environment, cabinet structure, power
supply system). This cable is generally connected to the ground of the power
supply unit. Connection between more than one IDD may be in a daisy
chain.
External Operator Panel
The external operator panel is installed only when required for the system.
If it is unnecessary, pins 1 to 4 of CN7 connector for the external operator
panel on the IDD must be opened. Also, necessary features must be set on
CN3 or CN9 using the short plug. (See 'Setting Terminals in section 3.)
Figure 2.21 shows a recommended circuit for the external operator panel.
Since the external operator panel is not provided as an option, the user
must fabricate this panel, referring to the recommendation if necessary.
Note:
Necessary switches and LEDs for the system can be provided on the
external operator panel by referring to the recommended circuit shown
in Figure 2.21.
When there is no signal set for the external operator panel, the signal
must be set on CN3 (or on CN9) using the short plug. The CN3 or CN9
pins corresponding to the signal must be opened. For details, see
"Connectors" in this section and Setting Terminals" in section 3.
