A.3 Attach the base module
The base module provides a connection for a display module and contains a connection
and the terminating resistor for the sc1000 network. The LED on the front indicates the
status of the network communication.
The base module is required for any additional modules.
Prior to installing the base module, make sure the DIN rail is mounted correctly and that
all safety requirements are met.
1. Deactivate the switch (network termination) on the module (Figure 75).
2. Remove power and disconnect all cable connections to the module.
3. Place the Base Module on the DIN rail.
4. Make the connections as shown in Figure 76 and Table 49.
