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.
