Installation and Wiring
Connecting the Communication
Cable to the Module
Follow these steps to connect your module.
1.
Verify that the cable/connector is correctly wired (see Figure 3.6
and Figure 3.7).
2.
Locate the D-shell connector at the base of the PD1 Module.
3.
Plug cable/connector into the PD1 D-shell connector and secure.

Profibus Connection
* Termination is required at both ends of the network.
The Profibus master might offer on-board termination.
Make sure that other Profibus slaves with on-board termination are set
up correctly.
Profibus Network Termination
The network must be terminated at the first (network master) and the
last PD1 module. A bus cable connector with an internal resistor
network must be used as no internal termination is provied on the
PD1 module. (Refer to Figure 3.7).
