3 Installation
The installation of SCADAPack controllers requires mounting the controller on the 7.5mm by 35mm
DIN rail and connecting the SCADAPack controller to the system I/O Bus. Refer to the System
Configuration Guide, at the beginning of this manual, for complete information on system layout,
I/O Bus cable routing and SCADAPack controller installation.
3.1 Field Wiring
SCADAPack controllers use screw termination style connectors for termination of field wiring.
These connectors accommodate solid or stranded wires from 12 to 22 AWG. The connectors are
removable allowing replacement of the SCADAPack Controller without disturbing the field wiring.
Leave enough slack in the field wiring for the connector to be removed.
CAUTION: Remove power before servicing unit.
To remove the termination connector:
• Pull the connector upward from the board. Apply even pressure to both ends of the connector.
• To install the termination connector:
• Line up the pins on the module with the holes in the connector. Make sure all the pins line up
properly.
• Push the connector onto the pins. Apply even pressure to both ends on the connector.
There are six connectors for field wiring. Refer to Figure 2: SCADAPack LP Board Layout for
connector locations.
• The two RS-232 communication ports, COM 2 and COM 3, connect to 8 pin modular jacks.
Refer to section 10.1-RS-232 Serial Communications Ports for pinout details and wiring
diagrams for these modular jacks.
• All other field wiring terminates in removable terminal connectors. Connector pinouts and
wiring examples are described in each of the respective sections of this manual.
