SD39EAM-1r4 Installation

2 Installation
This section describes installation of the EAM and its associated assemblies. Review the steps in the
following section before continuing with EAM installation.
2.1 Preliminary Considerations and Preparation
Figure 2-1 shows typical local and marshalled I/O wiring. I/O connections between field devices and
either local or marshalled terminations are wired with user-supplied cable. Typical cable has a jacket and
two insulated, twisted-pair conductors with shield. This cabling is referred to as I/O cable.
When marshalled termination is employed, an Interconnect I/O Cable Assembly connects the EAM
Marshalled Termination Assembly to the MODULRAC and EAM. Interconnect I/O Cable Assembly
part numbers and their standard lengths are presented in section 5. An Interconnect I/O Cable length must
be determined before proceeding with the installation of hardware assemblies.
1. Install the MODULRAC and the Local Termination Panel (for local termination only) in the cabinet
where EAMs are to be installed. EAMs should not be installed in the MODULRAC at this time;
however, the MODULRAC slot numbers for EAM installation should be known.
2. If local I/O termination is employed, tag all I/O cables and route them into the cabinet. They should
be ready for cable end preparation and connection to the EAM Termination Strips.
3. If remote termination is employed, tag all I/O cables and route them into the marshalling cabinet.
They should be ready for cable end preparation and connection to the EAM Marshalled Termination
Assemblies.
Also, route the EAM Interconnect I/O Cable (or Unterminated I/O Cable) between the marshalling
cabinet and the cabinet containing the MODULRAC. See Figure 1-1; J1 will be installed in the
MODULRAC and P2 will connect to the EAM Marshalled Termination Assembly in the marshalling
cabinet.
