3.0 INSTALLATION
This section describes how to install and remove the module and its
cable assembly.
3.1 Wiring
The installation ofwiring should conform to all applicable codes.
To reduce the possibility ofelectrical noise interfering with the proper
operation ofthe control system, exercise care when installing the
wiring from the system to the external devices. For detailed
recommendations refer to IEEE 518.
3.2 Initial Installation
Use the following procedure to install the module:
Step 1.
Turn off power to the system. All power to the rack as well
as all power to the wiring leading to the module should be
off.
Step 2. Mount the terminal strips (M/N 57C375) on a panel. The
terminal strips should be mounted to permit easy access
to the screw terminals on the terminal strips. Make certain
that the terminal strips are close enough to the rack so that
the cable will reach between the terminal strips and the
module.
Step 3. Fasten field wires to the terminal strips. Typical field
connections are shown in figures 3.1, 3.2, and 3.3.
Refer to Appendix C for the arrangement of terminal board
connections. Make certain that all field wires are securely
fastened.
