This section describes how to install and remove the module and its
cable assembly.
The installation of wiring should conform to all applicable codes.
To reduce the possibility of electrical noise interfering with the proper
operation of the control system, exercise care when installing the
wiring from the system to the external devices. For detailed
recommendations refer to IEEE 518.
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 strip (M/N 57C371) on a panel. The
terminal strip should be mounted to permit easy access to
the screw terminals. Make certain that the terminal strip is
close enough to the rack so that the cable will reach
between the terminal strip and the module.
Step 3. Fasten field wires to the terminal strip. Typical field
connections are shown in figure 3.1.
Refer to Appendix C for the arrangement of terminal board
connections. Make sure that all field wires are securely
fastened. Note that for any voltage or current input other
than +10 volts or + 1 volt, an external resistor must be
mounted on the terminal strip.
