3.0 INSTALLATION
This section describes how to install and remove the module and its
cable assembly.
3.1 Wiring
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.
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. Fasten the two field wires to a 25 pin male DĆshell
connector. Typical field connections are shown in figure
3.1. Make certain that the other end of the cable is
connected to the proper connector on the Toledo Scale
digital indicator. Refer to figure 3.2 for the proper digital
indicator connection.
Refer to Appendix C for the arrangement of terminal board
connections. All field wires should be fastened securely.
