3.0 INSTALLATION
This section describes how to install the Local I/O Head.
DANGER
THE USER IS RESPONSIBLE FOR CONFORMING WITH THE NATIONAL
ELECTRICAL CODE AND ALL OTHER APPLICABLE LOCAL CODES. WIRING
PRACTICES, GROUNDING, DISCONNECTS, AND OVERĆCURRENT
PROTECTION ARE OF PARTICULAR IMPORTANCE. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN SERIOUS BODILY INJURY OR LOSS OF LIFE.
WARNING
UNEXPECTED OUTPUT CHANGES MAY RESULT IF A RAIL IS PLUGGED INTO A
LOCAL I/O HEAD THAT IS COMMUNICATING WITH A PROCESSOR OR REMOTE
I/O HEAD. ANY HARDWARE CONFIGURATION CHANGES MUST BE MADE ONLY
WITH THE LOCAL I/O INTERFACE CABLE (M/N 45C8) DISCONNECTED. FAILURE
TO OBSERVE THIS PRECAUTION COULD RESULT IN BODILY INJURY.
3.1 Wiring
To reduce the possibility of electrical noise interfering with the proper
operation of the control system, exercise care when installing the
wiring between the system and the external devices. For detailed
recommendations refer to IEEE 518.
3.2 Installation
Use the following procedure to install each Local I/O Head. Generally,
each Head is installed directly above the Rails or RailĆcompatible
devices with which it will be connected, leaving at least 2 inches of
clearance between the Head and the closest device. Multiple Heads
should be installed side by side, leaving at least 2 inches of clearance
in between Heads.
Step 1.
Using the mounting pattern in Appendix B, drill four holes
of approximately .218" diameter. The Head is designed to
be mounted vertically using #10 bolts or studs.
Step 2. Mount the Head using one of the two methods illustrated
in Appendix B.
Step 3. Attach a retainer clip to the connector at each end of the
Local I/O Interface cable (M/N 45C8). Note that the
faceplate connectors have slots that correspond to the
part of the retainer clip that protrudes away from the cable
connector. The retainer clip is used to ensure a tight
connection between the cable and faceplate connectors.
Step 4. Connect a Rail or RailĆcompatible device to one of the four
RAIL ports on the Head using the I/O Rail cable (M/N
45C5) that came with the device. Continue with any
remaining Rails. Instructions on mounting Rails and
RailĆcompatible devices are found in the instruction
manuals corresponding to the devices.
