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 CAN RESULT IN SERIOUS BODILY INJURY OR LOSS OF
LIFE.
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 from the system to the external devices. For detailed
recommendations refer to IEEE 518.
3.2 Initial Installation
Usethefollowing procedureto install themodule:
Step 1.
Turn off power to the system.
Step 2. If oneor both of theRSĆ232C ports on theProcessor are
to be used by application tasks for serial communication
with devices other than the personal computer, use
shielded RSĆ232 cables. Cable connectors must be
equipped with EMI/RFIĆshielded cable clamps attached to
thecableshield. Thecableshield must begrounded at
oneend. Thecablelength must bein accordancewith the
RSĆ232 specification. Besureto label theconnector so
that it can be easily reconnected later should it ever need
to be removed. A pin description can be found in
Appendix C.
Step 3. Take the module out of its shipping container. Take it out of
the antiĆstatic bag, being careful not to touch the
connectors on theback of themodule.
Step 4. Activate the onĆboard battery. When viewing the Processor
module from the front, you can access the battery through
theopening in theright wall portion of theProcessor's
protective enclosure. Activate the battery by taking it out of
its holder and removing the tape that covers it. Replace
the battery in its holder. Make certain that the battery is
facing in the proper direction, i.e., the end marked +" on
the battery is facing the end marked +" on the battery
holder.
Notethat thebattery will begin to chargethe
superĆcapacitor as soon as the battery is replaced in its
holder. For maximum battery life, you should not remove
