Do not use the power supply used to provide power to the OIT to power switching relays, solenoids, or other active
devices.
Ca ble Routing and Noise Im mu nity
Follow these guidelines when routing cable to the OIT:
·
Always route the OIT communication cable and the power cable away from any AC voltage or rapidly
switching DC control lines.
·
Never bundle the OIT cables together with 120VAC power wires or with relay wiring.
·
Try to keep at least 8 inches (20 cm) of separation between the OIT cables and other power wiring. If
voltages greater than 120VAC are used in the system, greater separation is required.
·
If the OIT cables must come near AC wiring, make sure they cross at 90 degrees.
·
Run AC power wires in a separate grounded conduit to reduce electrical noise interference.
·
Keep the cable lengths for the OIT as short as possible. Do not coil excess cable and place it next to AC
powered equipment.
·
Cover any equipment used in the enclosure that operates at high frequency or high current levels with a
grounded metal shield.
In stal la tion
It is necessary to follow all installation procedures described in this chapter for electrical noise immunity and CE
compliance.
Your Maple Systems OIT is designed to connect easily to your PLC. External rear connectors provide quick
connections for power, communications and programming wiring.
There are two connectors for serial communications on the rear of the OIT. Both of these are D-subminiature 9-pin
connectors.
Use the supplied separate 3-position terminal block to provide power to the OIT.
Con nect the OIT to Power
The power cable for the OIT should be 18AWG, 2-conductor wire with a shield drain wire and protective shield
foil. You may buy cable P/N 6030-0009 by the foot from Maple Systems to make these.
