2.2. Connect OIT to PLC/Host and Power
Each PLC/host supported by Maple Systems has its own wiring requirements.
Maple Systems offers pre-constructed OIT-to-PLC operating cables for most
PLCs. Most cables are available for same day shipment from Maple Systems.
They are built and tested for high reliability and are strongly recommended.
Maple Systems also builds custom cables—contact the factory for information.
Components and instructions necessary to construct your own OIT-to-PLC
operating cables are also available. Refer to Maple Systems’ Price List or web site
(www.maple-systems.com).
NOTE: Refer to the STEP1 Protocol Operation Manual for information on
constructing OIT-to-ASCII host operating cables.
STEPS
1. Remove the four screws from the back of the OIT enclosure and open the two
halves.
2. A strain relief is provided for wiring access and sealing. The cable must be
inserted through the strain relief and into the cover.
3. Remove the black heatshrink tubing from the end of the OIT operating cable.
4. Slide the ferrite coil over the OIT operating cable. This usually requires
rotating the ferrite coil back and forth while simultaneously pulling on the
OIT operating cable.
5. Slide the ferrite coil up against the inside wall of the OIT enclosure and pull
through enough additional cable to reconnect the OIT operating cable wires.
