Introduction
Thank you for purchasing a Maple Systems OIT3185 or OIT4185. You have
selected a rugged, reliable, and powerful operator interface for your application.
This booklet describes the steps necessary to ensure trouble-free OIT system
operation.
Please read this booklet carefully!!
Static Awareness
It is best NOT to remove the rear cover on the OIT. When the rear cover is removed
the circuitry inside is exposed to possible damage by electrostatic discharge during
handling. Minimize the possibility of electrostatic discharge by:
• Discharging personal static by grounding yourself prior to handling the OIT.
• Handling the OIT at static-free, grounded work station.
• Connecting the chassis of the OIT to a clean ground.
• Placing the OIT into an anti-static bag during transport.
Unpacking the Unit
Carefully unpack the OIT. Please read any instructions or cautions that appear on
the shipping container. Check all material in the container against the enclosed
packing list. Maple Systems, Inc., will not accept responsibility for shortages
against the packing list unless notified within 30 days. The equipment and its
accessories were inspected and tested by Maple Systems before shipment; all of the
equipment should be in good working order. Examine the equipment carefully; if
any shipping damage is evident, notify the carrier immediately. You are
responsible for claim negotiations with the carrier. Save the shipping container and
packing material in case the equipment needs to be stored, returned to Maple
Systems, or transported for any reason.
