Chapter 1 - Installation of OITs
Before You Begin
Please read the following for proper handling of your new OIT.
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.
Managing Electrostatic Discharge
It is best NOT to remove the rear enclosure of the OIT. When the rear part of the enclosure 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 a static-free grounded workstation
• Connecting the frame ground () connector of the OIT to a clean earth ground
• Placing the OIT in an anti-static bag during transport
CE Compliance
The Blue Series OITs have been tested to conform to European CE requirements per Council Directive 89/336/EEC. The
European Union created these requirements to ensure conformity among products traded in those countries. Specifically, the
Blue Series OITs meet or exceed the noise emissions and immunity requirements as set forth in the EN50081 (Emissions)
and EN50082 (Immunity) standards. These products are designed to withstand electrical noise in harsh industrial
environments. They also conform to requirements that limit electrical emissions. However, this does not guarantee that the
products will be totally immune from possible malfunction in cases where severe electrical noise occurs. Therefore, we
strongly recommend that you follow the guidelines outlined in this chapter for proper wire routing and grounding to insure
the proper operation of the Blue Series OIT.
NEMA Rating
The Blue Series OITs are rated for NEMA 4/12 or IP65 installations. This means that when the OIT is properly mounted to a
panel or other enclosure, the front enclosure of the OIT will provide protection to the inside of the panel from splashing
water, wind blown dust, rain, or hose-directed water. The OIT must be installed according to the instructions in this chapter
to be properly sealed.
Environmental Considerations
The Blue Series is designed to operate in temperatures from 0-50° C. It is intended primarily for indoor installations and may
not be suitable for certain outdoor applications. Avoid installing the Blue Series in environments with severe mechanical
vibration or shocks. Do not install the OIT in enclosures with rapid temperature variations or high humidity. Either may
cause condensation of water inside the device and eventual damage to the OIT.
