In tro duc tion

Thank you for purchasing a Maple Systems Silver Plus Series OIT. You have selected a
rugged, reliable, and powerful operator interface for your application. This booklet
describes the steps necessary to ensure easy installation of your Silver Plus Series OIT.

Please read this booklet carefully.

Static Aware ness

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.

Un pack ing 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.

Installation of OITs

CE Com pli ance

The Silver Plus 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 Silver Plus 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 Silver
Plus Series OIT.

NEMA Rat ing

The Silver Plus Series OITs are rated for NEMA 4/12 (indoor) 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 manual to be properly sealed.

En vi ron men tal Con sid er ations

The Silver Plus Series is designed to operate in temperatures from 0-45° C. It is intended for
indoor installations and not designed for outdoor applications. Avoid installing the Silver
Plus Series in environments with severe mechanical vibration or shocks. Do not install the
OIT in enclosures with rapid temperature variations or high humidity. Either will cause
condensation of water inside the device and eventual damage to the OIT.

Safety Pre cau tions

Please observe the following precautions when installing the Silver Plus Series OIT. Failure
to comply with these restrictions could result in loss of life, serious personal injury, or
equipment damage.

Warning: Do not operate the OIT in areas subject to explosion due to flammable gases,

vapors, or dusts.

Warning: Do not connect the OIT to an AC power source. You will cause permanent

damage to the OIT.

Warning: Do not attempt to use a DC power supply that does not meet OIT power

requirements. You may cause malfunction or permanent damage to the OIT.

Warning: Do not power the OIT with a DC power supply used for inductive loads or for

input circuitry to the programmable logic controller. Severe voltage spikes caused by these
devices may damage the OIT.

Con trol Panel De sign Guide lines

Pay careful attention to the placement of system components and associated cable routing.
These items can significantly enhance the performance and integrity of your control
application.

Con trol Panel Ground ing

The control panel should be connected to a good, high-integrity earth ground, both for safety
considerations and shielding purposes. Maple Systems cannot overemphasize the
importance of good grounding. If you fail to use good grounding procedures during
installation, sporadic malfunction of the OIT may occur:

• Connect the OIT’s chassis ground terminal to a reliable earth ground with a

low-resistance path.

• Route all earth ground wires that lead from the OIT, the PLC, the power supply, and the

line filter to a central earth ground point such as a barrier strip. This will ensure that no
ground current from one device influences the operation of the other devices.

• Connect the OIT chassis ground terminal to the control panel door using a heavy-gauge

short braided cable or ground wire to minimize resistance.
