2. Control Panel Design Guidelines
The following guidelinesare intended to illustrate proper installationof the OIT to
help minimize electrical noise, which may hamper normal operation. It is the
responsibility of the customer to ensure that all wiring and other components
used in the control system meet Class I, Division 2 requirements. This
installation manual is intended only asa general guide to beused in conjunction
with the appropriate Class I, Division 2 installation and wiring requirements.
The customer is ultimately responsible for proper installation.
Pay careful attention to the placement of system components and associated cable
routing. These items can significantly enhance the performance and integrity o
f
your control application.
2.1. Control Panel Grounding
•
The control panel should be connected to a good, high-integrity earth ground
both for safety considerations and shielding purposes. This must be a reliable
earth ground with a low-resistance path. The ideal earth ground would be a
copper grounding rod located close to the OIT and the control panel.
•
Hinged doors on controlpanels do not provide along term electricalconnection
to the rest of the enclosure. Corrosion develops over time and prevents good
electrical contact. For thisreason, a separatewire braid should be installed from
the hinged control panel to the rest of the enclosure.
1010-0105, REV 03
INSTALLATION MANUAL 7
Figure 1 Control Panel Example
2.2. Power Supply Selection
•
The power supply used to power the OIT should have an output between +12
and +30 VDC, meeting Class 2 power requirements. The voltage should
measure between +12 and +30V at the OIT between Pins 1 and 2 of the power
connector. A 24 VDC, 1.2 amp linear power supply dedicated to the OIT is
recommended.
•
The powercable for theOIT should be18AWG 2-conductor stranded wire with
a shield wire and protective shield (foil or braid). The shield of the OIT power
cable mustbe connected to earthground at bothends of thecable. Please refer to
the “Connect OIT to Power” section for more information.
•
A power line filter installed at the AC input to the OIT power supply is highly
recommended asa safeguard against conducted RFnoise, which isoften present
on factory power lines. The wires connecting the outputof thepower line filter
to the power supply should be kept as short as possible to minimize any
additional noisepickup. The case of thepower linefilter should be connected to
a quietearth ground. The power linefilter should havea current ratingof at least
three amps with common mode and differential mode attenuation.
• The power supply that provides power to the OIT should not be used to power
switching relaysor solenoidsunlessnoise filter capsare connectedto each relay.
2.3. OIT Cable Routing
•
Input and output (I/O) wiring must be in accordance with Class I, Division 2
wiring methods and in accordance with the authority having jurisdiction.
•
Always routethe OIT communicationcable and power cableaway from anyAC
voltage or PLC/host control wires.
•
Never bundle the OIT cables together with120 VAC 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 120 VAC are used in the system,
greater separation is required.
•
If theOIT cablesmustcome near ACwiring, make surethey crossat 90 degrees.
•
Running ACpower wires ina separate groundedconduit is the preferredmethod
for electrical noise reduction.

NOTE: The power connector on the OIT has M3 slotted screws.
3.5. Connect OIT to PLC/Host
Each PLC/host supported by Maple Systems has its own wiring requirements.
Maple Systems offers pre-constructed OIT-to-PLC communication cables for
most PLCs. Most cablesare available for sameday shipment fromMaple Systems.
They arebuilt and tested for high reliabilityand are stronglyrecommended. Maple
Systems also builds custom cables—contact the factory for information.
Components and instructions necessary to construct your own OIT-to-PLC
communications cables are also available. Refer to Maple Systems’ Price List or
web site (www.maple-systems.com).
NOTE: Refer tothe ASCII SlaveProtocol Guide or theSTEP1 Protocol Operation
Manual for information on constructing OIT-to-ASCII host communication
cables.
STEPS
1. Connect the RJ-45 plug end of the communication cable into the serial port
on the OIT.
2. Ensure that the locking tab has secured the plug.
1010-0105, REV 03
INSTALLATION MANUAL 13
Figure 5 OIT3160/4160 PLC Connection
3.4. Connect OIT to Power
WARNING Use only with Class 2 power source limited to 30 VDC
open circuit and 8A short circuit.
The power cable for the OIT should be 18AWG 2-conductor wire with a shield
wire and protective shield foil. Maple Systems sells cable P/N 6030-0009 by the
foot for user-built power cables.
STEPS
1. The power cable should not be any longer than necessary. Prepare the
cable as follows:
a) Cut the power cable to the appropriate length.
b) Strip the cable shield back to expose the two insulated wires and the
bare shield wire on both ends of the power cable.
c) Strip the insulation from the two insulated wires. For the OIT end, this
is 0.27 inch (7 mm).
1010-0105, REV 03
12 OIT3160B/4160B
Figure 4 OIT3160/4160 Power Supply Connection
•
Keep thelengths of the OITcables as shortas possible. Do not coilexcess cable
and place it next to AC powered equipment.
2.4. Other Steps to Improve Noise Immunity
•
Always install the OIT’s rear cover. This provides a shield against electrical
noise whichcan be generatedin the controlpanel by relays, motors,power lines,
and/or high frequency equipment. Ensure that all rear cover mounting screws
are properly secured.
•
Any equipment used in the enclosure that operates at high frequency or high
current levels can be covered with a grounded metal shield.
INSTALLATION MANUAL 9
1010-0105, REV 03
3. OIT Installation
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
connectors provide quick connection for power and communications wiring.
•
There isone serial port with an RJ-45shielded jack. This port is used toconnect
to the PLC and to configure the OIT.
•
A separate three-position terminal block is supplied to provide power to the
OIT.
3.1. Prepare Panel for OIT Mounting
The OIT3160 and OIT4160 are mounted to a control panel from the front. For a
proper NEMA 4/12 seal, you will need:
• A panel with a maximum thickness of 0.125 inches (3.2 mm).
• A panel with a minimumthickness of 16-gauge (0.059 inches; 1.5 mm)steel or
10-gauge (0.102 inches;2.6 mm) aluminum. Thinner panels may bow between
the mounting studs, requiring the use of a stiffener on the rear.
• The surface of the panel, where the panel comes into contact with the gasket,
must be free of scratches, pits, and other features that prevent the gasket from
sealing properly.
The diagram inAppendix D shows the dimensionsof the panel cutout required for
proper installation. This panel cutout illustration is shown actual size and can be
photocopied to be used as a template. Check photocopy accuracy with the printed
check dimension. The panel cutout should becleaned and deburred before the OIT
is installed.
3.2. Enclosures
Allow enough spacing within an enclosure for adequate ventilation. For some
applications, you may have to consider heat produced by other devices within a
panel. The ambient temperature around the terminal must be maintained as
specified.
10 OIT3160B/4160B
1010-0105, REV 03
3.3. Mount OIT to Panel
STEPS
1. Gently position the OIT with the studs through the panel mounting holes.
2. Secure the OIT by installing the four #6-32UNC mounting nuts using a
5/16 inch socket wrench or nut driver.
CAUTION: Do not torque the 4 mounting nuts to over 15 pound-inches. Ove
r
torquing can strip the threads or pull the studs loose.
RE-INSTALLING: Because the gasket will take a “set” to the panel, be sure to
re-install any OIT to the same panel cutout when a NEMA 4/12 seal is required.
