NOTES:
1) 12-24 VDC must be supplied to the network
2) For detailed wiring information, refer to Chapter Two in the
Control Station Hardware Manual
(MAN0227),
where a checklist is provided that covers panel box layout requirements and minimum clearances.
10. INSTALLATION / SAFETY
WARNING:
Remove power from the OCS controller, CAN port, and any peripheral equipment connected to this local system before adding
or replacing this or any module
a)
All applicable codes and standards should be followed in the
installation of this product.
b)
Shielded, twisted-pair wiring should be used for best
performance.
c)
Shields are to be terminated to frame ground.
d)
In severe applications, shields should be tied directly to the
ground block within the panel.
e)
Ungrounded thermocouple sensors are preferred due to their
isolated electrical characteristics.
f)
Interposing terminal strips between the sensor and the module
can cause errors due to cold-junction effect.
g)
If interposing terminal strips must be used, use specially
constructed terminal blocks that match the material
characteristics of the thermocouple sensor.
h)
Horner thermocouple input modules use a high impedance
differential circuit to support the use of grounded or ungrounded
thermocouples. For grounded thermocouples, the specified
Common Mode Range
allows for ground potential differences
between the machine ground and the PLC ground within that
range. For ungrounded or floating thermocouples, the high
impedance inputs are subject to common mode noise pickup.
For noisy environments, it is recommended that one side of all
ungrounded thermocouples be grounded near the PLC. This
does not affect open thermocouple detection or measurement
accuracy and reduces the effect of common mode noise if
present. This PLC side ground connection must not be used
with grounded thermocouples or accuracy will be affected. Any
thermocouple should be grounded in one place at most.
When found on the product, the following symbols specify:
All applicable codes and standards need to be followed in the installation of this product.
For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or larger.
Adhere to the following safety precautions whenever any type of connection is made to the module.
Connect the green safety (earth) ground first before making any other
connections.
When connecting to electric circuits or pulse-initiating equipment, open their
related breakers. Do not make connections to live power lines.
Make connections to the module first; then connect to the circuit to be
monitored.
Route power wires in a safe manner in accordance with good practice and
local codes.
Wear proper personal protective equipment including safety glasses and
insulated gloves when making connections to power circuits.
Ensure hands, shoes, and floors are dry before making any connection to a
power line.
Make sure the unit is turned OFF before making connection to terminals.
Make sure all circuits are de-energized before making connections.
Before each use, inspect all cables for breaks or cracks in the insulation.
Replace immediately if defective.

WARNING:
Consult user documentation
.
WARNING:
Electrical Shock Hazard.
WARNING:
To avoid the risk of electric shock or burns, always connect the safety (or earth) ground before making any other connections.
WARNING:
To reduce the risk of fire, electrical shock, or physical injury it is strongly recommended to fuse the voltage measurement inputs. Be sure to locate
fuses as close to the source as possible.
WARNING:
Replace fuse with the same type and rating to provide protection against risk of fire and shock hazards.
WARNING:
In the event of repeated failure, do not replace the fuse again as a repeated failure indicates a defective condition that will not clear by replacing the
fuse.
WARNING:
Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should install, adjust,
operate, or service this equipment. Read and understand this manual and other applicable manuals in their entirety before proceeding. Failure to observe this
precaution could result in severe bodily injury or loss of life.
