When found on the product, the following symbols specify:

























For detailed installation and a handy checklist that covers panel box layout requirements and
minimum clearances, refer to the hardware manual of the controller you are using. (See the
Additional References section in this document.)

• 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 8917, 16 AWG

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

Warning: Electrical Shock Hazard.

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.

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.
