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 floor 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 power.  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.
