Precautions

All applicable codes and standards need to be followed in the installation

of this product. Adhere to the following safety precautions whenever any

type of connection is made to the module:

1. Connect the safety (earth) ground on the power connector first

before making any other connections.

2. When connecting to the electric circuits or pulse-initiating equipment,

open their related breakers.

3. Do NOT make connection to live power lines.

4. Make connections to the module first; then connect to the circuit to

be monitored.

5. Route power wires in a safe manner in accordance with good practice

and local codes.

6. Wear proper personal protective equipment including safety glasses

and insulated gloves when making connections to power circuits.

7. Ensure hands, shoes, and floor are dry before making any connection

to a power line.

8. Make sure the unit is turned OFF before making connection to terminals.

9. Make sure all circuits are de-energized before making connections.

10. Before each use, inspect all cables for breaks or cracks in the

insulation. Replace immediately if defective.

11. Use copper conductors in Field Wiring only, 60/75˚C.

12.  Use caution when connecting controllers to PCs via serial or USB.

PCs, especially laptops, may use “floating power supplies: that are

ungrounded.  This could cause a damaging voltage potential between

the laptop and controller.  Ensure the controller and laptop are

grounded for maximum protection. Consider using a USB isolator due

to voltage potential differences as a preventative measure.
