CHAPTER 1: SAFETY / COMPLIANCE
1.1 Safety Warnings and Guidelines
When found on the product, the following symbols specify:
a. All applicable codes and standards need to be followed in the installation of this product.
b. For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or larger.
Warning – Consult user documentation.
Warning – Electrical Shock Hazard.
WARNING – EXPLOSION HAZARD – Do not disconnect equipment unless power has been switched off or
the area is known to be non
-hazardous.
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 vo
ltage 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
– EXPLOSION HAZARD – Substitution of components may impair suitability for Class I,
Division 2.
WARNING
- The USB parts are for operational maintenance only. Do not leave permanently connected
unless area is known to be non
-hazardous.
WARNING
– EXPLOSION HAZARD - BATTERIES MUST NOT BE CHANGED.
WARNING
– BATTERY MAY EXPLODE IF MISTREATED. DO NOT RECHARGE, DISSASSEMBLE, OR DISPOSE
IN FIRE.
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 manual in their entirety before proceeding. Failure to
observe this precaution could result in severe bodily injury or loss of life.

Adhere to the following safety precautions whenever any type of connection is made to the module.
a. Connect the green safety (earth) ground first before making any other connections.
b. When connecting to electric circuits or pulse-initiating equipment, open their related breakers.
Do not make connections to live power lines.
c. Make connections to the module first; then connect to the circuit to be monitored.
d. Route power wires in a safe manner in accordance with good practice and local codes.
e. Wear proper personal protective equipment including safety glasses and insulated gloves when
making connections to power circuits.
f. Ensure hands, shoes, and floors are dry before making any connection to a power line.
g. Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits
are de-energized before making connections.
h. Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if
defective.
