 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: 
  Connect the  safety (earth)  ground on  the power  connector 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. 
• Use Copper Conductors in Field Wiring Only, 60/75° C 
This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D or Non-hazardous 
locations only 
WARNING – EXPLOSION HAZARD – Do not disconnect equipment unless power has been 
switched off or the area is known to be non-hazardous. 
AVERTISSEMENT - RISQUE D'EXPLOSION - AVANT DE DECONNECTOR L'EQUIPMENT, 
COUPER LE COURANT OU S'ASSURER QUE L'EMPLACEMENT EST DESIGNE NON 
DANGEREUX.
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 – EXPLOSION HAZARD – Substitution of components may impair suitability for 
Class I, Division 2 
AVERTISSEMENT - RISQUE D'EXPLOSION - LA SUBSTITUTION DE COMPOSANTS PEUT 
RENDRE CE MATERIAL INACCEPTABLE POUR LES EMPLACEMENTS DE CLASSE 1, 
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 ONLY BE CHANGED IN AN AREA 
KNOWN TO BE NON-HAZARDOUS 
AVERTISSEMENT - RISQUE D'EXPLOSION - AFIN D'EVITER TOUT RISQUE D'EXPLOSION, 
S'ASSURER QUE L'EMPLACEMENT EST DESIGNE NON DANGEREUX AVANT DE 
CHANGER LA BATTERIE
WARNING -
 Battery May Explode If Mistreated. Do Not Recharge, Disassemble or Dispose Of 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 manuals in their entirety before 
proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.
