CAUTION

• Failure to observe and follow the instructions provided in the equipment manual(s)  could cause irreversible damage to the equipment and could lead to property  damage, personal injury and/or death.  

• Before attempting to use the equipment, it is important that all danger and  caution indicators are reviewed.  

• If the equipment is used in a manner not specified by the manufacturer or  functions abnormally, proceed with caution. Otherwise, the protection provided by  the equipment may be impaired and can result in Impaired operation and injury. 

• Caution: Hazardous voltages can cause shock, burns or death. 

• Installation/service personnel must be familiar with general device test practices,  electrical awareness and safety precautions must be followed.  

• Before performing visual inspections, tests, or periodic maintenance on this device  or associated circuits, isolate or disconnect all hazardous live circuits and sources  of electric power.  

• Failure to shut equipment off prior to removing the power connections could  expose you to dangerous voltages causing injury or death.  

• All recommended equipment that should be grounded and must have a reliable  and un-compromised grounding path for safety purposes, protection against  electromagnetic interference and proper device operation. 

• Equipment grounds should be bonded together and connected to the facility’s  main ground system for primary power. 

• Keep all ground leads as short as possible.  

• At all times, equipment ground terminal must be grounded during device  operation and service.
