SYSTEM GROUNDING
CAUTION
SYSTEM GROUNDING
·  SPD must be installed on solidly grounded power systems.  
·  Verify that the service entrance equipment is bonded to ground in  
  accordance with all applicable codes.  
·  Verify that the neutral terminals are grounded to system ground in  
  accordance with all applicable codes. 
Failure to follow these instructions can result in equipment 
damage.
An equipment ground conductor must be used on all electrical circuits 
connected to the SPD. For the best performance, use a single-point 
ground system where the service entrance grounding electrode system 
is connected to and bonded to all other available electrodes, building 
steel, metal water pipes, driven rods, etc. (for reference, see IEEE STD 
142-1991). The ground impedance measurement of the electrical system 
should be as low as possible, and in compliance with all applicable 
codes, for  electronics and computer systems. 
When metallic raceway is used as an additional grounding conductor, 
an insulated grounding conductor should be run inside the raceway and 
sized in accordance with all applicable codes.
 
WARNING
INADEQUATE RACEWAY ELECTRICAL CONTINUITY  
·  Ground impedance must be as low as possible and in compliance with  
  all applicable codes for electronic and computer systems.  
·  Install an insulated grounding conductor inside a metallic raceway when  
  the raceway is used as an additional grounding conductor. Size the  
  conductor in accordance with all applicable codes.  
·   Maintain adequate electrical continuity at all raceway connections.  
·   Do not use isolating bushings to interrupt a metallic raceway run.  
·   Do not use a separate isolated ground for the SPD.  
·  Verify proper equipment connections to the grounding system.  
·  Verify ground grid continuity by inspections and testing as part of a  
  comprehensive electrical maintenance program. 
Failure to follow these instructions can result in death or  
serious injury.
