APC SurgeArrest PM 208/120V 80KA, Non-modular PMF2X-A Manuel D’Utilisation

An equipment grounding 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 142-2007). The 
ground impedance measurement of the electrical system should be as low 
as possible, and in compliance with all applicable codes, for sensitive 
electronics and computer systems.

When a 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.

• Must be installed on solidly grounded power systems. Do not use on 

ungrounded 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.

• Ground impedance must be as low as possible and in compliance with 

all applicable codes for sensitive 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.
