PREPARING FOR TEST
IMPORTANT SAFETY WARNINGS
F
WARNING
The surge return is isolated from chassis ground by a 2000ohm
resistor. This limits current in the case of a failed concentric neutral.
The surge return cannot be used as a substitute system ground.
Failure to follow this procedure can result in serious injury
or in the extreme, death of the operator and/or the destruction of the
equipment.
F
WARNING
The operator is isolated from transient voltages along the surge
return by the insulation system in the PFL and by the insulated
jacket of the high voltage output cable. Tears or breaks in the
insulating jacket of the High-Voltage output cable expose the Surge
Return to the operator and poses a safety hazard and the cable
should be replaced.
F
WARNING
DO NOT EXTEND the Surge Return lead of the HV Output Cable
because this introduces excessive impedance in the Surge Return
and could result in exposed hazardous voltages.
