3.4.3 FIELD GROUND HIGH-VOLTAGE PROTECTION SYSTEM
The field ground high-voltage protection system consists of two modules: the field ground protection high-voltage module
(GPM-F-HM) and the field ground protection high-voltage resistor box (GPM-F-R). The following figures show the mounting
and dimensions (all dimensions are in inches).
