AN OVERVIEW
This manual provides the operating and maintenance procedures for the Mark II series Foxcart Ground
Power Units. The first part of this manual covers operating procedures that are typical for aircraft
Ground Power Units operating from an alternating current source. Preparation for use and routine
maintenance are also covered. The second part is addressed to trained technical personnel qualified
to perform the detailed process of electrical configuration, problem analysis and repair. Applicable
drawings, charts and schematic wiring diagrams are provided and referenced in the text to identify
components and test points with typical voltage and resistance measurements. Due to the potentially
lethal voltages, it is mandatory that the units described herein be operated and maintained by prop-
erly trained and qualified personnel only.
NOTE
:
The Foxcart is designed to meet Underwriter’s requirements of safety, utility and plac-
ards, even though “UL” specifications are not directed to this type of device.
