ARTS
A sufficient amount of stocked parts minimizes
service interruptions caused by breakdowns
and saves time and expense. When continuous
operation is a primary consideration a larger
quantity of renewal parts should be stocked
depending on the severity of the service and
the time required to secure replacement parts.
Since parts may be improved periodically,
renewal parts may not be identical to the
original parts. The recommended quantity is
not specified. This must be determined by the
user based on the application.
Powell recommends that only qualified persons
perform maintenance on these units. Refer
to the Qualified Person Section in the front of
this instruction bulletin. If these ground and
test devices are installed in a location where
they are not maintained by a qualified person,
a spare ground and test device should be on
site ready replacement. The malfunctioning
unit can then be returned to the factory for
reconditioning.
