5.2 ELECTRICAL INSTALLATION, cont.
5.2.3 Grounding
The converter chassis ground MUST be connected to the ship’s hull or common ground point via
the compression fitting terminal adjacent to the output power connections. Failure to do so may
create conditions that may in turn cause injury or death to operators; failure to do so will also result
in the voiding of the equipment warranty. In the case of paralleled converter systems, and where
such ground connections are not local and directly adjacent to the paralleled converters, the chassis
ground connections must be interconnected between the paralleled converters as well as connected
to the remote ship’s common ground point.
THE CONVERTER ISOLATES THE OUTPUT POWER FROM THE INPUT POWER
AND EQUIPMENT (SAFETY) GROUNDS SIMILAR TO AN ISOLATION
TRANSFORMER. THE INSTALLER MUST RE-ESTABLISH THE GROUND
REFERENCE FOR THE EQUIPMENT AT TIME OF INSTALLATION. NEUTRAL AND
EQUIPMENT (SAFETY) GROUNDS TO BE CONNECTED PER THE APPROPRIATE
