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.

5.2.4 Multi-Cabinet Connections
Multi-cabinet systems should have each cabinet’s output connections paralleled at the switchgear
panel. The converters’ terminal blocks are sized for a single, appropriated sized cable per phase,
neutral, and grounding conductor.
Multi-cabinet systems are constructed from one cabinet which serves as the system Master, and an
additional cabinet(s) which serves as the Slave(s). A paralleling cable assembly (
P/N 605150
) is
shipped pre-connected to the Slave cabinet and coiled at the base of the cabinet near the Input and
Output connection terminal blocks. It must be connected to the interface connector at the base of
the Master cabinet (see Figure 6 on page 21). Do not substitute cable assemblies. If a longer
cable is needed for a given installation, contact the factory for the appropriate cable.
