ELECTRICAL INSTALLATION, cont.
5.2.2 Output Power Connections
Each system is supplied with compression type terminal blocks for output power connections
(CONVERTER POWER). These terminal blocks accept wires in the range of 8 to 2/0 AWG.
Refer to the applicable class standard for selection of the required wire gauge and type.
Single-phase output configured systems (e.g. 220VAC): connect between the L1 and L2 output
terminals. When grounding this output power form, the L2 terminal must be used. Split-phase
output configured systems (e.g. 120/240VAC): use the L1, N (neutral), and L2 output terminals.
When grounding this output power form, the N (neutral) terminal must be used.
5.2.3 Grounding
The converter chassis ground MUST be connected to the ship’s hull or common ground point via
the ground stud terminal located between the input and 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
