5.2 ELECTRICAL INSTALLATION
This procedure assumes the physical installation of the converter has been completed.
It is the installer’s responsibility to provide input service over-current protection and a
disconnect means.
It is recommended that connection be made to the distribution bus through a manually operated
disconnect device such as a molded case switch or circuit breaker (rated for the total system
amperage) to ease disconnection and provide a safe servicing environment in the event of
converter failure.
Follow the table below for shore power wiring.

All power wiring requires the removal of the front panel and the power cable access cover
(cabinet bottom). This cover is secured with 2 ea 1/4-20" x ½" stainless steel screws. Drill or
punch the appropriate holes for the selected strain reliefs. Re-install the input service panel using
the removed hardware. Place the disconnect switch in the OFF position.
