Typical wiring diagram

It is the responsibility of the installer to verify compliance with all local and national codes.

Be certain to use UL approved wire with a voltage rating appropriate for your installation.

600 Volt wire for 600 Volt systems and 1 000 Volt wire for 1 000 volt systems.

Do not exceed 1 000 Volts.

This enclosure is not a disconnect. The disconnect must be rated for the voltage and current

applied to this transition box. The disconnect must break both PV+ and PV- on ungrounded

PV arrays. The disconnect should be located next to the inverter.

CAUTION:

On any installation that exceeds 750 Volts the installer is required to mark adjacent to each wiring compartment
