Grid Output Connection (Ac Side); Connection To Ac Terminal Block - ABB UNO-DM-TL-PLUS-US Product Manual

G
rid output connection (AC side)
Wire must be sized based on ampacity requirements of the NEC or other applicable prevail-
ing code.
To prevent electrocution hazards, all the connection operations must be carried out with the
external AC disconnect switch downstream of the inverter (grid side) open and locked out.
Any failure of the inverter when it is not connected to ground through the appropriate terminal
is not covered by the warranty.
C
onnection to AC terminal block
Conduit must be sealed using water-tight fittings to maintain NEMA Type 4X enclosure integrity.
CAUTION
This is a single phase inverter. Use the wiring schemes shown on the
table below when a different grid standard is used. Refer to the
instruction manual to properly set the inverter grid standard from the
front panel display. Use 90°C copper wire only. Refer to the instruction
manual for wiring instructions.

- Run an approved raceway between inverter and external AC OCPD.
- Remove the threaded plastic plug and nut from the AC cable opening
- Insert the appropriate water-tight conduit connector and tighten to the
chassis to maintain NEMA 4X compliance.
- Make appropriate conduit runs from grid and pull the AC conductors
through the raceway to the inverter.
- Connect the conductors to the correct terminals on the
