WARNING:
All electrical installations shall be done in accordance with all local
electrical codes and the National Electrical Code (NEC) (Canadian Electrical Code),
ANSI/NFPA 70.
The negative DC, Photovoltaic connection is grounded within the inverter through the
ground fault detection and interrupt circuit (GFDI). The PV negative should not be
grounded at any other point in the system. The PV positive must never be grounded
at any time. (Note that these instructions are reversed for optional positive grounded
versions of the inverter.)
When conduit hubs are used on the AC and DC disconnect boxes in an outdoor or wet
location, rain-tight or wet location hubs that comply with the requirements in the
Standard For Fittings For Conduit and Outlet Boxes, UL514B, are to be used.
For the 3-phase AC wiring, use 6 AWG, (recommended for the 208VAC version of
the 13 and 15kW) minimum 90
o
C (194
o
F), copper wire for connection with the
inverter’s 3-phase AC disconnect. (8 AWG recommended minimum for the 480VAC
versions of the 13-15kW and the 208VAC 10kW version, 10 AWG for all 600VAC
versions.) (Disconnect terminals listed for 75
o
C wire. See NEC 310.10 regarding
temperature ratings of wire.) Torque terminal screws to 45-50 in-lb. Voltage drop
and other considerations may dictate that larger wire sizes be used. (A maximum of 2
