DANGER
2
PV solar arrays produce hazardous voltages and currents when exposed to light, which
can create an electrical shock hazard. Use dark opaque sheets to cover the PV solar
array before wiring or connecting cable terminations.
WARNING
Read all of these instructions, cautions, and warnings for the inverter and associated PV array.
WARNING
Installation and commissioning must be performed by a licensed electrician in accordance with
local, state, and National Electrical Code ANSI/NFPA 70 requirements. Use 10 AWG or greater
90°C (194 °F), copper solid or stranded wire for all DC and AC wiring to the inverter to optimize
system efficiency .
WARNING
Before connecting the inverter to the AC distribution grid, approval must be received by
appropriate local utility as required by national and state interconnection regulations. The inverter
must be connected only by qualified personnel.
CAUTION
Do not attempt to open or repair the inverter, as it is factory sealed to maintain Type 4 rating.
Opening the inverter will void the warranty.
CAUTION
The PV input circuits are isolated from the enclosure. The PV system Grounding Electrode
Conductor (GEC) when required by National Electric Code (NEC), ANSI/NFPA 70 Sections 690.41,
690.42, and 690.43 is the responsibility of the installer.
