General information
DANGER
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
Installation and commissioning must be performed by a licensed electrician in accordance with
local, state, and National Electrical Code ANSI/NFPA 70 requirements.
WARNING
Inputs and output circuits of this unit are isolated from the enclosure. System grounding must be
done in accordance with the National Electrical Code (NEC), ANSI/NFPA 70 and Compliance is the
responsibility of the installer.
WARNING
Ensure no live voltages are present on PV input and AC output circuits, and verify that the DC
disconnect, AC disconnect, and dedicated AC branch circuit breaker are in the [OFF] position,
before inverter installation.
WARNING
Inverter warranty is VOID if the DC input voltage exceeds the inverter 450 V DC maximum.
WARNING
Power fed from more than one source, more than one live circuit. Please note that all DC and AC
terminals may carry current even without connected wires.
CAUTION
The inverter must be permanently mounted before any electrical wiring can be connected to the
inverter.
