WARNING!
Use #10 AWG, 105 °C, copper wire for all DC wiring connections to the
Digiwatts.
Voltage drop and other considerations may dictate that larger size
wires be used. Use only solid or stranded wire but not fine stranded wire.
WARNING!
The DC disconnect for the inverter must have a minimum rating of 600VDC
and 36A continuous.
Information
Series fusing may be required depending on the type of PV module used in the
system. See NEC 690.9.
WARNING!
You must connect the wires that carry the DC voltage from the PV array to
the Digiwatts unit in the order described in the following procedure.
Deviating
from this procedure could expose you to lethal voltages that can cause
serious injury and/or death.
WARNING!
PV arrays are energized when exposed to light. Use safe working practices
when working on PV arrays.
WARNING!
Always turn OFF all AC and DC breakers and switches in the PV system and
wait a minimum of 15 minutes for the Digiwatts unit to completely discharge
before connecting any wires to the Digiwatts unit or disconnecting any wires
from the Digiwatts unit.
Failure to do so could expose you to lethal voltages
that can cause serious injury and/or death.
