6.6 DC Connection
DANGER
High voltages on PV modules that are exposed to light
Risk of death due to electric shock from touching a DC conductor.
• Do not touch the DC conductor.
High voltages in the DC cables
Risk of death or serious injury from touching a DC cable.
• Only connect the DC cable from the PV module to the inverter as described in this
manual.
NOTICE
Potential damage to the inverter due to overvoltage.
• The DC input voltage of the PV modules must not exceed the maximum values of the
inverter. Observe the information on the type label.
• Check the polarity and the open-circuit voltage of the PV strings before connecting
the DC cables to the inverter.
• Configure the DC input voltage range accordingly before connecting the PV modules
to the inverter. Use "Sunny Design" on www.SMA-America.com for string
configuration.
