5.11.3 Connecting PV

Danger to life due to electric shock when live
components or DC cables are touched
When exposed to light, the PV modules generate
high DC voltage which is present in the DC cables.
Touching live DC cables results in death or lethal
injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the inverter from voltage sources
and make sure it cannot be reconnected before
working on the device.
• Wear suitable personal protective equipment
for all work on the product.
Danger to life by electric arc when there is a
reverse-poled connection of the DC cables
A reverse-poled connection of the DC cables can
cause an electric arc. Electric arcs can result in
death or serious injury.
• Ensure that the polarity of the DC cables is
correct prior to connection.
Damage to the inverter due to reverse
polarity.
The inverter is protected against short-term reverse
polarity. Not correcting reverse polarity might
cause high electric currents. This results in
irreparable defects of the inverter and will void the
warranty.
• Make sure that the cables are properly
connected to the inverter so that the inverter
can feed in DC input voltage.
The combined power from the PV array junction box
must be connected to the DC input of the inverter.
The DC power can be disconnected with the
inverter-integrated DC load-break switch.
