CAUTION
Risk of burns due to hot enclosure parts
The enclosure and the enclosure lid may get hot
during operation. The DC load-break switch can
not become hot.
• Do not touch hot surfaces.
• Wait until the inverter has cooled down
before touching the enclosure or enclosure
lid.
CAUTION
Risk of injury due to weight of product
Injuries may result if the product is lifted incorrectly
or dropped while being transported or mounted.
• Carry and lift the product upright with the
help of several people. Take the weight and
the center of gravity of the product into
account. The center of gravity is on the side
of the AC-Connection Unit.
• Wear suitable personal protective equipment
for all work on the product.
• Transport the product using the carrying
handles or hoist. Take the weight of the
product into account.

NOTICE
High costs due to inappropriate Internet
tariff
Depending on use, the data volume of the product
transferred via the Internet may vary in size. The
data volume depends, for example, on the number
of devices in the system, the frequency of device
