WARNING!
Danger from inadequate ground conductor connection.
This can result in serious injury and damage to property.
▶
The housing screws provide a suitable ground conductor connection for
grounding the housing and must NOT be replaced by any other screws that
do not provide a reliable ground conductor connection.
CAUTION!
Danger due to dirt or water on the terminals and contacts of the connection
area.
This may result in damage to the inverter.
▶
When drilling, ensure that terminals and contacts in the connection area do
not become dirty or wet.
▶
The mounting bracket without a power stage set does not conform to the
protection class of the inverter as a whole, and therefore must not be in-
stalled without a power stage set. The mounting bracket should be protected
from dirt and moisture during installation.
CAUTION!
Danger due to incorrectly tightened terminals.
This may result in heat damage to the inverter, which may lead to fire.
▶
When connecting AC and DC cables, ensure that all the terminals are
tightened to the specified torque.
CAUTION!
Danger due to overloading.
This may result in damage to the inverter.
▶
The maximum amperage when connecting to a single DC terminal is 36 A.
▶
Connect the DC+ and DC- cables to the DC+ and DC- terminals on the in-
verter, taking care to ensure that the polarity is correct.
NOTE! If solar modules are grounded by a built-in grounding protection device in
the inverter, they will not be grounded if the DC main switch is in the OFF posi-
tion.
NOTE! When connecting aluminium cables:
-
Observe national and international guidelines regarding the connection of
aluminium cables
-
Follow the instructions of the cable manufacturer.
-
Check every year that the cables are securely attached in accordance with
the specified torque.
NOTE! The solar modules connected to the inverter must comply with the IEC
61730 Class A standard.
NOTE! When photovoltaic modules are exposed to light, they supply current to
the inverter.
NOTE! Ensure the polarity is correct when connecting the DC cables.
NOTE! For grounding solar module frames or racks, the relevant specifications
from the solar module manufacturer must be taken into account along with na-
tional guidelines.
