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 be-
come 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 installed without a power
stage set. The mounting bracket should be protected from dirt and moisture during in-
stallation.
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 20 A.
► Connect the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, taking
care to ensure that the polarity is correct.
NOTE! If solar modules are grounded by a built-in grounding protection device in the in-
verter, they will not be grounded if the DC main switch is in the OFF position.
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 spec-
ified 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 invert-
er.
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 national guidelines.
