Grid connected inverter
Safety
| WARNING! Incorrect operation or poorly executed work can cause serious
injury or damage.
Only qualified staff are authorized to commission your inverter and only
within the scope of the respective technical regulations. Read the safety
rules before commissioning the equipment or carrying out maintenance work.
---|---
| WARNING! An electric shock can be fatal. Danger due to grid voltage and DC
voltage from
solar modules that are exposed to light.
– Ensure that both the AC side and the DC side of the inverter are de-
energized before carrying out any connection work. – Only an authorized
electrical engineer is permitted to connect this equipment to the public grid.
| WARNING! An electric shock can be fatal. Danger due to grid voltage and
DC voltage from solar modules.
– The DC main switch is only to be used to de-energize the power stage set.
The connection area is still live when the DC main switch is switched off.
– Ensure that the power stage set and connection area are disconnected from
one another before carrying out any maintenance or service tasks.
– The power stage set, which is enclosed in a separate housing, must only be
disconnected from the connection area when in a de-energized state.
– Maintenance and servicing in the power stage set of the inverter must only
be carried out by Fronius-trained service technicians.
| WARNING! An electric shock can be fatal. Danger due to residual voltage
in capacitors. Wait for the capacitors to discharge. The discharge time is
five minutes.
| WARNING! An inadequate ground conductor connection can cause serious injury
or damage. 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! Risk of damage to the inverter from dirt or water on the terminals
and contacts of the connection area.
– When drilling, ensure that terminals and contacts in the connection area do
not become dirty or wet.
– Without a power stage set, the mounting bracket does not conform to the
protection class of the inverter as a whole and so must not be installed
without the power stage set. The mounting bracket should be protected from
dirt and moisture during installation.
| CAUTION! Risk of damage to the inverter as the result of incorrectly
tightened terminals. Incorrectly tightened terminals can cause heat damage to
the inverter that may result in a fire. When connecting AC and DC cables,
ensure that all the terminals are tightened to the specified torque.
| CAUTION! Risk of damage to the inverter from overload.
– The maximum amperage when connecting to a single DC terminal is 32 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.
– The maximum DC input voltage must not exceed 1000 V DC.
| Fire prevention
CAUTION! Risk of damage to inverters and other live photovoltaic system
components due to poor or unprofessional installation. Poor or unprofessional
installation can cause overheating of cables and terminal connections and
result in arcs. These can cause heat damage, which in turn may lead to fires.
Observe the following when connecting AC and DC cables: – Tighten all
terminals to the torque specified in the Operating Instructions – Tighten all
grounding terminals (PE / GND), including free ones, to the torque specified
in the Operating Instructions – Do not overload cables – Check cables for
damage and verify that they are laid correctly – Take note of the safety
instructions, Operating Instructions and any local connection regulations
Using fastening screws, always screw the inverter firmly to the mounting
bracket to the torque specified in the Operating Instructions. Ensure that the
fastening screws are tight before starting the inverter!
---|---
| NOTE! Protection class IP65 is only applicable if the inverter is
permanently attached to the mounting bracket with screws.
Protection class IP20 applies to the mounting bracket with no inverter or
venting duct.
| 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! If the cable insulation of the AC cable is not designed for a
maximum of 1000 V, AC and DC cables must not be crossed when connecting to the
inverter. If crossing the cables during connection is unavoidable, the AC
cable must be laid in one piece of the protective hose supplied with the
inverter. AC and DC cables can only be laid together if the insulation on both
cables is designed for the max. the possible voltage of 1000 V.
Observe the manufacturer’s connection, Installation, and Operating
Instructions at all times. To reduce the hazard potential to a minimum,
perform all installation and connection work carefully according to the
instructions and regulations.
Refer to the device Operating Instructions / Installation Instructions for the
tightening torques to be used at the relevant terminal connections.

Tightly sealing the conduits
Ensure that the conduits are tightly sealed.
Seal Conduits
HINWEIS!
Condensation within the conduits can damage the inverter or components of the
photovoltaic systems. To avoid undesirable air circulation and condensation in
the conduits,
► seal all conduits being used with a permanently elastic sealant,
► seal every incoming and outgoing conduit,
► seal both conduit ends.
