Safety EN-US
WARNING! Incorrect operation and incorrectly performed work can cause serious injury and damage to
property. Only qualified staff are authorized to commission your inverter and only within the scope of the
respective technical regulations. Do not start up or carry out maintenance work until you have read the
safety rules.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC voltage from solar modules
that are exposed to light.
-
Prior to all connection work, disconnect the AC and DC supply to the inverter.
-
Only an authorized electrician is permitted to connect this inverter to the public grid.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC voltage from solar modules.
-
The DC main switch is used only to switch off power to the power stage set. When the DC main
switch is turned off, the connection area is still energized.
-
All maintenance and service work should only be carried out when the power stage set has been
disconnected from the connection area.
-
The separate power stage set area should only be disconnected from the connection area after first
being disconnected from the grid power.
-
Maintenance and service work on the inverter power stage set should only be carried out by Froni-
us-trained service technicians.
WARNING! An electric shock can be fatal. Inadequately sized electrical components can cause serious
injury and damage to property.
-
All electrical connections must be made in accordance with the National Electrical Code, ANSI/
NFPA 70, and any other regulations applicable to the installation site.
-
Installations in Canada must be carried out in accordance with applicable Canadian standards.
-
Use min. 194°F (90°C) copper wire for all grounding wires (see NEC table 250.122).
-
Voltage drop and other considerations may mean larger cable cross sections need to be used.
-
Use only solid or stranded wire. Do not use fine stranded wire.
WARNING! An electric shock can be fatal. Danger from residual voltage from capacitors.
You must wait until the capacitors have discharged. Discharge takes five minutes.
WARNING! An inadequate ground conductor connection can cause serious injury and damage to pro-
perty. The housing screws provide an adequate ground conductor connection for grounding the housing
and should not be replaced under any circumstances by other screws that do not provide a reliable
ground conductor connection.
WARNING! Work performed incorrectly can cause serious injury and damage. The overvoltage protec-
tion should only be installed and connected by licensed electricians. Follow the safety rules! Before any
installation or connection work is carried out, disconnect the AC and DC supply to the inverter.
CAUTION! The inverter can be damaged by soiling or water on the terminals and contacts in the connec-
tion area.
-
When drilling, make sure that terminals and contacts in the connection area do not become soiled
or wet.
-
The wall bracket without the power stage set does not possess the same degree of protection as
the complete inverter and, therefore, should not be attached without a power stage set.
Protect the wall bracket from soiling and moisture during installation.
CAUTION! Danger of damaging the inverter due to improperly connected terminals. Improperly connec-
ted terminals can cause thermal damage to the inverter and may cause a fire. When connecting the AC
and DC cables, make sure that all terminals are tightened securely using the proper torque.
CAUTION! Overloading the inverter may damage it.
-
Observe the maximum current carrying capacity of the various power categories (see Table A).
-
Only connect a maximum of 33 A to each DC terminal.
-
Connect the DC+ and DC- cables to the correct DC+ and DC- terminals on the inverter.
-
Observe the maximum DC input voltage.
