▶
Mount the product onto the mounting plate from above,
as shown in the figure.
▶
Make sure that you hear the product engaging in the
mounting plate (latching lug on the rear engages in lock-
ing plate (1)).
Condition: The load-bearing capacity of the wall is not sufficient
▶
If required, ensure that mounting apparatus on-site has
sufficient load-bearing capacity.
▶
Use individual stands or primary walling, for example.
▶
Wall-mount the product as described.

taic installation are taken into consideration.
Observe the wiring diagram in the → Appendix.
2.
5.2
Observing the requirements for the
photovoltaic modules
1.
Observe the installation instructions for the photovoltaic
modules.
2.
Use only photovoltaic modules whose connections do
not have to be earthed.
3.
Use only photovoltaic modules that comply with the
requirements of Class A in accordance with IEC 61730.
4.

0020273427_02 VPV I Installation and maintenance instructions
Condition: The maximum alternating current operating voltage is greater
than the nominal system voltage of the PV generator.
1
▶
Ensure that the maximum nominal system voltage of the
PV generator is higher than the alternating current mains
voltage.
5.3
Observing the requirements from the power
supply company
1.
Ensure that all of the requirements from the power sup-
ply company have been complied with before start-up.
2.
Ask the power supply company about any contractual
or country-specific requirements regarding operating
the inverter.

Installing the circuit breaker
1.
The circuit breaker may be dimensioned differently de-
pending on how the supply line is laid. If required, install
a circuit breaker in the household power network in ac-
cordance with the following table.
Inverter
VPV I 1500/2 230V
VPV I 2000/2 230V
VPV I 2500/2 230V
VPV I 3000/2 230V
VPV I 4000/2 230V
2.
If it is stipulated for the installation site, install a type-A
residual-current circuit breaker.
3.
Make sure that access to the power supply is always
available and is not covered or blocked.
4.
Inform the end user about the function and operation of
the circuit breakers.
