2.3 Hazards during handling and installation
2.3
Hazards during handling and installation
Improper handling and installation of certain parts and components can result in injury under
unfavorable conditions.
CAUTION
Danger of injury due to improper handling! Injury by crushing, jackknifing, cutting, bumping,
or lifting!
• The general construction and safety regulations must be observed in handling and
installation.
• Each cabinet section weighs more than 1,000 kg.
• Suitable installation and transport equipment must be used. Read the specifications and
safety information of the chapter Application planning (Page 81).
• Only use suitable tools.
• Lifting equipment and tools must be used correctly.
• Suitable protective equipment (e.g. safety goggles, safety shoes, protective gloves)
must be used.
• Never stand underneath suspended loads.
2.4
Hazards in photovoltaic plants
Below are listed some typical special features and hazard sources in photovoltaic plants:
● Since the short-circuit current only slightly exceeds the maximum operating current, there
is no clear guarantee that the available fuse will trip in the event of a short-circuit.
● Depending on the operating status, the plant can still be under power from the PV
generator via the SINVERT PVS inverter even when it is switched off. This must be
remembered when isolating the plant or sections of the plant.
● The PV generator is usually configured as an IT system without grounded transformer. A
ground fault generates a fault message. In an IT system, there is no immediate danger of
electric shock if no further fault occurs. Despite this, the ground fault must be corrected
as quickly as possible by qualified personnel.

2.5 Incorrect grid monitoring parameters
2.5
Incorrect grid monitoring parameters
NOTICE
Withdrawal of operating permit
If you operate the SINVERT PVS inverter with the wrong grid monitoring parameters, the
electrical utility can withdraw your operating permit.
The device must therefore only be commissioned by authorized service personnel. The
system settings must be adapted to local requirements regarding grid monitoring
parameters.
We assume no responsibility for incorrect grid monitoring parameters.
2.6
Possible safety gaps in the case of standard IT interfaces
In SINVERT inverters, extensive parameterization and diagnostics functions are provided via
open protocols and interfaces (e.g. Web server, network management). The possibility of
unauthorized misuse of these open protocols and interfaces by third parties, for example to
manipulate data, cannot be entirely excluded.
When using the functions listed above and these open interfaces and protocols (for example,
SNMP, OPC, HTTP), you should take suitable security measures to prevent unauthorized
access to the components and the network, particularly from within the WAN/Internet.
NOTICE
We expressly point out that the inverter network must be isolated from the rest of the
company network by suitable gateways (for example, field-proven firewall systems). We do
not accept any liability whatsoever, whatever the legal justification, for damage resulting
from non-adherence to this notice.
If you have questions on the use of firewall systems and IT security, please contact your
local Siemens office or representative.

3.3 Operating principle
3.3
Operating principle
The SINVERT PVS inverter works on the following functional principles:
● The inverters are based on SINAMICS (power unit with IGBT three-phase bridge) and
SIMOTION (controller).
● 3 inputs for connecting the PV array are provided at the PV array end.
Note
The PV array must be connected for this purpose in 3 sub-arrays with the same total
current and voltage values.
● The 3 inputs on the DC side are equipped with LV HRC fuses and DC contactors. This
combination can be used to disconnect the inverter from the PV side.
● AC filters are used to smooth the AC output voltage.
● The AC output must be connected directly to the medium-voltage transformer for galvanic
isolation. This is required at the AC output of every inverter subunit.
● A contactor and circuit breaker are used to disconnect the unit from the AC grid.
● Overvoltage protection devices are installed on the AC and DC sides.
● To increase efficiency and reduce no-load losses, up to four inverters can be
interconnected in master/slave operation.

3.5 Inverter options
3.5.1
PV array grounding
With the optional feature "Positive / Negative PV array Grounding", the SINVERT inverters
offer an ideal choice for manufacturers who require a module ground.
Remember: For the latest information about the necessity for and type of grounding, please
contact your module manufacturer!
Some module manufacturers recommend positive or negative grounding of the PV generator
when certain types of module are used!
PV systems no longer constitute a DC IT system when their modules are grounded. For
safety reasons, the PV system must be fenced in and designated as an electrical operating
area.
Access must be prohibited to all persons except qualified electricians.
Positive-pole grounding
Grounding an active conductor (positive pole) means that the inverter's insulation measuring
function no longer works in the normal way. A hazardous current can start to flow as soon as
the first insulation damage occurs. For this reason, the condition of the system is monitored
through measurement of the current between the positive pole and ground. If the current
level measured is deemed to pose a risk (current value is parameterizable), the connection
is automatically broken by means of a motor-operated DC disconnector. This DC
disconnector is driven by the inverter's control system. In this context, it is important to note
that the connection between the module array and inverter ground must be of high quality. If
the connection resistance is high as a result of very dry conditions or unfavorable ground
conditions, a sufficiently high current will not flow. It is also important to note that a fault at
the same potential when grounded will not drive a current.
The DC disconnector has three settings:
● Remote triggering
● Local operation
● "Off signal" position, lockable

3.5.2
Increase in max. DC voltage to 1000 V
Areas of application and use
The "1000 V option" increases the maximum DC no-load voltage for inverters to DC 1000 V.
This ensures that the photovoltaic system can also operate with a (no-load) voltage of up to
DC 1000 V, for example when operating on cold days. The profitability of the equipment is
maximized as more modules can be connected in series, without affecting the ability of the
PVS inverter to switch on.
When will the equipment operate at no load?
No-load operation will happen at the following times:
● Before switching on the PV inverter
● After switching off the PV inverter
Standard response of the PVS inverter without the "1000 V option"
The PV inverters of the PVS series feature a switch-on voltage of max. 820 V DC as
standard. If the DC voltage is above 820 V, the SINVERT PVS PV inverter will not switch on.
The 1000 V option allows the switching on and off of the SINVERT PVS PV inverter for PV
field no-load voltages of up to 1000 V DC.

Operating Instructions, 08/2014, A5E03467293-003
Description
3.5 Inverter options
Switching on the PV inverter with "1000 V option"
Switching on the PVS allows a variable voltage divider, consisting of series and parallel
resistors, to activate the inverter DC link (without closing the DC input contactors). Thus only
the required fraction of the PV field no-load voltage is present at the DC link, and not the
entire PV field no-load voltage. The upstream measurement of the PV field voltage (Upv) is
carried out in each individual inverter subunit. Only when the PVS SINAMICS power unit is
operating and the AC main contactor is closed do the DC power contactors close in
succession.
Switching off the PV inverter with "1000 V option"
When switching off the last (of max. four) PV inverter subunits in normal operation, the DC
power contactors are first opened in succession, before the SINAMICS power unit of the
inverter subunit is switched off and the AC contactor opened.
During normal operation this ensures that the PV field no-load voltage is not present at the
DC link.
Unintentional disconnection of the PV inverter with "1000 V option"
During operation of the PV inverter, situations may arise which lead to the PV inverter and
the power unit to be switched off unintentionally. In such cases it is not always possible to
successively or immediately switch off the DC power contactors prior to switching off the
power unit, or they are switched off too slowly, to prevent the DC link voltage rising to
impermissible values. In such cases, to protect the DC link against voltages which are too
high, the following components are used:
● 1000 V special chopper
● Chopper resistor
● Crowbar
3.5.3
Cabinet heating
Heating elements are integrated into the inverter to prevent condensation and if atmospheric
humidity is too high. These heating elements are controlled by a hygrostat.
3.5.4
Symmetry monitoring
The symmetry monitoring option measures the scaled currents within the inverter at the DC
inputs and compares the values with each other.
If this comparison indicates deviations over time, a message is generated. The message can
be used for early detection of faults in parts of the photovoltaic field (e.g. cell failure).

Active power control according to frequency P=f(f)
If the power grid contains more power than is currently used, the grid frequency increases.
The SINVERT PVS inverters detect an increase in the grid frequency and can reduce the
active power dependent on frequency.
The relationship between the output power and the grid frequency is predefined via the P(f)
curve.
If a parameterized frequency value f1 is exceeded, the active power Pf present at this time is
registered and thereafter used as the reference value for the P=f(f) curve.
While the frequency in the grid increases, the SINVERT PVS inverter supplies an output
power dependent on the level of the current frequency along the curve. The rise in the
PP=f(f) curve can be parameterized on the inverter by means of the gradient G.
If the frequency exceeds a parameterized frequency limit fH, see Chapter Frequency
monitoring (Page 74), the SINVERT PVS inverter switches off.

4.2 Static grid support
Resumption of normal operation:
There are three modes of resuming normal operation in the the case of frequency derating:
1. Frequency derating without hysteresis
Figure 4-6
Active power control according to frequency P=f(f) without hysteresis
As long as the frequency does not drop below the limit f1 again, the SINVERT PVS
inverter supplies an output power dependent on the level of the current frequency along
the curve. As soon as the frequency drops below the limit f1 in the grid, the SINVERT PVS
inverter resumes normal operation. It now feeds in the maximum possible power again,
provided no other specifications are present.
2. Frequency derating with hysteresis and start frequency
Figure 4-7
Active power control according to frequency P=f(f) with hysteresis and start
frequency
If a second limit frequency f2 (parameterizable) is exceeded, the inverter no longer follows
the curve, and instead remains at a constant output power Pf2(determined by the curve)
until the frequency has dropped below the end frequency for resuming normal operation
f3 (parameterizable).

3. Frequency derating with hysteresis and without start frequency
Figure 4-8
Active power control according to frequency P=f(f) with hysteresis and start
frequency
Contrary to active power control according to frequency P=f(f) with hysteresis and start
frequency, the second limit frequency f2 is not required. The inverter generally no longer
follows the curve in the case of frequency derating, and instead remains at the minimum
calculated output power P (determined via the curve) until the final frequency for
resuming normal operation f3 (parameterizable) has been undershot.
Only one mode is parameterized for frequency-dependent active power reduction. You set
all parameters here, regardless of which mode is used.
Parameterization of a minimum holding power
A minimum holding power can be parameterized additionally for modes 1 and 3. Some
Grid Codes demand this. If this function is activated, the inverter will not reduce the output
power below the parameterized holding power. If the frequency f nevertheless continues to
rise, the inverter will be switched off when the frequency point fH is reached.
Note
The functions can be deactivated if required.

4.2.1.4
Active power control during the switch-on operation
Function
To avoid sudden variations in active power on the grid resulting from fast switch-on of the PV
plant, the SINVERT PVS inverter can increase its output via a parameterizable ramp. The
following options can be parameterized to stipulate when the output is to be increased via a
ramp:
● Never
● Only following grid fault
● At every start operation
The increase of the ramp over a gradient until the full rated active power Pn is reached can
continue to be parameterized.
The increase in the ramp is independent of the actually present active power. The active
power increases along the ramp up to the existing PV array power.

Reactive power control
Methods of controlling the reactive power
The increasingly strong trend towards integration of distributed generating plants into
distribution grids results in the rising challenge of voltage stability. It is possible to influence
the grid voltage by means of the reactive power. The SINVERT PVS inverters can be
operated with a reactive power corresponding to a power factor cosφ = 0.8 inductive (low
voltage / medium voltage) to cos φ = 0.8 capacitive.
Note
Negative values correspond to an inductive reactive power (overexcited operation) and
positive values to a capacitive reactive power (underexcited operation).
Reactive power control can be specified in accordance with five different functions:
● Reactive power control to absolute setpoint of Q or cos φ
● Reactive power control according to time of day Q(t) or cos φ (t)
● Reactive power control according to output voltage Q=f(U)
● Reactive power control according to active power cos φ (P)
● Reactive power control to relative fixed setpoint of Qmax
In general, a distinction must be made between two different bases when providing reactive
power:
● Reactive power control on the basis of the power factor cos φ
● Reactive power control on the basis of reactive power Q
Different functions are available depending on the basis selected.
Reactive power control on the basis of the power factor cos φ
For power factor cos φ (setpoint type), you can select one of the following functions (setpoint
source):
● Fixed setpoint
● cos φ (P) curve
● cos φ (t) curve
Note

When using the SINVERT PVS ControlBox, the function "Fixed setpoint" must be selected

Behavior in the case of voltage dips (low voltage ride through)
Due to the growing spread of renewable energy forms, you must ensure that the inverter
does not shut down immediately when brief voltage dips occur. The SINVERT PVS inverter
has the ability to withstand brief voltage dips and remain on the grid. The shutdown behavior
in the case of voltage dips can be set via the LVRT curve, see the chapter "Shutdown
behavior in the event of voltage dips (Page 64)".
The SINVERT PVS inverter can continue to provide reactive current for voltage support
during these voltage dips. The level of the reactive current can be set via the k factor
depending on the depth of the grid voltage dip, see the chapter "Reactive current provision in
the event of voltage dips (Page 67)".
4.3.2
Function
Shutdown behavior in the event of voltage dips
The LVRT curve can be parameterized by means of up to 10 interpolation points. An
interpolation point consists of a voltage level U / Un and a time t during which the voltage
level can be present before the SINVERT PVS inverter shuts down. Linear interpolation is
carried out between the two interpolation points. The voltage level is calculated from the ratio
of the actual voltage U to the rated voltage Un.
Note
The function can be deactivated if required.
The limit curve shown in the figure represents a typical LVRT curve as defined by many grid
operators.

4.3 Dynamic grid support
Settings
Note the following points when parameterizing the LVRT curve:
● The parameterized LVRT curve must correspond to the undervoltage protection settings.
For this reason, parameterize two of the interpolation points identically to the entered limit
values of the undervoltage monitor.
See Chapter Voltage monitoring (Page 76).
● When parameterizing, all fields must be filled, but it is not absolutely necessary to use all
available interpolation points.
When using fewer than 10 interpolation points, the order of the entered interpolation is
decisive since interpolation between the individual points is linear. For this reason, always
enter the used interpolation points first. Then enter the values of the last interpolation
point in the subsequent fields for the interpolation points that are not required.
You will find an example in the figure below. The first four interpolation points (0 to 4) are
used. All the subsequent fields (5 to 9) for the unused interpolation points are
parameterized in the same way as the last interpolation point.

Reactive current provision in the event of voltage dips
Function
In the event of a voltage dip, the SINVERT PVS inverter can provide reactive current for
voltage stability.
The level of the reactive current ΔIB / In additionally fed in when a fault occurs results from
the depth of the grid voltage dip ΔU / Un and the k factor. No more than the rated current In
can be fed in. During the voltage dip, as much active power as possible continues to be fed
in.
In addition, the SINVERT PVS inverter has "Zero power mode". If this mode is set, the
SINVERT PVS inverter remains on the grid for the parameterized time but feeds neither
active nor reactive power into the grid.
"Q mode" is another mode. If this mode is set, the SINVERT PVS inverter remains on the
grid for the parameterized time and feeds pure reactive power into the grid.
In "Standard mode" as well as "Q mode", the reactive current response can be be set not
only via the k factor, but also via "Advanced mode". In this mode, it is possible to
parameterize a Q=f(U) characteristic freely for LVRT.

Behavior in the case of voltage rises (low voltage ride through)
Due to the growing spread of renewable energy forms, you must ensure that the inverter
does not shut down immediately when brief voltage rises occur. The SINVERT PVS inverter
has the ability to withstand brief voltage rises and remain on the grid. The shutdown behavior
in the case of voltage rises can be set via the HVRT curve, see the chapter "Shutdown
behavior in the event of voltage rises (Page 69)".
The SINVERT PVS inverter can continue to provide reactive current for voltage reduction
during these voltage rises. The level of the reactive current can be set via the k factor
depending on the extent of the grid voltage rise, see the chapter "Reactive current provision
in the event of voltage rises (Page 72)".
4.3.5
Shutdown behavior in the event of voltage rises
Function
The HVRT curve can be parameterized by means of up to 10 interpolation points. An
interpolation point consists of a voltage level U / Un and a time t during which the voltage
level can be present before the SINVERT PVS inverter shuts down. Linear interpolation is
carried out between the two interpolation points. The voltage level is calculated from the ratio
of the actual voltage U to the rated voltage Un.
Note
The function can be deactivated if required.
The limit curve shown in the figure represents a typical HVRT curve as defined by many grid
operators.

4.3 Dynamic grid support
Settings
Note the following points when parameterizing the HVRT curve:
● The parameterized HVRT curve must correspond to the undervoltage protection settings.
For this reason, parameterize two of the interpolation points identically to the entered limit
values of the overvoltage monitor.
See Chapter Voltage monitoring (Page 76).
● When parameterizing, all fields must be filled, but it is not absolutely necessary to use all
available interpolation points.
When using fewer than 10 interpolation points, the order of the entered interpolation is
decisive since interpolation between the individual points is linear. For this reason, always
enter the used interpolation points first. Then enter the values of the last interpolation
point in the subsequent fields for the interpolation points that are not required.
You will find an example in the figure below. The first four interpolation points (0 to 5) are
used. All the subsequent fields (6 to 9) for the unused interpolation points are
parameterized in the same way as the last interpolation point.

4.3.6
Reactive current provision in the event of voltage rises
Function
In the event of a voltage rise, the SINVERT PVS inverter can provide reactive current for
voltage reduction.
The level of the reactive current ΔIB / In additionally fed in when a fault occurs results from
the extent of the grid voltage rise ΔU / Un and the k factor. No more than the rated current In
can be fed in. During the voltage rise, as much active power as possible continues to be fed
in.
In addition, the SINVERT PVS inverter has "Zero power mode". If this mode is set, the
SINVERT PVS inverter remains on the grid for the parameterized time but feeds neither
active nor reactive power into the grid.
"Q mode" is another mode. If this mode is set, the SINVERT PVS inverter remains on the
grid for the parameterized time and feeds pure reactive power into the grid.
In "Standard mode" as well as "Q mode", the reactive current response can be be set not
only via the k factor, but also via "Advanced mode". In this mode, it is possible to
parameterize a Q=f(U) characteristic freely for HVRT.

Function
The SINVERT PVS inverter monitors the public energy grid for violations of adjustable grid
frequency and grid voltage limits. If the limits are violated for an adjustable time, the inverter
disconnects from the grid.
4.4.2
Frequency monitoring
Function
The SINVERT PVS inverter monitors the grid frequency during operation. If a certain
frequency range is exceeded or undershot, a grid fault can be assumed, and shutdown of
the SINVERT PVS inverter is necessary. Up to six parameterizable limits for both
overfrequency and underfrequency are available for shutdown outside the permissible
frequency range.
A frequency and a tripping delay time can be parameterized for each limit.
If the grid frequency is outside the parameterizable range, the SINVERT PVS inverter shuts
down, and a fault message is output.
As soon as the grid frequency returns to the permissible range, the fault message is
automatically acknowledged.
If the grid is within the specified limits for restarting, see the chapter "Feed-in conditions
(Page 79)", the inverter powers up again automatically.

The delay is the minimum time for which a fault must be active to effect shutdown. If the set
limit values are undershot or exceeded for the set time, the inverter switches off with an
appropriate fault message. Shutdown of the inverter takes approx. 80 ms.
The required limit values for overfrequency/underfrequency refer to the rated grid frequency
of the inverter.
When parameterizing, all fields must be filled, but it is not absolutely necessary to use all
available interpolation points.
When using fewer than the two available interpolation points, the sequential order of the

Feed-in conditions
In the event of a grid fault, connection of the inverter must be prevented. For this purpose,
the SINVERT PVS inverter monitors the grid with regard to frequency and voltage, and
switches on if the grid is within a parameterizable range.
One limit each is available to you for parameterizing the permissible frequency and voltage
range. If the grid is within the parameterized limits, and if all restart conditions have been
met, the inverter powers up again automatically.
The voltage limits are input as a percentage of the rated voltage; the frequency limits are
input as a percentage of the rated frequency (50 / 60 Hz).
Note
The connection conditions range must be smaller than the shutdown conditions range to
avoid the constant on and off switching of the inverter when operating in limit ranges of the
permissible rated voltage/frequency.
You will find further information on the shutdown conditions in the chapters "Frequency
monitoring (Page 74)" and "Voltage monitoring (Page 76)".

WARNING
Danger to life from transport of assembled cabinet sections!
Owing to their design, cabinet sections must never be transported once they have been
mechanically assembled into a single unit. Cabinet sections must always be transported as
a single unit by one of the permitted methods of transport. The heavy weight of the cabinets
means that they can cause serious injury, death and substantial property damage if
incorrectly handled.
Locking of the doors
The doors on the cabinet sections are closed by Siemens prior to dispatch. Keep these
doors closed and locked at all times during transportation.
The door locks are secured against accidental unlocking by means of small plastic caps. The
plastic caps must be removed when the consignment is positioned at the final installation
location.
CAUTION
Serious injury in the case of transporting with opened doors!
Open doors can hit people or other objects while a unit is being transported. They can
cause serious injury or property damage.
Keep the doors locked.

Procedure
Whether a load is transported by crane on an H beam or a specially designed frame
structure, it is always essential that the inverter is mechanically coupled to the pallet.
1. The crane ropes are placed under the load at a marked position in parallel to the side
wall.
2. They are then brought up in parallel to and at an appropriate distance from the straps,
from where they are threaded through a frame structure or attached to the H beam.

● Use of crane beams
● Prohibited attachment of ropes along vertical sides of load
Figure 5-9
Impermissible transport methods: Crane eyelets, crane beams, roping along vertical sides
Please note that other methods apart from those mentioned above are also prohibited if they
are not expressly approved by Siemens as a permissible method of transport.
WARNING
Danger to life from impermissible use of crane eyelets and steel lifting elements!
The inverter cabinets are not designed for transportation by crane on eyelets or steel lifting
elements. It is absolutely prohibited to transport the inverters on crane eyelets or steel lifting
elements. If excessive mechanical stress causes the load to fall off the crane, there is a risk
of serious injury, death or substantial property damage.
WARNING
Danger to life from impermissible attachment of ropes along vertical sides of load!
The cabinets are not designed to be transported by crane from ropes attached along the
vertical sides of the load. This method of transport is expressly prohibited. If excessive
mechanical stress causes the load to fall off the crane or to tip, there is a risk of serious
injury, death or substantial property damage.

Transport and alignment of cabinets in electrical operating areas
Removing the transport locks
The cabinets are attached to the pallet by means of transport locks (upward-facing screws).
1. To lift the cabinets off the pallet, you first need to undo the screw nuts.
2. To slide the cabinets off the pallet, you need to push the screws out downwards far
enough (e.g. using a hammer and a thick nail), so that the surface of the pallet becomes
smooth.
Moving the cabinet off the standard pallet
All cabinets can be moved on rollers placed under the cabinet frame. As rollers, you should
use solid metal rods with a length of 20 cm and a diameter of 2 cm.
Figure 5-10
Moving the cabinet off the standard pallet
● Use a crowbar to lift the cabinet so that you can place the rollers under the frame. If you
want to change the rolling direction, you must lift the cabinet again, turn the rollers by 90°
and place them under the frame again.
● You may need to strengthen the floor with metal sheets before you move the cabinets

7.4 Rapid stop function
7.4
Rapid stop function
The "rapid stop function" is used for fast shutdown of the AC grid in the event of faults.
Installation of a corresponding external switch with this function is therefore absolutely
necessary.
WARNING
Without the rapid stop function, shutdown of the AC grid in the event of faults is not
possible.
If no rapid stop function is installed, the inverter subunit cannot be separately isolated.
Block diagram
To implement the feature, a jumper in the AC cabinet must be removed and replaced with an
electrical connection to the external rapid stop switch.
The precise interconnection can be seen from the block diagram below.

8.3
Parameterizing the inverter
Adapt inverter to system requirements
Depending on the application, it is necessary to adapt the inverter to specific system
requirements by modifying parameters. You can find the available setting parameters in
Chapter Operator control and monitoring (Page 137).
The parameters of the inverter have pre-assigned values. These values must be checked
during commissioning and adapted if necessary.
Observe country-specific grid monitoring parameters
The system settings must be adapted to country-specific requirements regarding grid
monitoring parameters. The system settings can be appropriately set and modified via the
service pages in the menu. Only authorized service personnel have access to the service
pages via a password.
NOTICE
Withdrawal of operating permit and warranty
If you operate SINVERT PVS with incorrect grid monitoring parameters, the electrical utility
can withdraw your operating permit.
Only authorized service personnel are permitted to commission the inverter and adapt the
system settings to the country-specific grid monitoring parameters. Otherwise the warranty
will expire.
Commissioning is prohibited until the total system conforms to the national regulations and
safety rules of the application.
We assume no responsibility for incorrect grid monitoring parameters.

Decommissioning the inverter
8.4.1
Decommissioning an inverter subunit
With the SINVERT PVS, an inverter subunit can be decommissioned individually. This
means that if an error occurs in one inverter subunit, the other inverter subunits can remain
in operation.
Procedure
1. Turn the key-operated switch in the AC cabinet door of the inverter subunit to be switched
off to the position "1-Lock".
– The complete inverter shuts down and switches on again after 30 s in a controlled
fashion, apart from the inverter subunits on which the key-operated switch is in the "1Lock" position. These inverter subunits are now decommissioned.
2. Wait until the green indicator light (operation state indicator) in the control cabinet door of
the inverter subunit flashes slowly (operating state "IDLE").
WARNING
Hazardous voltages in the switched-off inverter subunit
The switched-off inverter subunit and the supply lines of the DC and AC inputs are still
live.
Results
● The green "READY" indicator light in the control cabinet door does not light up.
● The inverter subunit is locked but the supply lines are still live.
● The remainder of the inverter is still in operation.
WARNING
Hazardous voltages on the supply lines
The supply lines of the DC and AC inputs are live.
8.4.2
Decommissioning the entire inverter
In order to work on a SINVERT PVS inverter, the whole inverter unit must be isolated. This
means that all inverter subunits must be decommissioned.

8.4 Decommissioning the inverter
Procedure
1. Turn the key-operated switch in the AC cabinet door on all inverter subunits to the
position "1-Lock".
– After the first subunit is switched off, the complete inverter shuts down and attempts to
switch on again after 30 s in a controlled fashion, apart from the inverter subunits on
which the key-operated switch is already in the "1-Lock" position.
– Therefore, all inverter subunits should be switched off rapidly because the inverter will
try to switch on the remaining subunits again.
2. After all inverter subunits have shut down, wait until the green indicator light (operation
state indicator) in the control cabinet door of each inverter subunit flashes slowly
(operating state "IDLE").
3. Open the cabinet doors.
WARNING
Hazardous voltages in the inverter cabinet
The inverter is live.
4. Set the circuit breaker in the AC connection section to "0".
5. Switch off the auxiliary power supply.
6. Switch off the DC voltage (PV array).
7. Use a measuring device to check there is no voltage at the DC and AC inputs.
Results
● The green "READY" indicator light in the control cabinet door does not light up.
● The inverter is locked and the cabinet is isolated.
WARNING
Hazardous voltages on the supply lines
The supply lines of the DC and AC inputs are live.

9.6 Rapid stop function
9.6
Rapid stop function
The "rapid stop function" of the PVS inverter unit is used for fast shutdown of the AC grid in
the event of faults and emergencies (e.g.: component malfunctions, excessively high
temperatures, etc.).
Triggering the rapid stop function results in infeed mode abort.
WARNING
Hazardous voltages in the cabinet following actuation of rapid stop
The system is not isolated even after actuation of the rapid stop function. There are still
hazardous voltages present in the cabinets.
Procedure and further measures
1. In the case of faults, the rapid stop switch installed at the suitable position must be
actuated (see also Chapter Rapid stop function (Page 125)).
2. Shut down system (see Chapter Decommissioning the entire inverter (Page 134))
3. Eliminate the fault
4. Disengage rapid stop button
5. Execute commissioning (see Chapter Commissioning the inverter (Page 128))

Replacing the fan of the inverter module (ALM)
The typical service life of the device fans is 50,000 hours. In practice, however, the service
life depends on other variables (e.g., ambient temperature, cabinet enclosure, etc.) and,
therefore, may deviate from this value.
The fans must be replaced in good time to ensure that the device is available.
Requirements
● The control cabinet has been properly shut down. See Chapter Decommissioning the
entire inverter (Page 134).
● The feeders at the DC and AC inputs are de-energized.
● A voltage tester is available to check that the cabinet is de-energized.
● A cabinet key is available.
