2.2 Safety Instructions
Electrical Risk
Risk of electric shock when touching conductive parts
High voltages that can cause electrical shocks are present in the inverter. Work on the inverter is only
allowed if the power is disconnected and in compliance with the guidelines that apply at the
installation location.
• Disconnect the following components:
– Grid voltage for grid feeding
– Internal supply
–DC voltage from the PV array
– Additional external voltages (e.g., control signals of a control room)
• Ensure that the device cannot be reconnected.
•Ensure that no voltage is present.
• Ground and short-circuit.
• Cover or safeguard any adjacent live components.
Electric shock through capacitors not fully discharged
Hazardous voltages may still be present in the inverter even if the AC and DC main switches are
switched off.
• Wait at least 12 minutes after switching off the inverter.
Electric shock caused by damage on the inverter
The operation of a damaged inverter can lead to serious or lethal injuries through electric shock.
• Operate the inverter only in technically proper and operationally safe status.
• Check the inverter regularly for visible damage.
• Ensure that all safety features are freely accessible at all times.
• Regularly check for correct functioning.
Electric shock caused by ground fault
In case of a ground fault, assume that grounded plant components are still live.
• Ensure that no voltage is present before touching.
Electric shock when entering the PV field
The insulation monitoring device with GFDI or Remote GFDI does not provide protection from injury
when GFDI is activated. PV modules grounded by means of GFDI disperse voltage to ground.
When entering the PV field, lethal electric shocks may occur.
• Before entering the PV field, switch the PV modules to insulated operation.
• Ensure that the insulation resistance of the PV field is greater than 1 k Ω .

3.1.6 Quick-Stop
In case of emergency, this switch enables disconnection of the inverter from the PV array and the
medium-voltage grid within 500 ms.
Tripping the quick-stop function
The quick-stop function may only be tripped if there is imminent danger.
Pressing the quick-stop button does not trip rapid discharge of the capacitor.
Pressing the quick-stop button opens the DC contactor, switches off the inverter bridge and
disconnects the inverter from the AC grid.
3.1.7 Key Switch
The key switch is used to switch the Sunny Central on and off.
Switch position "Start"
After turning the switch to the "Start" position, the Sunny Central switches from "Stop" mode to
"Grid monitoring" mode. If there is sufficient irradiation and a valid grid connection, the Sunny Central
switches to feed-in operation. If there is insufficient irradiation, the input voltage is too low for startup,
and the Sunny Central remains in the "Grid monitoring" state.
Switch position "Stop"
If the key switch is turned to "Stop" when the Sunny Central is in the "Grid monitoring" mode, a motor
drive automatically shuts off the DC main switch. The Sunny Central goes into the "Stop" mode.
If the key switch is turned to "Stop" when the Sunny Central is in "MPP load operation", the
Sunny Central switches to the operating state "Shutdown". Once shutdown is complete, the AC
contactor and the DC main switch tur n off aut oma tic all y and the Sunny C entral goe s into "Sto p" mode.

• Monitoring network: takes care of the monitoring, parameterization and remote diagnosis
functions.
• Regulation network: here, the specifications issued by the distribution grid operator for grid
stability management are transmitted. Since the regulation network is used exclusively for
transmitting the data of the distribution grid operator, the specifications are made available in
the requisite time.
If there is only a low level of data flow in the monitoring network, the grid operator specifications can
also be transmitted via the monitoring network. In this case, there is no need for 2 networks.
The operator can access all data stored in the SC-COM via an Ethernet connection.
You can set the parameters of the inverter via the SC-COM.
The networks are realized on the basis of copper cables or optical fibers.
PV Plant Communication Type
The interface of the SC-COM is set by default to "COM 3". The default setting of the baud rate
for the following options is:
• Option 11/0 without hub: baud rate 115 200
• Options 11/1 and 11/2 with hub: baud rate 19 200
Do not modify these settings.

10.4.5 Connecting the External Target Value Specification
Signal Transmission
External target values for reactive and active power are normally specified by the distribution
grid operator, and e.g. distributed via a radio ripple control receiver. The Power Reducer Box
receives the target values from the radio ripple control receiver and sends these to the inverter
via the SC-COM. The inverter then implements the distribution grid operator specification and
feeds, for example, a specified reactive power into the power distribution grid. Ask your
distribution grid operator which signal transmission is used.
If these target values are not transmitted via the SC-COM and Power Reducer Box, there are
terminals located in the inverter for connecting the external target value specifications.
The inverter processes standard signals from 4 mA ... 20 mA.
How the external target value specification works
You will find further information on how the external target value specification works in the
inverter's operating manual.
1. Lead the external target value specification cable into the connection cabinet (see section
10.3).
2. Connect the cable according to the circuit diagram (see section 10.4.1).
3. Remove the shield clamp from the busbar.

Quick-stop function for several Sunny Centrals in one plant
Damage to the Sunny Central due to missing quick-stop function.
• In plants with more than one inverter, the quick-stop circuits of the installed devices must be
linked with each other and tested for correct functioning.
• The quick-stop string may only be supplied with voltage from one Sunny Central.
If several Sunny Centrals are in operation in one plant, they must all be switched off when the
quick-stop button is pressed on one inverter (creation of a quick-stop stop string). To achieve this, the
quick-stop buttons of all Sunny Centrals are switched in series.
The necessary 24 V supply voltage for the quick-stop string can be tapped internally by up to two
Sunny Centrals installed in one station. If more than two Sunny Centrals are installed in one station or
th e di sta nce bet wee n th e tw o Su nny Cen tra ls i s gr eat er t han 5 m, the voltage supply must be provided
