2.2 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working on or with
the product.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
DANGER
Danger to life due to electric shock when live components or cables of the
inverter are touched
High voltages are present in the conductive components or cables of the inverter. Touching live
parts and cables of the inverter results in death or lethal injuries due to electric shock.
• Disconnect the inverter from voltage sources and make sure it cannot be reconnected
before working on the device.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch non-insulated parts or cables.
CAUTION
Increased electromagnetic radiation through the antenna
During operation, the antenna produces an electromagnetic field and can interfere with other
devices (e.g., pacemakers) due to electromagnetic interference.
• Persons must not remain closer than 20 cm (8 in) to the antenna for long periods of time.

NOTICE
Damage to the enclosure seal in subfreezing conditions
If you open the inverter when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the inverter if the ambient temperature is not below 0°C (32°F).
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the inverter (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.
NOTICE
Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Close tightly all enclosure openings.
• Only use listed rain-tight or liquid-tight conduit fittings to attach the conduits to the product.
NOTICE
Damage to communication assembly in the inverter due to an interruption in
the voltage supply during the firmware update
The firmware update to a version higher than 2.03.61.R may take approx. 30minutes. The
inverter must be continually supplied with voltage for the entire course of the firmware update.
• Ensure that the inverter is supplied with voltage during the firmware update to a version
higher than 2.03.61.R.
NOTICE
Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product
through electrostatic discharge.
• Ground yourself before touching any component.

After installation of the Rooftop Communication Kit, the secure power
supply operation is no longer supported.
The Rooftop Communication Kit supports the Rapid Shutdown function. A rapid shutdown is
triggered in the event of a grid failure or an interruption of the AC supply of the inverter. Thus
the supply of the outlet for secure power supply operation is no longer possible.
• If a switch and an outlet for secure power supply operation are connected to the inverter,
the connections for the secure power supply operation have to be removed from the
inverter before installation of the Rooftop Communication Kit:
– Disconnect the inverter from all voltage sources (see inverter manual).
– Remove the conductors of the outlet for secure power supply operation from the
terminal block SPS. To release the conductors from the terminals, open the terminals
with a flat-blade screwdriver (blade width: 3.5°mm (0.14°in)).
– Screw out the screws from the SPS terminal block using a flat-blade screwdriver
(blade width: 3.5mm (0.14in)) and pull the terminal block out of the slot.
– Remove the equipment grounding conductor of the outlet for secure power supply
operation from the equipment grounding terminal. To do this, remove the screw (TX
25) and remove the equipment grounding conductor from the inverter; screw each
screw back in (TX 25).
– For secure power supply operation, remove the plug with the switch conductors from
the SPS slot of the communication assembly.
– Pull all conductors for secure power supply operation out of the inverter and uninstall
the switch and outlet of secure power supply operation.
Electrical installations (only applies to North America)
All electrical installations must be carried out in accordance with the local standards and the
National Electrical Code® ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.
• Before connecting the inverter to the utility grid, contact your local grid operator. The
electrical connection of the inverter must be carried out by qualified persons only.
• Ensure that no cables used for electrical connection are damaged.

• Guide the three guide pins on the
communication assembly through the holes in
the module.
• Carefully push the module down on the upper
edge and on the connection sockets until it
audibly snaps into both side locking tabs of the
communication assembly. The plug on the back
of the module is automatically pushed into the
socket terminal strip of the communication
assembly.

Cable requirements for the communication cable between Gateway and inverter:
☐ Number of conductors: 4
☐ Conductor cross-section: at least 0.22mm² (24AWG)
☐ Maximum external diameter: 8mm (0.31in)
☐ Maximum cable length: 305m (1000ft)
☐ The conductors should be twisted pairs if the total length of the communication cable exceeds
61m (200ft).
☐ The conductors should be shielded if the cable is laid in a nonmetallic cable raceway.
☐ UV-resistant for outdoor use
☐ The conductors lengths in the inverter must be as short as possible. This prevents contact with
live conductors.
☐ If the conductor is to be installed without conduit, the conductor has to be suited for outdoor
use.
☐ If the conductor is to be installed in a conduit together with live conductors, the conductor has
to be insulated for 600V.

Procedure:
1. If the conductor is installed in a separate conduit, mount the conduit to the enclosure opening:
• Remove the sealing plugs from the network connection opening on the inverter.
• Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
• Attach the conduit to the conduit fitting.
2. Guide the conductors from the conduit into the inverter. In the process, install the conductors in
the inverter such that they do not come into contact with AC conductor.
3. Strip off the conductor insulation by 7mm (0.28in).
4. In the case of fine stranded wire, provide the conductors with a bootlace ferrule.
5.
The terminal block with resistor must be inserted for proper operation.
If the terminal block with resistor is not inserted, the system will not function properly.
• Plug the 4-pole terminal block with
inserted resistor into the jack RSI/SPS on
the module.

6 Commissioning the Rooftop Communication Kit
Limited view of the data in SunnyPortal due to incorrect router
configuration
Due to an incorrect router configuration, the view of system data in SunnyPortal or in
SunnyPlaces is only possible to a limited extent. For unlimited access to system data in
SunnyPortal or in SunnyPlaces, the router must be configured as described in the following.
• Carrying out router configuration for outgoing connections: Permit access to UDP port
1024-65000 and TCP port 443.
Procedure:
1. Commission the inverter (see inverter manual).
2. Activate the user interface of the inverter (see the inverter manual).
3. Start the installation assistant (see the inverter manual).
4. Select the step Configuration of module technology and fill out the individual tabs. In the
last step Status, check the correct configuration.
5. Checking the Rapid Shutdown function of the TS4-R components:
• Ensure that the inverter feeds into the utility grid.
• Turn off the AC circuit breaker. As a result, the Rapid Shutdown function is tripped.
• Measure voltage on the DC inputs of the inverter or watch the display or the LEDs. The
Rapid Shutdown function works properly when the voltage drops to < 30V within 30
seconds and the display and LEDs have gone out after 90 seconds. If the voltage is >
30V and the display and LEDs have not gone out after 90 seconds, the Rapid Shutdown
function is not working properly and the system should not be put into operation. In this
case, check the installation.
6. Register the system in SunnyPortal and detect the TS4-R components in SunnyPortal
(www.SunnyPortal.com).
