2.2 Safety Information
This section contains safety information that must be observed at all times when working on or with
the product.
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 high voltages of the PV array
When exposed to light, the PV array generates dangerous DC voltage, which is present in the
DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage
sources on the AC and DC sides as described in the inverter manual. When doing so, note
that even if the DC load-break is switched off, there will be dangerous direct voltage present
in the DC conductors of the inverter.
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 seals on the enclosure lids in subfreezing conditions
If you open the enclosure lids when temperatures are below freezing, the enclosure seals can be
damaged. Moisture can penetrate the product then.
• Only open the enclosure lid if the ambient temperature is not below 0°C (32°F).
• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lids (e.g. by melting the ice with warm air).
Observe the applicable safety regulations.
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.
NOTICE
Damage to the inverter due to moisture ingress during electrical installation
• Never open the inverter when it is raining or snowing, or the humidity is over 95%.
• For attaching the conduits to the enclosure, only use UL-listed rain-tight conduit fittings for
wet locations.
• Seal all unused openings tightly.
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 2.03.01.R may take approx. 30minutes. 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 2.03.01.R.

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: 3.5mm (0.14in)) 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 with
a Torx screwdriver (TX 25) and remove the equipment grounding conductor from the
inverter; screw each screw back in with a Torx screwdriver (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
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.

6 Commissioning the Rooftop Communication Kit SMA Solar Technology America LLC
Installation manualRoofCommKit-P2-US-IA-xx-1020
6 Commissioning the Rooftop Communication Kit
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 < 30V within 30
seconds and the display and LEDs have gone out after 90 seconds. If the voltage is >
30V 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 SunnyPortal and detect the TS4-R components in SunnyPortal
(www.SunnyPortal.com).
