5.1 Selecting the Mounting Location
Requirements for the mounting location:
☐ If the top-hat rail power supply is used, the mounting location must be in the vicinity of a
socket-outlet in the interior area.
☐ The mounting location must be protected against dust, moisture and corrosive substances.
Observe the maximum cable length:
☐ If a Power Module is used, observe the maximum cable length of 10 m for the voltage supply
cable.
Observe minimum clearances:
Figure8: Minimum clearances to be observed
• Observe the minimum clearance to walls and other devices or objects.
• Observe the minimum clearance of 1 m to devices using the 2.4 GHz frequency band, e. g.
WLAN devices or microwave ovens. This is to prevent any reduction in connection quality or
data transmission speed.

16 BTREPOUT-IA-en-11 Installation Manual
Determining the Mounting Location
Determine the mounting location by varying the distance between the Bluetooth Repeater Outdoor
and devices with a critical connection signal until all devices display at least a "good" signal.
Requirements:
☐The rotary switch MODE is at position 0 (see Section7.1 "Setting the MODE", page23).
☐The rotary switch NetID is set to the NetID of the plant (see Section7.2 "Setting the NetID",
page23).
1. Decommission the plant (see the manual of the inverter and of the communication product).
Thus, you ensure that the Bluetooth Repeater Outdoor is integrated into the SMA Bluetooth
network at the point where the dead zone is, thus improving the Bluetooth connection at that
point.
2. Position the Bluetooth Repeater Outdoor half way between the devices with critical connection
quality.
3. Connect the voltage supply (see Section6 "Electrical Connection", page19).
4. Recommission the plant (see the installation manual of the inverter and of the communication
product).
5. Repeat the plant search with the communication device (see the communication product
manual, e.g. Sunny Beam with Bluetooth, Sunny Explorer).
Danger to life due to electric shock when opening the inverter
Lethal voltages are present in the conductive parts of the inverter.
• Prior to performing any work on the inverter, disconnect the inverter from any voltage sources
on the AC and DC sides (see inverter installation manual). Observe the waiting time to allow
the capacitors to discharge.

Installation Manual BTREPOUT-IA-en-11 17
6. Check that the connection quality for all devices is at least "good". During this procedure, all
devices must be in their usual positions (e.g., the Sunny Beam with Bluetooth must not be held
directly in front of the Bluetooth Repeater Outdoor):
☑ The connection quality displayed is at least "good" for all devices. Mount the Bluetooth
Repeater Outdoor there at this location.
✖ The connection quality displayed is not at least "good" for all devices?
•Move the Bluetooth Repeater Outdoor to another position and check the connection
signals again.
• If necessary, install additional SMA Bluetooth Repeater Outdoor devices.

6 Electrical Connection
6.1 Connecting the Bluetooth Repeater Outdoor with Top-Hat Rail
Power Supply Unit to the Voltage Supply
Requirements for the connection cable:
☐ Number of insulated wires: 2
☐ Cable cross-section: 1 mm2 … 2.5 mm2
☐ External diameter: 5 mm … 10 mm
☐ Cable must be suitable for outdoor installations.
☐ Cable must be UV resistant.
☐ If a grid connection plug is used in outdoor installations: Grid connection plug must be suitable
for outdoor installations.
Danger to life due to electric shock in the event of missing separators and missing fuses
on the AC cable
• The AC cable used for the connection must have a separator.
– In the case of an alternating current supply by means of an IT system the separator must
have two poles in accordance with IEC 60364-1.
• The separator must be easily accessible.
• If the separator is a plug-connection, the socket-outlet must be situated in close proximity to the
Bluetooth Repeater Outdoor.
• The AC cable used for the connection must be equipped with a fuse (16 A for Europe and
20 A for the US and Canada).
Danger to life due to electric shock in the event of mixing up the Bluetooth Repeater
Outdoor
Only the Bluetooth Repeater Outdoor of the device type „BTREP-OUT.GR1“ is allowed to be
connected via the top-hat rail power supply unit to the alternating current grid.
•Ensure that the Bluetooth Repeater Outdoor is of device type „BTREP-OUT.GR1“ before
connecting it to the alternating current grid. To do so, check the type label on the
Bluetooth Repeater Outdoor (see Section3.3 "Identifying the SMA Bluetooth Repeater
Outdoor", page10).

1. Loosen the screws of the enclosure lid and remove the lid.
2. Unscrew the nut from the lower left corner of the cable gland and push out the filler-plug.
3. Preparing the cable:
– Remove 40 mm of the cable sheath from the
side of the Bluetooth Repeater Outdoor.
– Shorten unused insulated wires flush with the
cable sheath.
– Strip approx. 10 mm off the wires.
4. Insert the cable into the enclosure through the nut
and the cable gland.
5. Connecting the cable to the feed-through terminal
in the enclosure:
– Push the terminal 1 and terminal 2 of the
feed-through terminal open using a screwdriver
(2.5 mm).
– Connect the conductor to terminal 1 and the
insulator to terminal 2.
6. Separate the AC grid connection point from the alternating current grid using the separator.
Thus you ensure that there is no voltage present at the AC grid connection point.
7. Connect the Bluetooth Repeater Outdoor to the voltage supply.
• Plug the grid connection plug into the socket-outlet, if a grid connection plug is used.
• If no grid connection plug is used, connect the other end of the cable to the voltage supply
as desired, e.g. via a cable junction box.
8. Connect the AC grid connection point to the AC grid using the separator.
☑LED DC OK of the top-hat rail power supply unit and LED RDY of the Bluetooth Repeater
Outdoor are glowing green
✖LED DC LO of the top-hat rail power supply unit or LED RDY are not in operation or are
glowing yellow?
• Rectify the fault (see Section10.1 "Voltage Supply", page27).
