5.1 Selecting the Mounting Location
Requirements for the mounting location:
☐ The ambient temperature is within the operating temperature range of ‒20°C to +50°C.
☐ The humidity is within the range of 5% to 95%.
☐ The altitude of the mounting location is below the maximum installation altitude of 4,000 m above sea level.
☐ The mounting location is in an industrial area.
☐ The mounting location must not block any escape routes.
☐The mounting location is clear and safely accessible at all times without the use of additional aids being necessary
(such as scaffolding or lifting platforms). Non-fulfillment of these criteria may restrict servicing.
☐ The mounting location is suitable for the weight and dimensions of the Communit.
☐ The mounting location is not exposed to direct solar irradiation.
☐ Mounting location is protected from rain as far as possible.
Overvoltage protection for installation altitudes above 2,000 m
For installation altitudes above 2,000 m, the overvoltage category is reduced to class II in accordance with
EN 50178.
• If necessary, install overvoltage protection modules. Thus, overvoltages of category III can be reduced to
overvoltages of category II.
Disconnection device
A disconnection device must be available for the installation work and commissioning in order to safely disconnect
the Communit from the voltage supply.
• Install a disconnection device close to the Communit. The disconnection device must be easily accessible.
Requirements for the bridging time in the event of voltage dips
The operators of PV systems are obliged to fulfill the requirements of the feed-in directives valid at the respective system
location.
The directives demand, depending on the system location, among other things the continued operation of the PV power
plant (including measures for grid stabilization) even in the event of short-term voltage dips.
In order to ensure this, the Communit is fitted as standard with a redundant electricity supply that ensures a bridging time
of 150 ms.
For further requirements, such as in unstable utility grids, SMA Solar Technology AG offers a redundant electricity supply
with an additional maintenance-free buffer module based on capacitors. A bridging time of at least six seconds is thus
ensured.
This support is not valid for the customer installation location.

Risk of injury due to inappropriate transport or mounting of the product
The product is heavy. If you try to move the product on your own, you run a risk of being injured. The maximum product
weight is 45 kg.
• Always have two persons transport and mount the product.
• Wear suitable personal protective equipment for all work on the device.
Procedure:
1. Excavate a pit. Ensure that the burial depth for the base is 660 mm. Tip: the optimum burial depth is marked on the
sides of the base.
2. Place the base in the excavated pit. The side with the kick plate must be at the front.
3. Attach the base extensions to the base:
• Place the first base extension on the base.
• Screw the first base extension into place at the four anchoring
points. Use the square washers with brackets.
• Place the second base extension on the first base extension.
• Screw the second base extension into place at the four
anchoring points. Use the square washers with brackets.
4. Lay all cables necessary for connecting the Communit. Observe all protective measures relating to the type of
cable-laying and the cable-laying specifications of the cable manufacturer.
Damage to the cables due to compaction of the ground
Heavy mechanical pressure during compaction of the ground can damage the cables.
• Protect the cables in the ground, for example by back-filling with sand or by using protective conduits.
5. Lead all necessary cables through the base and the base extensions. Take the length of the cables up to the
connection points into account (see Section6.1 "Overview of the Connection Area", page22).
6. Fill the pit with fine gravel up to the burial depth.
7. Compact the ground sufficiently.
8. Ensure that the base is firmly positioned.
9. Position the Communit on the base extension.

locking latches inwards.
12. Mount the upper kick plate under the Communit on the second
base extension and attach using two countersunk screws.
13. Ensure that all connectors inside the Communit are firmly positioned.
5.4 Determining the Optimum Mounting Location for the Antenna

&$87,21
Radiation hazard due to high power density of the antenna
Electromagnetic radiation from the antenna can be damaging to health.
• Maintain a personal safety clearance of at least 4 cm from the antenna in operation.
Procedure:
1. Connect the antenna cable plug to the router (see Section6.4 "Connecting the Cables to the Network Switch and
Router", page29).
2. Select the mounting location of the antenna. Take the maximum cable length of 5 m into account.
3. Check whether the signal strength at the selected mounting location is sufficient:
• Log into the router (see Section7.2 "Configuring the Router", page33).
• Read off the signal strength in the field Signal strength.
The signal strength is sufficient if the field Signal strength is showing either Good or Very good.
Installation Manual Communit-IA-A1-en-22 19
5 Mounting SMA Solar Technology AG
• Mount the antenna (see Section5.5 "Mounting the Antenna", page20).
The signal strength is insufficient if the field Signal strength is showing either Bad or Low.
• Select a different mounting location.
• Repeat step 3.
5.5 Mounting the Antenna
1. Mark the drill holes.
2. Drill holes with a diameter of 8 mm at the marked position.
3. Insert the screw anchors. Attach the bracket to the wall using the
screws.
4. Loosen the screw connection from the antenna.
5. Using the cable, guide the antenna sideways into the bracket.
6. Tighten the antenna cable gland (torque: 20 Nm). Hold on to the
antenna when doing this. This is in order to avoid twisting the cable.
7. Lay the cable to the router. If necessary, drill a hole in the station for feeding through the cable at a suitable place
and use either a protective conduit or cable channel.
