12 V01Installation and Operating Instructions
5. The ambient temperature should be below 40°C to ensure optimal operation.
6. In order to avoid power reduction caused by overheating, do not mount the
inverter in a location that allows long-term exposure to direct sunlight.
7. The mounting method, location and surface must be suitable for the inverter's
weight and dimensions.
8. If mounted in a residential area, we recommend mounting the inverter on a
solid surface. Plasterboard and similar materials are not recommended due to
audible vibrations when in use.
9. Do not put any objects on the inverter.
10. Do not cover the inverter.

Installation and Operating Instructions V01 13
• Do not mount the inverter on flammable construction materials.
• Do not mount the inverter in areas where flammable materials are stored.
• Do not mount the inverter in areas where there is a risk of explosion.
4.2 Selecting the mounting location
1. Mount the inverter vertically or tilted backward by a maximum of 15°.
2. Never mount the inverter tilted forward or sideways.
3. Never mount the inverter horizontally.
4. Mount the inverter at eye level to make it easy to operate and to read the
display.
5. The electrical connection area must point downwards.
Warning!
Danger to life due to fire or explosion!

14 V01Installation and Operating Instructions
CAUTION!
Risk of injury due to the heavy weight of the inverter!
• When mounting, take into account that the inverter-weighs approx. 14 kg .
CAUTION!
Risk of injury if the inverter falls down!
• Before inserting screw anchors, measure the depth and distance of the holes.
• If the measured values do not fulfill the mounting requirement, redrill the
holes.
4.3 Mounting the inverter with the wall mounting bracket
Mounting procedures:
1. Use the wall bracket as a drilling template and
mark the positions of the drill holes, then drill
4 holes (φ10) to a depth of 55 to 60mm.
During operation, keep the drill vertical to the
wall, and hold the drill steady to avoid tilted
holes. After cleaning the dust from the holes,
measure their net depth.
2. After drilling holes in the wall, place four screw anchors into the holes, then
attach the wall mounting bracket to the wall using the self-tapping screws and
washers delivered with the inverter.

Installation and Operating Instructions V01 15
3. Hold the inverter using the handles on the sides and attach it tilted slightly
downwards to the wall bracket
4. Check both sides of the inverter to ensure that it is securely in place.
5. Push in the inverter as far as possible and attach it to both sides of the wall
bracket using the M5 screws and washers.
If a second protective conductor is required in your country, ground the inverter and
secure it so that it cannot be lifted off the wall bracket (see section 5.4.3 “ Second
protective grounding connection ”).

16 V01Installation and Operating Instructions
CAUTION!
Risk of injury due to electric shock!
• The external protective grounding conductor is connected to the
inverter’s protective grounding terminal through an AC connector, make
sure the connection is safe.
•When connecting, connect the AC connector first to ensure the inverter
grounding and then connect the DC inputs.
• When disconnecting, disconnect the DC inputs first and then disconnect
the AC connector.
• Do not, under any circumstances, connect the DC inputs when the AC
connector is unplugged.
WARNING!
Risk of injury due to electric shock!
• The inverter must be installed only by trained and authorized electricians.
• All electrical installations must be done in accordance with the National Wiring
Rules standards and all locally applicable standards and directives.
5 Electrical Connection
5.1 Safety

Installation and Operating Instructions V01 17
5.2 System layout of units without integrated DC switch
Local standards or codes may require that PV systems are fitted with an external
DC switch on the DC side. The DC switch must be able to safely disconnect the
open-circuit voltage of the PV array plus a safety reserve of 20%.
Install a DC switch to each PV string to isolate the DC side of the inverter. We
recommend the following electrical connection:
