2 Safety SMA Solar Technology AG
Operating manualEVCxx-10-BE-en-108
DANGER
Danger to life due to electric shock in case of overvoltages and if surge
protection is missing
Overvoltages (e.g. in the event of a flash of lightning) can be further conducted into the building
and to other connected devices in the same network via the network cables or other data cables
if there is no surge protection. Touching live parts and cables results in death or lethal injuries due
to electric shock.
• Ensure that all devices in the same network are integrated in the existing overvoltage
protection.
• When laying the network cable outdoors, ensure that there is suitable surge protection at
the network cable transition from the product outdoors to the network inside the building.
• The Ethernet interface of the product is classified as "TNV-1" and offers protection against
overvoltages of up to 1.5kV.
WARNING
Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be generated inside the product under fault
conditions. In this state, switching operations can cause a fire inside the product or explosion.
Death or lethal injuries due to hot or flying debris can result.
• In the event of a fault, do not perform any direct actions on the product.
• Ensure that unauthorized persons have no access to the product.
• Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped,
and secure it against reconnection.
• Only perform work on the product (e.g., troubleshooting, repair work) when wearing
personal protective equipment for handling of hazardous substances (e.g., safety gloves,
eye and face protection, respiratory protection).
WARNING
Risk of injury due to toxic substances, gases and dusts.
In rare cases, damages to electronic components can result in the formation of toxic substances,
gases or dusts inside the product. Touching toxic substances and inhaling toxic gases and dusts
can cause skin irritation, burns or poisoning, trouble breathing and nausea.
• Only perform work on the product (e.g., troubleshooting, repair work) when wearing
personal protective equipment for handling of hazardous substances (e.g., safety gloves,
eye and face protection, respiratory protection).
• Ensure that unauthorized persons have no access to the product.

5.1 Requirements for Mounting
Requirements for mounting location:
WARNING
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires. This can result in death or serious
injury.
• Do not mount the product in areas containing highly flammable materials or gases.
• Do not mount the product in potentially explosive atmospheres.
☐ Installation may only be carried out in places with restricted access (e.g. private property,
company premises). Use of the product as a public charging station is not permitted.
☐ Do not mount the inverter on a pillar.
☐ A solid, flat support surface,e.g. concrete or masonry, must be available for mounting. The
difference between the outer anchoring points must not exceed 5mm.
☐ The support surface for installation must be made of a non-flammable material.
☐ Installation must be carried out so that the plug of the charging cable is always at a height of
0.5 m to 1.5 m above floor level.
☐ The mounting location must be suitable for the weight and dimensions of the product (see
Section14, page59).
☐ The mounting location must not be exposed to direct solar irradiation. If the product is
exposed to direct solar irradiation, the exterior plastic parts might age prematurely and
overheating might occur. When becoming too hot, the product reduces its power output to
avoid overheating.
☐ Mounting location must be selected so that the EV Charger and the vehicle can be connected
with the charging cable. The charging cable must not be strained, squeezed or bent.
☐ No other device may be installed under the product.
☐ The mounting location should be freely and safely accessible at all times without the need for
any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing.
☐ All ambient conditions must be met (see Section14, page59).
Permitted and prohibited mounting positions:
☐ The product may only be mounted in a permitted position. This will ensure that no moisture can
penetrate the product.
☐ The product should be mounted such that the LED signals can be read off without difficulty.
