Safety

Intended Use
The SMA EV Charger is an AC charging station that is designed for unidirectional charging of a vehicle. The SMA EV Charger along with the Sunny Home Manager 2.0 makes an intelligent charging station. If the SMA EV Charger is operated without Sunny Home Manager 2.0, the modes for intelligent charging are not available.
The product must only be used as stationary equipment.
The product is suitable for indoor and outdoor use.
The EVC7.4-1AC-10 must not be used in industrial environments.
The product must be tested in fast charging mode according to IEC 61851 before its first charging operation using a suitable measuring device for charging stations.
All components must remain within their permitted operating ranges and their installation requirements at all times.
The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the grid operator.

IMPORTANT SAFETY INSTRUCTIONS
Keep the manual for future reference.
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As with all electrical or electronical devices, there are residual risks despite careful construction. 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 electric shock when live components or cables are touched. High voltages are present in the conductive components or cables of the product. Touching live parts and cables results in death or lethal injuries due to electric shock.

Do not touch non-insulated parts or cables.
Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
Wear suitable personal protective equipment for all work on the product.

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 and 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.

CAUTION
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation. Touching hot enclosure parts can result in burn injuries.

Sand, dust and moisture penetration can damage the product and impair its functionality.

Only open the product if the humidity is within the thresholds and the environment is free of sand and dust.
Do not open the product during a dust storm or precipitation.

NOTICE
High costs due to inappropriate Internet tariff
Depending on use, the data volume of the product transferred via the Internet may vary in size. The data volume depends, for example, on the number of devices in the system, the frequency of device updates, the frequency of data transfer to Sunny Portal or the use of FTP push. High costs for the Internet connection can be the result.

SMA Solar Technology AG recommends using an Internet flat rate.
