Risk Of Fire - SMA Sunny Tripower CORE1-US Instructions D'installation

2 Safety
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 inverter is classified as "TNV-1" and offers protection against
overvoltages of up to 1.5 kV.
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 or explosion. Death or lethal
injuries due to fire or flying debris can result.
• In case of error, only carry out corrective measures specified by SMA Solar Technology AG
(for corrective measures see section "troubleshooting" in the detailed manual. If no
corrective measures are specified, do not perform any actions on the product. Contact the
Service.
• Ensure that unauthorized persons have no access to the product.
• Disconnect the AC circuit breaker and secure it against reconnection. Do not operate the
AC load-break switch on the product.
• Disconnect the PV array from the product via an external disconnection device. Do not
operate the DC load-break switch on the product in the event of ground fault
Risk of burns due to hot enclosure parts
The enclosure and the enclosure lid may get hot during operation. The DC load-break switch can
not become hot.
• Do not touch hot surfaces.
• Wait until the inverter has cooled down before touching the enclosure or enclosure lid.

Risk of fire

• To reduce the risk of fire, connect only to a circuit provided with maximum branch-circuit
overcurrent protection 100 A in accordance with the National Electrical Code
NFPA 70 or the Canadian Electrical Code
