6.1 Choosing a Mounting Location
Requirements for the mounting location:
☐ A firm, even foundation, e.g., a concrete surface, must be available for mounting.
☐ The mounting location must be suitable for the weight and dimensions of the Multicluster Box
(see Section 12 "Technical Data", page 41).
☐ The mounting location must be clear and safely accessible at all times without any need for
auxiliary equipment.
☐ The mounting location must not hinder access to disconnection devices.
☐ All local requirements concerning minimum passage widths and escape routes must be
observed.
☐ Climatic conditions must be met (see Section 12 "Technical Data", page 41).
☐ The mounting location must be below 2,000 m above MSL. For altitudes over 2,000 m above
MSL, contact the SMA Service Line.
Danger to life due to fire or explosion
Despite careful construction, electronic devices can cause fires if they are not installed properly.
This may result in death or serious injury.
• Do not install the Multicluster Box on flammable construction materials.
• Do not store any highly flammable materials or products in the vicinity of the Multicluster Box.
• Do not install the Multicluster Box in potentially explosive areas.
Optimum mounting location
The ambient temperature of the Multicluster Box influences the tripping threshold of the
circuit breakers for the Sunny Island inverters. The higher the temperature, the earlier the
circuit breakers will trip. At high ambient temperatures, the derating function of the
Sunny Island inverters inhibits premature tripping of the circuit breakers.
• To ensure optimum operation, mount and install the Multicluster Box and the
Sunny Island inverters at the same location.
