SMA SB 240 - Manual (Page 26)

☐ The mounting location must be suitable for the installation of the Sunny Multigate in a
distribution box.
☐ The mounting location must be suitable for the weight and dimensions of the Sunny Multigate
(see Section 14 "Technical Data", page 66).
☐ The mounting location must be inaccessible to children.
☐ AC cable route of the entire PV system with Sunny Multigate: maximum 30 m
When installing several Sunny Multigate devices in a PV system, you must lay the AC cable of
each Sunny Multigate to the respective inverter separately in order to guarantee trouble-free
communication between the Sunny Multigate and the inverter.

Sunny Multigate).
☐ A robust support surface must be available for mounting the device, e.g. concrete, walls. In
living areas, ensure that the support surface is not drywall or similar.
☐ 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.
☐ The mounting location should not be exposed to direct solar irradiation.
☐ Climatic conditions must be met (see Section 14 "Technical Data", page 66).
☐ The ambient temperature must be between -40°C and 25°C. This will ensure optimal
operation of the Sunny Multigate.
Clearances:
☐ The clearance inside a metal distribution box must be at least 12.7 mm to walls or other
components.
☐ Within an industrial closure, observe the following clearances to ensure sufficient ventilation:
