The environmental requirements for ES927 board are the same as for any other board mounted inside
Sinus Penta, Iris Blue and Penta Marine inverter lines.
Please refer to the user manuals of the products above for detailed specifications.
7.1.1. Environmental Requirements for Equipment Installation, Storage and
Transport
Any electronic board installed in the inverters manufactured by Elettronica Santerno is tropicalized. This
enhances electrical insulation between the tracks having different voltage ratings and ensures longer life
of the components. It is however recommended that the requirements below be met:
Maximum surrounding air temperature
–10°C to +55°C
It might be necessary to apply 2% derating of the rated current
for every degree beyond the stated temperatures depending on
the inverter model and the application category.
Ambient temperatures for storage and
transport
–25°C to + 70°C
Installation environment
Pollution degree 2 or better (according to IEC 61800-5-1).
Do not install in direct sunlight and in places exposed to
conductive dust, corrosive gases, vibrations, water sprinkling or
dripping (except for IP54 models); do not install in salty
environments.
Altitude
Max. altitude for installation 2000 m a.s.l. For installation above
2000 m and up to 4000 m, please contact Elettronica Santerno.
Above 1000 m, derate the rated current by 1% every 100 m.
Operating ambient humidity
From 5% to 95%, from 1g/m
3
to 29g/m
3
, non-condensing and
non-freezing (class 3k3 according to EN 50178).
Storage ambient humidity
From 5% to 95%, from 1g/m
3
to 29g/m
3
, non-condensing and
non-freezing (class 1k3 according to EN 50178).
Ambient humidity during transport
Max. 95%, up to 60g/m
3
; condensation may appear when the
equipment is not running (class 2k3 according to EN 50178).
Storage and operating atmospheric
pressure
From 86 to 106 kPa
(classes 3k3 and 1k4 according to EN 50178).
Atmospheric pressure during transport
From 70 to 106 kPa (class 2k3 according to EN 50178).
WARNING
As environmental conditions strongly affect the inverter life, do not install the
equipment in places that do not have the above-mentioned ambient
conditions.
WARNING
Always transport the equipment within its original package.
