2.3.1. ENVIRONMENTAL REQUIREMENTS FOR THE EQUIPMENT
INSTALLATION, STORAGE AND TRANSPORT
Any electronic board installed in the inverters manufactured by Elettronica Santerno is tropicalised. This enhances electrical
insulation between the tracks having different voltage ratings and ensures longer life of the components. It is however
recommended that the prescriptions below be strictly followed:
Maximum surrounding air temperature
–10 to 40 °C with no derating
from 40°C to 50°C with no derating or with 2% derating of the rated
current for every degree beyond 40°C
based on the inverter model and
the application category (see
OPERATING TEMPERATURES BASED ON
APPLICATION CLASSES in the Installation Instructions manual).
Ambient temperatures for storage and
transport
–25°C to 70°C
Installation environment
Pollution degree 2 or better.
Do not install in direct sunlight and in places exposed to conductive dust,
corrosive gases, vib
rations, water sprinkling or dripping (except for IP54
models); do not install in salty environments.
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 EN50178)
From 5% to 95%, from 1g/m
3
to 29g/m
3
, non condensing and non
freezing (class 1k3 according to EN50178)
Ambient humidity during transport
Max. 95%, up to 60g/m
3
; condensation may appear when the equipment
is not running (class 2k3 according to EN50178)
Storage and operating atmospheric pressure
From 86 to 106 kPa
(classes 3k3 and 1k4 according to EN50178)
Atmospheric pressure during transport
From 70 to 106 kPa (class 2k3 according to EN50178).
As ambient conditions strongly affect the drive
life, do not install the equipment in
places that do not have the above-mentioned ambient conditions.
Always transport the equipment within its original package.
