OUNTING
• Install vertically;
•
Make sure to allow a min. clearance of 5 cm on both sides and 10 cm on top and bottom;
•
use cable-glands to maintain degree of protection IP20.
ENVIRONMENTAL REQUIREMENTS FOR THE BRAKING UNIT INSTALLATION, STORAGE AND TRANSPORT
Operating ambient temperatures 0-40°C with no derating
from 40°C to 50°C with a 2% derating of the rated current for
each degree beyond 40°C
Ambient temperatures for storage and
transport - 25°C - +70°C
Installation environment Pollution degree 2 or higher.
Do not install in direct sunlight and in places exposed to
conductive dust, corrosive gases, vibrations, water sprinkling
or dripping; do not install in salty environments.
Altitude Up to 1000 m above sea level.
For higher altitudes, derate the output current of 1% every
100m above 1000m (max. 4000m).
Operating ambient humidity From 5% to 95%, from 1g/m 3 to 25g/m 3 , non condensing
and non freezing (class 3k3 according to EN50178)
Storage ambient humidity From 5% to 95%, from 1g/m 3 to 25g/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)
CAUTION
Ambient conditions strongly affect the inverter life. Do not install the equipment in
places that do not have the above-mentioned ambient conditions.
COOLING SYSTEM AND DISSIPATED POWER
The braking unit is provided with a heatsink reaching a max. temperature of 80 °C.
Make sure that the bearing surface for the braking unit is capable of withstanding high temperatures. Max.
dissipated power is approx. 150 W and depends on the braking cycle required for the operating conditions of
the load connected to the motor.
The max. temperature alarm for the braking unit shall be used as a digital signal to control the inverter stop.
