3.3.1 Increased cooling
Cooling air circulation on the DS7 soft starter can be improved by using an
optional DS7-FAN-… device fan
This makes the following possible:
•
Operation at higher ambient air temperatures
•
A compact setup and directly combining the unit with other components
•
A higher number of starts per hour
The choice of device fan is based on the rated operational current (yyy) for
the corresponding size.
Table 11: Device fans for the various rated operational currents
→
The supplied cooling air must have a temperature between
-5 and +40 °C. A derating is required for higher temperatures
(up to +60 .maximum):
•
2 percent of the rated operational current I
e
per Kelvin (K)
temperature rise from +40 °C
•
1 percent of rated operational current I
e
per kelvin (K) of
temperature rise after +40 °C with device fan (DS7-FAN-…)
→
DS7-FAN-… device fans are temperature-controlled, always run
during ramp times (t-Start, t-Stop), and will continue running
until the heat sink cools down again. The fan is then
automatically switched off.
→
It is advisable to install device fan DS7-FAN-… before installing
soft starter DS7 in the basic device.
This helps prevent additional steps for removal and changes in
the installation.
DANGER
The device fan must only be mounted in a de-energized state.
