3.1 Pre-Installation

3.1.1 Planning the Installation Site

NOTICE
Plan the installation site of the frequency converter
before commencing the installation. Neglecting this may
result in extra work during and after installation.
Select the best possible operation site by considering
the following (see details on the following pages and
the respective Design Guides):
•
Ambient operating temperature
•
Installation method
•
How to cool the unit
•
Position of the frequency converter
•
Cable routing
•
Ensure that the power source supplies the correct
voltage and necessary current.
•
Ensure that the motor current rating is within the
maximum current from the frequency converter.
•
If the frequency converter is without built-in
fuses, ensure that the external fuses are rated
correctly.
Voltage [V] Altitude restrictions
380-690 At altitudes above 2000 m, contact Danfoss

3.1.2 General Considerations

Wire access
Ensure that proper cable access is present including
necessary bending allowance. As the IP00/IP20 enclosure is
open to the bottom, cables must be fixed to the back
panel of the enclosure where the frequency converter is
mounted, i.e. by using cable clamps.
CAUTION
All cable lugs/shoes must mount within the width of the
terminal bus bar.
Space
Ensure proper space above and below the frequency
converter to allow airflow and cable access. In addition
space in front of the unit must be considered to enable
opening of the panel door, see Illustration 3.1 to
Illustration 3.3.
