Before performing the installation it is important to plan
the installation of the frequency converter. 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 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

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
At altitudes above 3 km, contact Danfoss regarding

Before unpacking the frequency converter, ensure
the packaging is intact. If any damage has
occurred, immediately contact the shipping
company to claim the damage.
Before unpacking the frequency converter, locate
it as close as possible to the final installation site
Compare the model number on the nameplate to
what was ordered to verify the proper equipment
Ensure each of the following are rated for the
same voltage:
•
Mains (power)
•
Frequency converter
•
Motor
Ensure that frequency converter output current
rating is equal to or greater than motor full load
current for peak motor performance
•
Motor size and frequency converter
power must match for proper overload
protection
•
If frequency converter rating is less than
motor, full motor output cannot be
achieved
