3.1 Equipment Pre-Installation Checklist

3.1.1 Planning the Installation Site
CAUTION
It is important to plan the installation of the frequency
converter. Neglecting to plan may result in extra work
during and after installation.
Select the best possible operation site by considering
the following:
•
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.

Before unpacking the frequency converter,
examine the packaging for signs of damage. If
the unit is damaged, refuse delivery and
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 that each of the following are rated for
the same voltage:
- Mains (power)
- Frequency converter
- Motor
Ensure that the output current rating is equal to
or greater than the 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
that of the motor, full motor output is
impossible.
