3.1 Installation Site 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.
3.1.2 Equipment Pre-Installation Checklist
•
Before unpacking the adjustable frequency drive,
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 adjustable frequency drive,
locate it as close as possible to the final instal-
lation 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:
•
Line power
•
Adjustable frequency drive
•
Motor
•
Ensure the output current rating is equal to or
greater than the motor full load current for peak
motor performance.
•
Motor size and adjustable frequency
drive power must match for proper
overload protection.
•
If adjustable frequency drive rating is
less than that of the motor, full motor
output is impossible.
