3.2. Pre-installation
3.2.1. Planning the Installation Site
NOTE
Before performing the installation, it is important to plan the installation of the ad-
justable frequency drive. 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 in the respective Design Guides):
•
Ambient operating temperature
•
Installation method
•
How to cool the unit
•
Position of the adjustable frequency drive.
•
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 adjustable
frequency drive.
•
If the adjustable frequency drive is without built-in fuses, ensure that the external fuses
are rated correctly.
3.2.2. Receiving the Adjustable Frequency Drive
When receiving the adjustable frequency drive, make sure that the packaging is intact, and look
for any damage that might have occurred to the unit during transport. If damage has occurred,
immediately contact the shipping company to make a damage claim.
3.2.3. Transportation and Unpacking
Before unpacking the adjustable frequency drive, it is recommended to unload it as close as pos-
sible to the final installation site.
Remove the cardboard box and keep the adjustable frequency drive on the pallet as long as pos-
sible. Remark: The cardboard box cover contains a drilling master for the mounting holes.
