INSTALLATION INTO CABINET

5.1

GENERAL INFORMATION

The AC drives that are described in this manual have the enclosure class IP00. You must
install them in a cabinet or other enclosure that has a correct level of protection against the
ambient conditions in the installation area. Make sure that the cabinet gives protection
against water, humidity, dust and other contaminations.
The cabinet must also be sufficiently strong for the weight of the IP00 drive module and other
devices. Use a free-standing, floor-mounted cabinet made of sheet metal.
The enclosure class of the cabinet should be at least IP21 / UL Type 1. When you prepare the
installation, obey the local regulations.
