4 Mechanical Installation
The frequency inverters of degree of protection IP20 are designed, as a standard, for
installation in electrical cabinets.
• During installation, both the installation and the safety instructions as well as the
device specifications must be complied with.
Warning! To avoid serious physical injuries or major material damage, only
qualified persons are allowed to work on the devices.
Warning! During assembly, make sure that no foreign particles (e.g. filings, dust,
wires, screws, tools) can get inside the frequency inverter. Otherwise
there is the risk of short circuits and fire.
The frequency inverters comply with protection class IP20 only if the
covers and terminals are mounted properly.
The units may only be used if these requirements are met.
Caution! Mount the devices with sufficient clearance to other components so that
the cooling air can circulate freely. Avoid soiling by grease and air
pollution by dust, aggressive gases, etc.
