WARNING
Improper handling
Improper handling may result in serious physical injuries or major
material damage.
To avoid serious physical injuries or major material damage,
only qualified persons may work at the device.
WARNING
Risk of short-circuits and fire
The frequency inverter complies with IP20 ingress protection
rating only if the covers, components and terminals are mounted
properly.
During assembly, make sure that no foreign particles (e.g.
chips, dust, wires, screws, tools) can get inside the
frequency inverter. Otherwise, there is the risk of short
circuits and fire.
Overhead installation or installation in horizontal position is
not permissible.
CAUTION
Risk of short-circuits and fire
Insufficient air circulation could result in major material damage,
which may in turn result in physical injuries.
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.
Fan inlet and outlet openings must not be covered.
