The frequency inverter should rest flush against the wall so that the air flow of the
fans is directed through the heat sink.
Make sure to prevent exhaust air produced by other equipment from entering the
device's air intake in order to ensure adequate cooling of the device. The following
minimum distances must be observed:

The power dissipated in the form of heat when the frequency inverter is operated at
nominal duty values varies between 98percent for high power outputs and
95percent for low outputs, depending on the frequency inverter's nominal power.
7.4 Electrical connection
7.4.1 Safety regulations
DANGER
Incorrect electrical installation
Risk of fatal injury due to electric shock!
▷ Always have the electrical connections installed by specialist personnel.
▷ Observe the technical specifications of the local and national energy supply
companies.
DANGER
Unintentional start-up
Risk of fatal injury due to electric shock!
▷ Disconnect the frequency inverter from the mains before carrying out any
maintenance and installation work.
▷ Prevent the frequency inverter from being re-started unintentionally when
carrying out any maintenance and installation work.
DANGER
Contact with live components
Risk of fatal injury due to electric shock!
▷ Never remove the centre housing part from the heat sink.
▷ Mind the capacitor discharge time.
After switching off the frequency inverter, wait 10minutes until dangerous
voltages have discharged.
WARNING
Direct connection between power supply and motor connection (bypass)
Damage to the frequency inverter!
▷ Never establish a direct connection between the power supply and motor
connection (bypass) of the frequency inverter.
