Chapter 1 – Safety precautions
Installation
The following safety precautions are to be observed when installing the frequency inverter:
CAUTION
Be sure to install the inverter on flame resistant material such as metal. Otherwise,
there is a danger of fire.
CAUTION
Be shure not to place anything inflammable in the vicinity. Otherwise, there is a
danger of fire.
CAUTION
Be sure not to let foreign matter (such as cut wire refuse, spatter from welding, iron
refuse, wires, dust etc.) enter the inverter. Otherwise, there is a danger of fire.
CAUTION
Install the inverter in a room which is not exposed to direct sunlight and is well
ventilated. Avoid environments which tend to be high in temperature, high in
humidity or which have dew condensation, as well as places with dust, corrosive
gas, explosive or inflammable gas, grinding-fluid mist, salt damage etc. Otherwise,
there is a danger of fire.
CAUTION
The wall surface on which the inverter is mounted must be of a nonflammable
material, such as a steel plate.
Wiring
WARNING The inverter has to be grounded properly. Otherwise, there is a danger of fire.
WARNING Wiring work must only be carried out when the power supply is off. Otherwise,
there is a danger of electric shock and/or fire.
WARNING Before carrying out the wiring work, the inverter has to be mounted properly.
Otherwise, there is a danger of electric shock or injury.
CAUTION
Make shure that the input voltage is as follows (please also refer to chapter 11):
Single/three phase: 200~240V, 50/60Hz (models up to 2,2kW)
Three phase: 200~240V, 50/60Hz
Three phase: 380~460V, 50/60Hz
CAUTION
Don´t connect AC power supply to the inverter output terminals U, V, and W.
Otherwise, there is a danger of injury and/or fire.

CAUTION
Remarks for using earth leakage circuit breakers in the mains supply:
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a
higher leakage current against earth. Especially in the moment of switching this can
