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.
