installation
Connect
mains power
to terminals
L1, L2, L3
and
PE
.
Connect
motor cable
to terminals
U, V, W
and
PE
using standard unshielded cable.
Never install contactors or switches between the inverter (terminals U, V and W) and the motor that
intentionally or unintentionally may be used to disconnect the motor from inverter output.
A motor safety switch can be mounted between the inverter (terminals U, V and W) and the motor, but it
must only be operated when the motor is not running.
First time powered up, the installer must select application, enter motor name plate data, and perform a
motor tuning.
Connect/install the necessary low voltage signalling that is required for your application, e.g. a run signal for
start/stop, analog input for setpoint, communication, etc.
Make sure run signal is not activated until installer has completed the setup of the inverter.
Make sure the low voltage signal wires have sufficient isolation when passing nearby power cables.
