Quick installation guide
for motor operation with analogue set point
For full instructions please see the Operating and installation manual.
1. Connection of power supply and motor
See
Safety Aspects
and
Installation and Ventilation
•
Connect the power cable’s phase conductors to terminals L1, L2 and L3 in the
inverter. The earth must be connected to PE. See Recommended fuses.
•
Connect the motor cable to terminals U, V and W in the inverter. The earth is
connected to PE. Note if motor is Y or D-connected. A 400V Y/ 230V D motor must
be Y-connected and a 690V Y/400V D must be D-connected.
•
Any thermo contact or thermistor should be connected to terminals 25 and 21. A
resistance of 10 k
Ω
, min 1/4W, must also be connected between terminals 25 and
20.
2. Connecting control signals
•
Connect the analogue control signal to terminal 3 and ground reference to terminal
23 for set point 0/2-10 V, or terminals 10 and 2 for set point 0/4-20 mA.
•
Close terminals 5 and 1 for the start/run signal.
•
The main alarm signal is connected to the fault relay output, terminals 8, 17 and
28. Terminals 17 and 28 are closed upon alarm.
•
Any run indicator is connected to terminals 7, 16 and 27. Terminals 16 and 7 are
closed during operation.
•
The factory setting for the inverter’s set point is 0-10 V. To alter the set point,
change the
AinSet
parameter as per table 7 in the user manual.

WARNING!
If there is a run signal to the inverter (terminals 5 and 1 connected), the
inverter will start at power up. This can be avoided by changing the
AutoSt
parameter.
