electrical system is disconnected from the power supply!
INFO!
Connect the compressor motor in accordance with the circuit diagram
(seeinsideofterminalbox).
Use suitable cable entry point of the correct protection type
(see name plate)  for routing cables into the terminal box.
Insert the strain reliefs and prevent chafe marks on the cables.
Comparethevoltageandfrequencyvalueswiththedataforthemains
power supply. Only connect the motor if these values are the same.
5.1 Information for contactor and motor contactor selection
Allprotectiondevicesandswitchingormonitoringunitsmustbettedinaccordancewiththelocal
safetyregulationsandestablishedspecications(e.g.VDE)aswellaswiththemanufacturer’sinfor-
mation. Motorprotectionswitches are required! Motor contactors, feed lines, fuses and motor
protection switches must be rated on the basis of the maximum working current (see name plate).
For motor protection use a current-dependent and time-delayed overload protection device for moni-
toring all three phases. Set the overload protection device so that it must be actuated within 2 hours,
if there is 1.2 times the max. working current.
5.2 Connection of the driving motor
The compressor is designed with a motor for star-delta circuits.

Star-delta start-up is only possible on 230 V voltage supply. Example:
230 V ∆
Direct start Star-delta start
400 V Y
