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.
