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

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.
