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.
DANGER
Risk of electric shock! High voltage!
Only carry out work when the electrical system is disconnected
from the power supply!
5.1 Information for contactor and motor contactor selection
All protection equipment, switching and monitoring devices must comply with the local safety
regulations and established specifications (e.g. VDE) as well as the manufacturer’s specifications.
Motor protection switches are required!
Motor contactors, feed lines, fuses and motor protection
switches must be rated according to the maximum operating current (see name plate). For motor
protection, use a current-independent, time-delayed overload protection device for monitoring all
three phases. Adjust the overload protection device so that it must be actuated within 2 hours at 1.2
times the maximum working current.
