5.1 Information for contactor and motor contactor selection

All protection equipment, switching and monitoring devices must comply with the local safety reg-
ulations 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 protec-
tion switches must be rated according to the maximum operating current (see name plate). For
motor protection, use a current-dependent, 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.

5.2 Connecting the drive motor

The compressor is equipped with a motor suitable for direct starting.

Risk of electric shock! High voltage!
Only carry out work when the electrical system is disconnected
from the power supply!
Connect the compressor motor in accordance with the circuit diagram
(see inside of terminal box).
Use suitable cable glands 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.
