DANGER! High voltage! Risk of electric shock! Only carry out work when the
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 equipment, switching and monitoring devices must comply with the local safety regula
-
tions and established specifications (e.g. VDE) and regulations as well as the manufacturer’s specifica
-
tions.
Motor protection switch is required!
Motor contactors, feed lines, fuses and motor protection
switches must be rated according to the maximum operating current (see name plate).
Use the following overload protection device:
A current-dependent time-delayed overload protection device for monitoring of all three phases, not
set higher than the rated current of the machine, which must respond at 1.2 times the set current
within 2 hours and must not have responded at 1.05 times the set current within 2 hours, or another
comparable device.
