5.3 Terminal cross section for leads
To limit the heating of conducting parts, the minimum terminal cross sections, indicated in the table
have to be followed.
- At ambient temperatures > 40 °C, supply lines and cable/line bushings with a temperature
resistance of at least 90 °C must be used.
- The interpretation of the minimum terminal cross sections refer to the voltage range of 400 V,
50 Hz at 30 °C ambient temperature.
5.4 Connection of the drive
INFO The compressor is equipped with a motor in Y-design.
Operation of the compressor in
∆
switching is not permitted!
ATTENTION Terminal boxes and cable screw connections must be properly
closed. DProtective class IP 66 must be ensured. Use Ex cable screw
fittings (pay attention to correct assignment of the cable and fitting
diameter).
Icing/condensate formation in the terminal box of the compressor
must be avoided due to the danger of short circuits (e.g. through
appropriate suction gas overheating). Carefully set suction gas over-
heating temperature! Check regularly for icing!
