- The compressors are equipped with a lifting eye or yoke (1-Figs. 1.15 and 1.16).
- When running, the compressor must be installed as level as possible; however, it can be operated

free and well-ventilated place.

The electrical installation must be carried out by an electrician and correspond to the local codes.
The indications on the motor data plate must correspond to the mains supply voltage and frequency. The
installation must include an isolating switch in the power line near to the unit and be protected against
short-circuits by fuses in each phase. See section 2.4.
The mains supply and earthing lines must be of suitable size. See section 2.4.
For DOL starters, connect the power supply cables as shown on Figs. 2.27/2.28. For Y/D starters,
connect the power supply cables to strip (X1-Fig. 2.26) as shown on Figs. 2.29/2.31. Check the setting of
