• Mechanical checks
Before starting the machine for the first time,
check that:
- all fixing bolts are tight,
- the length of bolt and the tightening torque
are correct,
- the cooling air is drawn in freely,
- the protective grille and housing are cor-
rectly in place,
- the standard direction of rotation is clock-
wise as seen from the drive end (phase
rotation in order 1 - 2 - 3).
For anti-clockwise rotation, swap 2 and 3.
- the winding connection corresponds to the
site operating voltage (see section 3.3).
