Physical and visual checks
3.2.1 -
Before starting the machine for the first time, check that:
- the fixing bolts on the feet are tight
- the cooling air is drawn in freely
- the protective louvres and housing are correctly in place
- the standard direction of rotation is clockwise as seen from
the shaft 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).
Terminal connection diagrams
3.3 -
To modify the connection, change the position of the terminal
cables. The winding code is specified on the nameplate.
Any intervention on the alternator terminals during
reconnection or checks should be performed with
the machine stopped.
