3.2.2 - Physical and visual checks
Before starting the machine for the rst time, check that:
- the xing 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).
3.3 - Terminal connection diagrams
To modify the connection, change the position of the terminal
cables. The winding code is specied on the nameplate.
Any intervention on the alternator terminals during
reconnection or checks should be performed with
the machine stopped.
