4.8 DESCRIPTION OF POWER CONNECTIONS

4.8.1 "Dualac2"

View of the power bars:

-B

Negative of the battery.

+BT

Positive of the battery; if the power fuse is not  present, the positive
cable coming from LC contact must be connected to this power
connection.

+BTF

Positive of battery before power fuse, must be connected to positive
cable coming from LC contact.

Um; Vm; Wm

Connection bars of the three right motors phases; follow this se-
quence and the indication on the motor.

Us; Vs; Ws

Connection bars of the three left motors phases; follow this se-
quence and the indication on the motor.
