ALTERNATOR SAFETY RULES

DANGER !

During operation, do not stand in front of the air outlet

guards, in case anything is ejected from them. Do not

allow bystanders or children to stay near the air inlet &

outlet guards.

HANDLING

CAUTION !

The alternator is coming already fitted onto the engine.

The following applies only when alternator has to be

removed for major service.

Fat-sized lifting eyes are for handling the alternator

only. They must not be used to lift the genset. The

choice of lifting hooks or handles should be determined

by the shape of the lifting eyes. Choose a lifting system

in accordance with the integrity and the environment of

the machine.

CAUTION !

Because of the alternator offset center of gravity, keep

the sling horizontal. Do not allow anyone to stand under

the load during operation.

CONNECTIONS CHECKS

CAUTION !

Electrical installations must comply with the current

legislation in force in the country of use. Check that :

- The residual circuit-breaker conforms to legislation on

protection of personnel, in force in the country of use,

and has been correctly installed on the alternator power

output as close as possible to the alternator. (In this

case, disconnect the wire of the interference suppression

module linking the neutral).

- Protection devices in place are on trip position.

- If there is an external AVR, the connections between

the alternator and the cabinet are made in accordance

with the connection picture.

- There is no short-circuit phase-phase or phase-

neutral between the alternator output terminals and

the generator set control cabinet (part of the circuit not

protected by circuitbreakers or relays in the cabinet).

- The machine should be connected with the busbar

separating the terminals as shown in the terminal

connection picture.

- The alternator earth terminal inside the terminal box is

connected to the electrical earth circuit.

- The earth terminal is connected to the frame. The

connections inside the terminal box must never be

subjected to stress due to cables connected by the user.

HOW TO SECURE CABLES

Thightening torque for M10 bolts is : 20 Nm +/-3.
