3.3.2 - Connection checks
Electrical installations must comply with the
current legislation in force in the country of
use.
Check that:
- the differential 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 blue
wire of the R 791 interference suppression module linking the
neutral and protect the terminal).
- any protective devices in place have not tripped,
- if there is an external regulator, the connections between the
alternator and the cubicle are made in accordance with the
connection diagram,
- there is no short-circuit between phase or phase-neutral
between the alternator output terminals and the generator set
control cabinet (part of the circuit not protected by circuit-
breakers or cubicle relays),
- The earth terminal (ref 28) is connected to the electrical earth
circuit,
- the alternator should be connected with the terminal lugs on
top of one another as shown in the terminal connection
diagrams,
- the equipotential earth links have been implemented correctly
(cross-section and continuity of the earths).
3.4 - Commissioning
The alternator can only be started up and used if the
installation is in accordance with the regulations
and instructions defined in this manual.
The alternator is tested and set at the factory. When first used
with no load, make sure that the drive speed is correct and
stable (see the nameplate). On application of the load, the
alternator should achieve its rated speed and voltage; however,
in the event of abnormal operation, the alternator setting can
be altered (follow the adjustment procedure in section 3.5).
If the alternator still operates incorrectly, the cause of the
malfunction must be located (see section 4.4).
3.5 - Setting up
The various adjustments during tests must be made
by a qualified engineer. The screwdriver for making
adjustments must be suitable for use with electrical
equipment. It is essential that the drive speed
specified on the genset nameplate is reached before
commencing adjustment. The AVR is used to make
any adjustments to the alternator. Access to the AVR
adjustments is via the panel provided for this
purpose.
After operational testing, replace all access panels
or covers.
