3.3.3 - Connection checks
Electrical installations must comply with the current
legislation in force in the country of use.
Check that:
- The residual circuit-breaker complies with 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);
- Any protective devices in place have not tripped;
- If there is an external AVR, 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 alternator has been connected with the busbar separating
the terminals as shown in the terminal connection diagram.
- 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 deîš¿ned in this manual.
The alternator is tested and set in the factory. When îš¿rst used
with no load, make sure that the drive speed is correct and
stable (see the genset 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: see
section 3.5). If the operation is still incorrect, the cause of the
malfunction must be located (see section 4.4 & 4.5).
3.5 - Setting up
The various adjustments during tests must be made by a
qualiîš¿ed engineer. The screwdriver for making
adjustments must be suitable for use with electrical
equipment. It is essential that the drive speed speciîš¿ed
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.
