ALTERNATOR OpERATORS' hANdbOOk
The alternators are designed for use in a
maximum ambient temperature of 40°C
and altitudes of less than 1000 m above
sea level, in accordance with BS 5000.
In the event that the set is required to
run outside these parameters, refer to
Lister Petter.
The alternators are of air cooled screen-
protected drip-proof design. They are
not suitable for mounting outdoors
unless protected by a weatherproof
canopy. Anti-condensation heaters
are recommended during storage and
standby duty to ensure winding insulation
is maintained in good condition.
The alternator cooling air intake is
through the non-drive end cover.
Installation must be made such that the
intake is not restricted. It is recommended
that a clearance of at least 50mm is
maintained between the alternator air
intakes and any vertical surface. The
terminal box is constructed with easily
removable panels for adaptation to suit
specific glanding requirements. Within
the terminal box, there are insulated
terminals for live and neutral connections
along with earthing provision.
The airflow must not be restricted to

Automatic Voltage Regulation
(See illustration on page 11). The
following jumper connections on the
AVR should be checked to ensure that
they are set correctly for the application.

External hand Trimmer Selection
No external trimmer........... LINK 1-2
Trimmer required. REMOVE LINK 1-2;

High Voltage (220/240V) INPUT no link
Low Voltage (110/120V) INPUT link 3-4
Generator Set Testing
Connect instrument wiring and cabling
required for initial set-up/testing with
permanent connectors.
Minimum instrumentation for testing
should be Voltmeter (L-L or L-N),
Frequency meter, load current meter
and kW meter. If Re-active load is used
a power factor meter is desirable.
WARNING
During testing it may be necessary
to remove covers to adjust
controls, exposing “live” terminals
or components. Only personnel
qualified to perform electrical
service should carry out testing
and/or adjustments.
INITIAL START-Up
Ensure that all engine manufacturers’
initial running procedures have been
followed and that engine governing is
set such that the alternator will not be
subject to speed above 125% of its’
