INSTALLATION
EN / Alpha alternator - Alpha Pro regulator / June 2007 9
4 INSTALLATION
During installation and commissioning of the Alpha
Alternator and Alpha Pro regulator, the Safety
Guidelines & Measures are applicable at all times.
See section 2 of this manual.
4.1 UNPACKING
In addition to the Alpha Pro alternator the delivery
includes:
• The Alpha Pro regulator
• A cable harness
• A battery temperature sensor;
• This user’s manual + appendix
After unpacking, check the contents for possible
damage. Do not use the product if it is damaged. If
in doubt, contact your supplier.
Check from the identification labels whether the
nominal DC voltage is equal for all applied
components (e.g. a 24V alternator with a 24V Alpha
Pro regulator and a 24V battery set).
4.2 IMPORTANT TO KNOW
Mastervolt alternators offer a much higher output
than alternators usually supplied with engines. As a
result, a single V-belt is insufficient to transfer the
power from the engine to the alternator. Therefore
Mastervolt alternators are standard equipped with a
pulley for two V-belts.
Before installing the pulley ratio between alternator
and main engine need to be checked.
Alternator model Maximum speed:
12/90, 12/130,
24/75, 24/110, 24/150
8000 RPM
24/95 Compact 10000 RPM
Your engine supplier can help you choose an
appropriate double pulley and advise on the bracket
for the alternator.
Note that the alternator support has to be
made suitable for handling the high
forces as well
CAREFUL!
Any changes to the alternator, including
the alternator’s wiring, pulley and/or
mounting points, will make the guarantee
void!
The (remaining) capacity of the engine should be
large enough to drive the alternator. Take into
consideration that the efficiency of a typical
alternator (including transmission V-belt) is
approximately 50%.
Example:
At full output power, the required engine power to
drive Alpha Alternator model 24/75 is:
75 Amps x 28.5V / 50% = 4.3kW
4.3 ENVIRONMENT
Keep the Alpha Pro alternator away from:
• Excessive heat. The maximum alternator
temperature should not exceed 105°C/220°F. An
alternator can become damaged if it operates too
long at excessive temperatures. Damaging heat
levels are generated in two ways: when the
alternator becomes dirty either externally or
internally restricting its ability to dissipate heat
from its external surface or when fresh airflow
through the alternator is restricted.
• Dirt and dust. The alternator operates less
efficiently when buildup of dirt particles form
around wire and cable connections. Dirty
connections impair the flow of electrical current.
• Vibration. If the alternator is poorly or loosely
mounted, the resulting vibration can damage
internal components. A loosely mounted
alternator will also diminish the performance of
the belt drives.
