3 - INSTALLATION
Staff undertaking the various operations
indicated in this section must wear per-
sonal protective equipment appropriate
for mechanical and electrical hazards.
3.1 - Assembly
All mechanical handling and lifting
operations must be undertaken using
approved equipment and the machine
must be horizontal. Check how much the
alternator weighs before choosing the
lifting tool.
3.1.1 - Coupling
The GEARLEC or TRACTELEC is coupled
to the agricultural tractor by means of a
universal joint (not supplied). A housing
protects the splined shaft extension at the
alternator end. The universal joint must
incorporate a protective device.
Unsuitable or incorrectly or damaged
fitted universal joint protection can
cause serious accidents.
It is prohibited to park near the alternator
while it is running as the charge demand
may cause the alternator and chassis to
jerk and move.
3.1.2 - TF3 version: TRACTELEC
without chassis
Fix the TRACTELEC securely onto a raised
baseplate for optimum alignment of the
universal joint link with the tractor power
take-off shaft.
3.1.3 - TFM3 version: TRACTELEC
with three-point chassis
The chassis is used to fix the TRACTELEC
to the hitch of any tractor.
Ideally, the TRACTELEC should be placed
on the ground, raising it sufficiently to align
the universal joint link with the tractor power
take-off shaft.
The TRACTELEC should be fixed to the
tractor’s linkage during operation. If
transporting a Mobile TRACTELEC
mounted onto a tractor's three-point
fixing, wedge the reversing rods at the
side to minimise vibrations.
3.2 - Checks prior to first use
3.2.1 - Mechanical checks
Before starting the maching for the first time,
check that:
- the fixing bolts on the feet are tight,
- the coupling is correct, and the universal
joint link is aligned as closely as possible
with the tractor power take-off shaft,
- cooling air is able to enter and exit freely
through the machine vents,
- the protective grilles and housing are
positioned correctly,
- the breather plug pin on the gearbox has
been removed,
- the bearings have been inspected and the
oil level of the gearbox is correct
(see section 4.2).
3.2.2 - Electrical checks
Isolation measures and dielectric tests: see
the alternator’s maintenance manual.
Under no circumstances should an
alternator, new or otherwise, be operated
if the insulation is less than 1 megohm
for the stator and 100,000 ohms for the
other windings.
