Electric Installation; Basic Service Information; Accumulator Battery - Zetor Proxima GP Series Operator's Manual

No additional interventions may be carried out on electric installation of the tractor
(connection of other electric consumers) due to its possible overloading!
With repairs of electric installation pay special attention in particular to manipulation with the battery
to avoid any contact of electrolyte with skin or clothing.

Basic service information

The battery must always be connected with the 'minus'
pole to the ground and with the 'plus' pole to the
alternator. If the battery is connected the other way round,
it will destroy the whole semiconductor equipment of the
alternator. When starting the tractor with the use of an
auxiliary battery, do not forget to connect the terminals
'plus' to 'plus' and 'minus' to 'minus'. If you replace a part
of the charging circuit, disconnect the battery from the
tractor ground (-) with the battery disconnector. This way
you will avoid accidental short-circuits on the terminals.
In case of any handling or repair of the started
motor the minus pole of the battery must be
disconnected and all the shifting levers, incl. the PTO
shifting lever, must be in the neutral position (do not
forget to check whether the locked PTO switches on
the right cabin pillar are off as well to prevent
spontaneous start and endangering of the service
person's life).
It is forbidden to start the engine by short-
circuiting the starter motor terminals. Only start the
tractor from the driver's seat!

Accumulator battery

The battery (1) is installed on the left side, under the
cabin.
The battery disconnector (2) in installed on the left side at
the batter.
a - Battery connected
b - Battery disconnected
In case that the tractor is put out of operation
for a longer period, it is recommended to disconnect
the battery using the battery disconnector. It is
necessary to charge the battery at least each three
months due to its self-discharging.
