Electrical connections
Important notice
All flail hedge mowers with electrically/electro-hydraulically controlled distributors
(low pressure) and/or heat exchanger, are equipped with electric cables whose
wires are coloured as per current laws in force (see fig. A) (
blue
: positive pole (+)
fixed to
connector no. 58
;
brown
: negative pole (-) fixed to
connector no. 31
) and
of suitable thickness (heat exchanger wire thickness:
2x6 mm
2
; control box wire
thickness:
2x2.5 mm
2
) .
Also, to prevent the inversion of polarity near the terminals, the wires are tagged
with plastic rings bearing the symbols (+) and (-).
When making the connections it is vitally important
NOT TO INVERT THE POLARITY
and
NOT TO ALTER THE WIRE THICKNESS
(risk of burning the electronic components )

-
connect
connector no. 58 (po) (blue wire)
of the socket (
B
), to the
positive pole of the battery
-
connect
connector no. 31 (negative -) (brown wire)
of the socket (
B
), to the
negative pole of the battery
.
2nd case: flail hedge mower with electrical controls only (no heat exchanger)
WARNING
: cable (
C
) which supplies the electrical control box is not supplied by
Ferri, but must
in any case be installed by the customer.
Cable (C)
-
fix the socket (
B
) to the rear part of the tractor frame
-
