Fuses, description
The electrical system has three main circuits (30, 15 and 15E volt-
age), see
Distribution of electricity, description page 10
. The main
circuits are connected across fuses several times with main fuses
and circuit fuses.
Main fuses
Main fuses
1. Control breaker voltage (15E) to control units on
boom and attachment, (25 A)
2. Frame ground connections for boom and attach-
ment, (25 A)
3. Electric power feed relay K1, electric power to ig-
nition voltage (15), (50 A)
4. Battery voltage (30) to cab, engine and transmis-
sion, (50 A)
5. Electric power feed relay K2, electric power to
control breaker voltage (15E), (50 A)
6. Ignition voltage (15) to control units on frame, en-
gine and transmission, (50 A)
The main fuses divide the machine's voltage feed into smaller parts
to maintain as many functions as possible in case of damage to ca-
bles harnesses.
By the cab's and frame's electrical distribution boxes there are fuse
plates that describe the different fuses.
I MP O R T A N T
Risk of cable damage and fire in cable harnesses!
