Fuse at power supply side
Putting the fuse (M) at the positive battery terminal of the power supply, follow the
connection procedure below.
1. Take the black battery cable (O) and fix one side to the short negative battery connection
terminal of the power supply, using an M8 self‑locking nut (K). Tighten with torque 5Nm.
– When the black (O) and red (N) battery cables are fixed to each other, make sure
that the isolated fuse eyelet on the red cable (N) is at the power supply side,
otherwise reverse the complete cable set.
2. Put the fuse (M) on the long positive battery connection terminal of the power supply,
followed by the isolated eyelet of the red cable (N), with the metal side of the eyelet
against the fuse, then followed by a washer (S). Fix this set using the other M8
self‑locking nut (K). Tighten with torque 5Nm.
– The eyelet isolation of cable (N) is needed to prevent that the fuse (M) is being
shorted by the threaded end terminal.
3. Insert the connector of the battery temperature sensor assembly (J) into the temperature
sensor connector socket of the power supply.
