Fuse at battery side
Putting the fuse (M) at the positive battery terminal, 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 5
Nm.
– 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
battery side , otherwise
reverse the complete cable set.
2. Take the red battery cable (N) and fix the non‑isolated eyelet to the long positive battery
connection terminal, using the other M8 self-locking nut (K). Tighten with torque 5
Nm.
3. Insert the connector of the battery temperature sensor assembly (J) into the temperature
sensor connector socket of the power supply.
4. Connect the open end of the black cable (O) to the negative battery terminal, with the
eyelet of the temperature sensor (J) on top.
–
Depending on the type of battery and its terminals, use a short M8 bolt (P), spring
washer (R) and washer (S), or short M6 bolt (T), spring washer (V) and washer (W).
– M8 and M6 are the most common screw terminal types for VRLA batteries in PA/VA
applications. Check the battery specification for the optimum tightening torque.
5. Put the fuse (M) on top of the positive battery terminal, then put the open end of the red
cable (N) with the metal side of the isolated eyelet on top of the fuse and fix this set to
the battery terminal with a long bolt, spring washer and washer (M8: Q, R, S / M6: U, V,
W).
