Supplies Needed - Blue Sea Systems 7608 Mode D'emploi

Supplies Needed

1. DC Wire: Black or yellow for negative, red for each positive.
NOTE: All wiring should be of sufficient length to allow proper routing, support, drip loops, service loops,
and termination.
2. Fuse holders for connection to each battery, for charger negative, and for optional Start Isolation, Combine Batteries
and Remote LED wiring if used (see Full Installation Diagram, page 9).
3. Fuses for fuse holders (see table below and Full Installation Diagram, page 9).
4. Screwdriver: Phillips #2 for mounting screws.
5. Socket wrench (torque wrench preferred): 9/16" deep socket for DC battery positive connections. 7/16" socket for
DC battery negative and DC safety ground connections. Other socket sizes as needed for connection to battery and
fuse holder terminals.
6. Terminals: 3/8" or M10 ring terminals for charger side DC battery positive connections. 1/4" or M6 ring terminals
for charger side DC battery negative and DC safety ground connections. 1/4" x 0.032" female quick connect
terminals for accessory connections. Other ring terminals sized for connection to battery and fuse holder terminals.
7. Appropriately sized butt connectors for extending remote LED and battery temperature sensor wires.
8. Crimping tool or obtain wires that are pre-terminated.
9. Appropriate heat shrink if pre-terminated wires were not acquired.
10. Remote switch for Manual Combine feature if desired. Blue Sea Systems PN 8292 (momentary SPST) or
8282 (non-momentary SPST) suggested.

* Based on 3% voltage drop and 105°C rated wire insulation.
** Fuses in positive wires should be located as close as possible to the battery positive terminal, per ABYC recommendations. If required, the fuse in the negative wire should be located as
close as possible to the charger. Fuse type selected should be verified to have a sufficient amperage interrupt capacity (AIC) for your battery capacity.
