Wiring Instructions - ITT Industries JABSCO 50890 Mode D'emploi

Maintenance
WARNING: Always disconnect pump from
power supply.
Check all electrical connections periodically, particularly in salt
water areas. Corrosion can cause loss of performance or non-
operation in extreme cases. The motor should be protected
with a corrosion inhibiting spray and any rust should be
removed and the motor repainted.

Wiring Instructions

Make all electrical connections in dry locations; connections
in humid environments should be sealed to prevent
corrosion.
Protect the circuit with a rated fuse or circuit breaker in the
red positive (+) lead as close as possible to the power
source.
Connect the black motor wire to the negative (-) battery
terminal.
Inadequate voltage at the motor terminals when the pump
is running (not less than 10% below rated voltage at full
load) due to partially discharged batteries or insufficient
cable size may result in blowing fuses, failure to start or
poor pump performance.

*for longer installations, fit thicker cables
WARNING: If the fuse fails repeatedly do
not fit a heavier fuse or bridge the fuse
terminals with silver paper or metal wire.
Failure to observe this instruction may
result in a fire hazard due to overheating
of cables.
Ensure sterilization of wet end before disassembly.
