For large diameter cables it may be easier to use two smaller cables instead (in order to
allow for a greater flexibility of movement). For example: 2 x 50 mm² instead of 95 mm².

POWER FUSE:
Sizing of fuses for over current protection are a function of the cable sizes in the circuit, not
the amperage drawn by the appliance (thruster motor) in the circuit. It is thus not the electrical
thruster motor that is protected by the fuse, but the power cables supplying the thruster motor.
Considering the importance of selecting the correct
fuse size for your thruster's power circuit and since
incorrect sizing can cause nuisance tripping (to small
fuse) when thruster is really needed or even fire, if fuse
is over sized, it is recommended to use the following
fuses and fuse holders as supplied by Max Power:

for ceramic fuse holder.

BATTERY ISOLATOR:
A manual battery isolator, of the correct size, should be installed in the positive supply cable, as close
as possible to the thruster battery bank and should be easily accessible and clearly marked.
An electrical battery isolator, as supplied by Max Power, should also be installed in the
positive supply cable, as close as possible to the thruster battery bank, in order to benefit
from all automatic safety features of the electronic control system.

OPERATION LIMITATIONS
NEVER navigate at a speed greater than 3 knots when the thruster in the down position.
Please note that the electric motor is rated S2-2 min. This means the motor can run
continuously for 2 minutes, after which it should be stopped for a sufficient time to cool
down to the ambient temperature.
The Compact Retract should always be used when batteries all fully charged with the
engine alternator running. Discharged batteries will damge the motor and / or relay.
