XForce 40/60/75/90/130
NB:
Correct cable bolt nut torque is:
•
Terminal bolt M8 brass: 10 Nm (7.4 lb.ft)
•
Terminal bolt M10 brass: 15 Nm (11.1 lb.ft)
WARNING:
After connecting the cables to the connection bolts with correct torque,
the bolts with cables will still be able to move relative to the terminal plate. To make
sure that no short circuits (contact) between the terminals can occur, the cables
should be secured in such a manner that no short between the terminals can be
caused by movement or vibration. The bolts must be protected by plastic cap nuts or
protective rubber caps.
7.6.1
Motor terminal connections
The terminal bolts are active current leaders.
The pictures show correct connected cables on the motor terminals. Please note that
cable-lug is mounted to the terminal with brass washers on both sides of the cable-
lug, then another washer and nut on top of the cable-lug.
Finally, mount isolating rubber caps or plastic cap nuts. (Not shown on these
pictures).
7.6.2
Connecting the cables to the battery
DANGER!
Make sure that no cables are short-circuited before connecting the battery.
WARNING:
•
The electric power must be turned off during installation.
•
It is recommended to use a dedicated battery bank for high ampere
consumption equipment such as thrusters, or in accordance with the engine
manufacturer’s recommendations.
•
Check all high current connections, tighten where necessary.
•
Connect the plus (+) and minus (-) cables to the correct poles
•
on the battery and the corresponding contacts on the control unit. The plus (+)
cable must be connected via the fuse and main switch.
•
Always turn off the thruster main switch when not in use.
•
All cables between the control unit and the electric motor must be kept as
short as possible. Maximum cable length is 1.5 m (5 ft.) Minimum cable
insulation rating is 105°C (221°F).
