5. Power Connections
Power connections are to the Fast-on type tabs on the end of the board.
The battery connections have one large 9.5mm tab and one small 6.3mm tab. The
small tab is normally used to connect a battery charger or to feed ancillary
equipment.
Each motor connection has two 9.5mm tabs (to feed two motors).
Fully Insulated receptacles must be used to prevent shorts between contacts.
Cable size
Wire of at least 6mm
2
should be used for power connections. Crimps should be
good quality and properly fitted. Undersized wire and poor crimping can cause
overheating and a risk of fire.
Colours shown below are recommended. We recommend that you use different
colours for battery and motor to minimise the risk of connecting a battery wire to a
motor terminal.
Warning: Connecting a battery lead to any motor terminal may damage the
Pro-150.
