Main Battery Screw Terminals
The main power input can be from 6VDC to 34VDC on a standard RoboClaw and 10.5VDC to 60VDC or 80VDC on an HV
(High Voltage) RoboClaw. The connections are marked + and - on the main screw terminal. The plus (+) symbol marks
the positive terminal and the negative (-) marks the negative terminal. The main battery wires should be as short as
possible.
Do not reverse main battery wires or damage will occur.
Disconnect
The main battery should include a quick disconnect in case of a run away situation and power needs to be cut. The switch
must be rated to handle the maximum current and voltage from the battery. Total current will vary depending on the
type of motors used. A common solution would be an inexpensive contactor which can be sourced from sites like Ebay.
A power diode rated for approximately 2 to 10 Amps should be placed across the switch/contactor to provide a return to
the battery when power is disconnected. The diode will provide the regenerative power a place to go even if the switch is
open.
Motor Screw Terminals
The motor screw terminals are marked with M1A / M1B for channel 1 and M2A / M2B for channel 2. For a typical
dierential drive robot the wiring of one motor should be reversed from the other. The motor and battery wires should be
as short as possible. Long wires can increase the inductance and therefore increase potentially harmful voltage spikes.
