User Manual

Motor Terminals M1 and M2
The motor is connected to terminals M1 and
M2 as shown below. If the motor runs in the
opposite way that you want, you may reverse
the motor wires to reverse rotation.
Signal Input Terminals
S1 and S2
The input signals that control the SyRen are
connected to terminals S1 and S2. S1 is the
primary input, and must always be connected.
S2 is the secondary input, and may or may not
be connected, depending on which operating
mode and options you have selected. If you
are running in analog mode, it is important to
have the signal wires to the motor driver
connected before applying power to the
device. Otherwise, the motor may start unexpectedly.
Battery Terminals
B+ and B
The battery or power supply is connected to
terminals B- and B+. B- connects to the
negative side of the battery (usually black.)
B+ connects to the positive side of the battery
(usually red or yellow.) Often it is convenient
to connect the battery through a connector
instead of directly to the motor driver. This
makes it easy to unplug the battery for charging, and prevents plugging in the battery backwards.
Warning! Be very careful to wire and plug in the battery and
connector correctly. Connecting the battery backwards will destroy
the SyRen and will void the warranty.
