Caution: Do not use the cables provided with the AMPAQ L2/L4 to wire it to experiments that use a different
amplifier module, such as the Quanser Rotary (SRV02) or Linear (IP02) products, as this will result
in burning the motors. The AMPAQ L2/L4 can be used with such experiments only if plant specific
cables are available.
