CAUTION
(1) The generative unit becomes hot during operation. Do not touch it to
avoid burns.
Also do not install the generative unit near an object that is vulnerable
to heat.
(2) When the thermal sensor is activated, an RGU overheat alarm occurs to
stop the robot. If this happens, change the resistor to a larger one or
adjust the deceleration time and/or speed to reduce the braking load
factor.
(3) Always connect the thermal sensor cable to the TEMP connector. Failure
to do so will cause an overheat alarm.
If the generative unit is not needed, plug the shorting connector into the
TEMP connector.
