Power Connections; Ac200 To 230V Single-Phase Specifications; Power Capacity - Yamaha RCX40 User Manual

4. Power connections

Connect round crimp terminals to the power cable and screw them to the terminal block on the front
panel of the controller as shown below.
c
CAUTION
Before connecting the power cable, be
sure to check that the power supply
voltage matches the power
specifications of your controller.

WARNING
• To prevent electrical shocks
or faulty operation caused by
noise, the earth terminal
(protective conductor) must
be grounded properly.
• To prevent electrical shocks,
never touch the AC IN
terminals when power is
supplied to the robot
controller.
c
CAUTION
The power supply voltage for the
robot controller must always be
regulated within ±10%. If the voltage
drops, the robot controller may issue
an abnormal voltage alarm causing
the robot to trigger emergency stop.
In contrast, operation at a voltage
higher than specified may damage the
robot controller or trigger emergency
stop due to detection of an excessive
motor power supply voltage.
