Be sure to perform wiring correctly. If there are mistakes in the wiring, the robot may
not stop when the emergency stop button is pressed and there will be a risk of damage
or personal injury occurring.
After wiring, be sure to press each of the installed emergency stop switches and check
whether the emergency stop circuit works properly.
Be sure to duplicate connection of the emergency stop, door switch and enabling
switch. If not duplicated, these functions may fail due to a broken relay used by
customer, etc.
