1. Safety
■ Be sure to connect the AC power cable to a power receptacle. DO
NOT connect it directly to a factory power source. To shut off power
to the robot system, pull out the power plug from the power source.
Performing any work while connecting the AC power cable to a factory
power source is extremely hazardous and may result in electric shock
and/or malfunction of the robot system.
■ Before performing any replacement procedure, turn OFF the Controller
and related equipment, and then pull out the power plug from the
power source.

■ Do not insert or pull out the motor connectors while the power to the
robot system is turned ON.
connectors with the power ON is extremely hazardous and may result
in serious bodily injury as the Manipulator may move abnormally, and
also may result in electric shock and/or malfunction of the robot
system.
■ Whenever possible, only one person should operate the robot system.
If it is necessary to operate the robot system with more than one
person, ensure that all people involved communicate with each other
as to what they are doing and take all necessary safety precautions.
■ If the joints are operated repeatedly with the operating angle less than
5 degrees, they may get damaged early because the bearings are
likely to cause oil film shortage in such situation. To prevent early
breakdown, move the joints larger than 30 degrees for about five to ten
times a day.
