1.2.2 Precautions for installing the Electric Actuator
(1) Allow ample clearance for teaching the Electric Actuator, maintenance operations and
inspection.
(2) The Electric Actuator controller, other control devices must be installed outside the
Electric Actuator s zone of operation, but within easy access of the operator.
(3) The pressure gauge, oil pressure gauge and other indicators must be located so the
operator can monitor them easily.
(4) Cover electric cables, oil hydraulic lines and pneumatic pipe lines when necessary to
protect them from damage.
(5) Install an emergency stop switch at appropriate locations other than the operator's station.
1.2.3 Precautions for operation of the Electric Actuator
[Operation inside the actuator operating area]
(1) Safety regulations for personnel working in the actuator's operating area
Safety regulations for personnel working in the actuator's operating area should include,
but not be limited to, the following:
1) Basic operations such as starting, stopping and switch handling.
2) Electric Actuator speed during teaching procedures.
3) Communications, including signals, among operators when the Electric Actuator is
operated by more than one person.
4) Emergency procedures to be taken for malfunctions or abnormal operations of the
Electric Actuator.
5) Procedures to be taken for verifying recovery from abnormal conditions and
confirming safety conditions before restarting the Electric Actuator after it is stopped
by an emergency stop device.
6) Procedures to be taken to prevent accidents caused by inattentive operation or
mishandling of the Electric Actuator.
Precautions including notices on all operation switches.
Precautions as needed to assure the safety of personnel in the Electric Actuator’s
area of operation.
The exact location of personnel during work. (This should be determined before
work begins.)
Procedures to be taken to prevent malfunctions arising from electrical noise.
Communications, including signals, between personnel in the actuator operation
area and operators of Electric Actuator and other devices.
Procedures to determine the cause of a malfunction.
7) The safety regulations must be appropriate for the robot type, installation place and
work details, etc.
8) When creating the safety regulations, an effort should be made to obtain the opinions
of the related personnel, manufacturer's engineers and labor safety consultants, etc.
(2) Install notices on Electric Actuator switches to alert personnel that work is underway in
