SAFETY GUIDE
For RSF-B mini series
Read this manual thoroughly before designing the application, installation, maintenance or inspection of the actuator.
Indicates a potentially hazardous situation,
which, if not avoided, could result in death
or serious personal injury.
Indicates a potentially hazardous situation, which, if
not avoided, may result in minor or moderate personal
injury and/or damage to the equipment.

Precautions when using a direct drive motor
CAUTIONS FOR ACTUATORS AT THE APPLICATION DESIGN PHASE
Always use under followings conditions:
•
The motor is designed to be used for indoor.
- Ambient temperature: 0
°
C to 40
°
C
- Ambient humidity: 20% to 80%RH (Non-condensation)
- Vibration:
24.5m/s
2
- No contamination by water, oil
- No corrosive or
explosive gas
Follow exactly the instructions to install the actuator
in the equipment.
•
Ensure exact alignment of motor shaft center and
corresponding center in the application.
•
Failure to observe this caution may lead to vibration,
resulting in damage of output shaft.
CAUTION FOR ACTUATOR IN OPERATION
Keep limited torques of the actuator.
•
Keep limited torques of the actuator.
•
Be aware to balance the gravity for load mounting to
output shaft.
Never connect cables directly to a power supply
socket.
•
Direct drive motor cannot be operated unless it is
connected to dedicated driver.
•
Never connect it to commercial power supply directly.
Direct drive motor may be damaged and causes fire.
Do not apply shocks to actuator.
•
Do not apply shocks because direct drive motor is
directly connected to high precision encoder.
•
If the encoder is damaged, it may cause uncontrollable
operation.
Avoid handling of motor by cables.
•
Failure to observe this caution may damage the wiring,
causing uncontrollable or faulty operation of direct drive
motor.
Precautions when using a driver
CAUTIONS FOR DRIVERS AT APPLICATION DESIGN PHASE
Always use drivers under followings conditions:
•
Mount in a vertical position keeping sufficient distance
to other devices to let heat generated by the driver
radiate freely.
- Ambient temperature: 0
°
C to 50
°
C
- Ambient humidity: less than 90% RH (Non
condensation)
- No vibration or shocks
- No dust, dirt, corrosive, inflammable or explosive gas
Use sufficient noise suppressing means and safe
grounding.
•
Keep signal and power leads separated.
- Keep leads as short as possible.
- Ground actuator and driver at one single point, minimum
ground resistance class: D (less than 100 ohms)
- Do not use a power line filter in the motor circuit.
Pay attention to negative torque by inverse load.
•
Inverse load may cause damages of direct drive motor.
•
Please consult our sales office, if you intend to apply
products for inverse load.
Use a fast-response type ground-fault detector
designed for PWM inverters.
•
Do not use a time-delay-type ground-fault detector.
CAUTION FOR DRIVERS IN OPERATIONS
Never change wiring while power is active.
•
Make sure of power non-active before servicing the
products.
•
Failure to observe this caution may result in electric
shock or personal injury.
Do not touch terminals at least 5 minutes after
turning OFF power
.
•
Otherwise, residual electric charges may result in electric
shock. Wait for 5 min or more before inspection.
•
Make installation of products not easy to touch their inner
electric components.
Do not make a voltage resistance test
•
Failure to observe this caution may result in damage of
the control unit.
•
Please consult our sales office, if you intend to make a
voltage resistance test.
Do not operate control units by means of power
ON/OFF switching.
•
Frequent power ON/OFF may result in deterioration of
internal circuit elements.
•
Start/stop operation of direct drive motor should be
performed via input signals.
DISPOSAL OF DIRECT DRIVE MOTOR, A MOTOR, A CONTROL UNIT AND/OR THEIR PARTS
All products or parts should be disposed of as industrial waste.
•
Since the case or the box of drivers have a material indication, classify parts and dispose them separately.
