 Wiring (cont'd)
• Make sure that the polarity is correct.
Incorrect polarity may cause ruptures or damage.
• Take appropriate measures to ensure that the input power supply is sup-
plied within the specified voltage fluctuation range. Be particularly careful in
places where the power supply is unstable.
An incorrect power supply may result in damage to the product.
• Install external breakers or other safety devices against short-circuiting in
external wiring.
Failure to observe this caution may result in fire.
• Take appropriate and sufficient countermeasures for each form of potential
interference when installing systems in the following locations.
Failure to observe this caution may result in damage to the product.
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields and magnetic fields
• Locations subject to possible exposure to radioactivity
• Locations close to power supplies
Failure to observe this caution may result in damage to the product.
• Wiring or inspection must be performed by a technical expert.
• Use a 24 VDC power supply with double insulation or reinforced insulation
• Failures caused by incorrect wiring or wrong voltage application in the
brake circuit may damage the equipment or cause an accident resulting in
death or injury. Follow the procedures and instructions for wiring and trial
operation precisely as described in this manual.
• Leakage current may increase depending on the type of noise filter and the
grounding conditions.
When using a detector or a breaker for leakage current, select the appro-
priate one by considering the type of noise filter and the ground conditions.
For details, contact the manufacturer of the noise filter.
• Incorrect wiring or incorrect voltage application to the output circuit may
cause short-circuit.
The above failures will prevent the holding brake from working, which may dam-
age the machine or cause an accident resulting in death or injury.
• Inverting the polarity of the brake signal (/BK), i.e. positive logic, will pre-
vent the holding brake from working in case of its signal line disconnection.
If this setting is absolutely necessary, check the operation and confirm that
there are no safety problems.
 Operation
• Do not stand within the machine's range of motion during operation.
Failure to observe this caution may result in injury.
• Always use the linear servomotor and SERVOPACK in one of the specified
combinations.
Failure to observe this caution may result in fire or malfunction.
