• Make sure that the polarity of the input power supply is correct.
Incorrect polarity may cause damage.
• Always use the specified power supply voltage.
An incorrect voltage may result in fire or malfunction.
• Take appropriate measures to ensure that the input power supply
is supplied within the specified voltage fluctuation range.
An incorrect power supply may result in damage to the equipment.
• Install external breakers or other safety devices against short-cir-
cuiting 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.
• 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 equipment.
• Do not reverse the polarity of the battery when connecting it.
Failure to observe this caution may damage the battery, the SERVO-
PACK or servomotor, or cause an explosion.
• Wiring or inspection must be performed by a technical expert.
• Use a 24-VDC or 48-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 acci-
dent resulting in death or injury. Follow the procedures and
instructions for wiring and trial operation precisely as described
in the relevant manual.
• When using a detector or a breaker for leakage current, select
the appropriate one by considering the grounding conditions and
the leakage current of noise filter. For details, contact the manu-
facturer of the noise filter.
