1. Fire prevention
Install the units, motors and regenerative resistor on non-combustible material. Direct installation on
combustible material or near combustible materials could lead to fires.
Always install a circuit protector and contactor on the servo drive unit power input as explained in this
manual. Refer to this manual and select the correct circuit protector and contactor. An incorrect selection
could result in fire.
Shut off the power on the unit side if a fault occurs in the units. Fires could be caused if a large current
continues to flow.
When using a regenerative resistor, provide a sequence that shuts off the power with the regenerative
resistor's error signal. The regenerative resistor could abnormally overheat and cause a fire due to a fault
in the regenerative transistor, etc.
The battery unit could heat up, ignite or rupture if submerged in water, or if the poles are incorrectly wired.
Cut off the main circuit power with the contactor when an alarm or emergency stop occurs.
2. Injury prevention
Do not apply a voltage other than that specified in this manual, on each terminal. Failure to observe this
item could lead to ruptures or damage, etc.
Do not mistake the terminal connections. Failure to observe this item could lead to ruptures or damage,
etc.
Do not mistake the polarity (+,- ). Failure to observe this item could lead to ruptures or damage, etc.
Do not touch the radiation fin on unit back face, regenerative resistor or motor, etc., or place parts (cables,
etc.) while the power is turned ON or immediately after turning the power OFF. These parts may reach high
temperatures, and can cause burns or part damage.
Structure the cooling fan on the unit back face, etc., so that it cannot be touched after installation.
Touching the cooling fan during operation could lead to injuries.
Take care not to suck hair, clothes, etc. into the cooling fan.
