3. To prevent injury, note the follow
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with the converter unit and servo amplifier (drive unit) heat sink, regenerative resistor, servo motor, etc.
since they may be hot while power is on or for some time after power-off. Their temperatures may be high
and you may get burnt or a parts may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can cause injury.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric
shock, etc.
(1) Transportation and installation
CAUTION
Transport the products correctly according to their mass.
Stacking in excess of the specified number of products is not allowed.
Do not carry the servo motor by the cables, shaft or encoder.
Do not hold the front cover to transport the converter unit and servo amplifier (drive unit). The converter
unit and servo amplifier (drive unit) may drop.
Install the converter unit and servo amplifier (drive unit) in a load-bearing place in accordance with the

damaged or has any parts missing.
Do not block the intake and exhaust areas of the converter unit, servo amplifier (drive unit) and servo
motor which has a cooling fan. Doing so may cause faults.
Do not drop or strike converter unit, servo amplifier (drive unit), or servo motor. Isolate from all impact
loads.
Securely attach the servo motor to the machine. If attach insecurely, the servo motor may come off during
operation.
The servo motor with reduction gear must be installed in the specified direction to prevent oil leakage.
Take safety measures, e.g. provide covers, to prevent accidental access to the rotating parts of the servo
motor during operation.
Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder
may become faulty.
Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break.
