• The electric power supplied to the product must be sufficient satisfying its
power requirements.
Otherwise malfunction could result.
• The power requirements of the 24 VDC external power supply unit supply-
ing input/output contacts depend on the number of the contacts they sup-
ply.
If necessary to provide enough power, install an additional external power supply
unit.
• The motors have their flanges and shaft ends coated with rustproof agent.
Remove the agent with a cloth before installing the motors.
• When coupling a motor with a machine, well align the motor with the
machine.
Failing to do so could cause vibration, resulting in injury or damage.
MANDATORY
CAUTION

Safety precautions
xvi
• Observe the following when designing or installing enclosures (a poorly
designed or installed enclosure for a high-voltage unit could result in dam-
age or malfunction):
• The enclosures must be of hermetic seal type.
• The average temperature rise of the product must be not more than 10 ℃.
• Air stirring fans must be installed within the enclosures to improve cooling
efficiency and prevent local heat buildup (fans should be UL certified).
• Sealing to close cable inlet holes and doors must be effective.
• Displays tend to collect airborne dust and thus malfunction. Therefore their
enclosures must be so designed as to prevent dust intrusion.
• CNC and other units as well as PC boards could malfunction due to accumu-
lated dust. Therefore their enclosures must be so designed as to prevent dust
intrusion.
• Packing must be provided so that cable inlet holes, doors, and back plates are
fully closed.
• Observe the following when installing the units (poorly installed units could
result in damage or malfunction):
• The servo units must be fixed upright using screws or bolts.
• The servo units must be provided with enough space over and under them to
allow them to effectively dissipate their heat.
• Install a servo unit in an enclosure such that the heat sink fins of the unit come
out of the enclosure to keep the unit’s internal temperature lower. The exposed
heat sink fins must be subjected to a 2.5 m/s air draft.
• If an air stirring fan is installed inside an enclosure, the fan must be oriented
such that the air does not directly hit a servo unit (to prevent the servo unit
from collecting more dust).
• Units must be installed such that inspection, replacement and other servicing
activities are easy.
• Do not operate the system if any inverter or converter is physically broken
or otherwise damaged.
Otherwise injury could result.
• When handling the units, hold them by the mounting base, not by the front
cover.
If you hold them by the front cover, the main body could come off the front cover
and might drop onto and injure your foot.
Mount the units to a metal or other non-flammable structure. Otherwise, a fire
could result.
• The maximum operating temperature of 55 ℃must not be exceeded. The
air draft hitting the heat sink must be at not more than 45 ℃.
Note that overheat could result in a burn or a fire.
• An external emergency stop circuit must be provided so that operation
can be stopped and power shut off immediately.
Be aware of a risk of injury.
CAUTION

Safety precautions
xvii
■Wiring
• Shut off power to the product before attempting to work on it.
Otherwise electric shock or a fire could result.
• Wiring work must be done only by qualified personnel.
Otherwise electric shock or a fire could result.
• After wiring work for completing an emergency stop circuit, always check
the circuit for functionality. The customer is responsible for the wiring
work.
Be aware of a risk of injury.
• The grounding terminals must be grounded properly.
Otherwise electric shock or a fire could result.
• Wiring work must be duly done by qualified personnel.
Otherwise electric shock, a fire, or malfunction could result.
• Never apply an AC three-phase power to the U, V, and W output terminals
on a SERVOPACK powering a servo motor.
Otherwise the SERVOPACK would be damaged.
• The capacity and wiring size of customer’s power supply must be so
selected as to satisfy the specific operating conditions and required
capacity. Note that the actual capacity of a cable decreases significantly if
the ambient temperature exceeds 30 ℃. Determine a correct cable size
according to applicable electrical installation regulations and the technical
specifications issued by the cable manufacturer.
Use of a cable of incorrect size could result in a fire.
• Signal cables must be of twist pair, twist-pair multi-strand, or shielded
twist-pair multi-strand type. If a type is specified for signal cables in this
manual, that type must always be used.
Otherwise malfunction could result.
• Cables must be so routed as to be as short as possible.
Otherwise malfunction could result.
• Input or output signal cables must not be bundled together with power
cables or routed in the same wiring duct with power cables inside or out-
side the panels.
Properly separating signal cables from power cables reduces the effect of electric
noise from the power cables on the signal cables.
If electric noise comes into the product along the power line, install a noise filter
at the panel.
WARNING
CAUTION

Safety precautions
xviii
• For information on the required capacity and other specifications of a
noise filter, see the General Documentation - Hardware.
A properly selected noise filter can reduce conducted electric noise significantly.
• Provide the last SERVOPACK module with a terminating connector.
Otherwise malfunction could result.
• Ensure that the voltage of the AC power supply to a converter is equal to
the rated voltage of that converter.
Otherwise injury or a fire could result.
• Do not subject the inverters or converters to a high-voltage withstanding
test.
Otherwise their semiconductor components would be damaged.
• Wiring to the inverters or converters must be done according to the rele-
vant wiring drawing.
Otherwise they could be damaged.
• The screws of a terminal block must be tightened to a specified torque.
Otherwise a fire could result.
• Never connect an AC main power supply to the U/T1, V/T2, and W/T3 out-
put terminals.
