Transportation
Caution
Please provide storage and transportation under protected conditions.
Do not stack the products too high up to prevent toppling.
The product should be packaged properly during transportation,
Do not hold the product by the cable, motor shaft or encoder while transporting it.
The product should be protected from external forces and shock.
Installation
Caution
Servo drive and Motor:
Do not install around combustibles to prevent fire hazard.
Avoid vibration and impact.
Do not install products that are damaged or incomplete.
Servo drive:
Please install in electrical cabinet with sufficient protection from outside elements.
Reserve sufficient gap as per the installation guide.
Make sure to have good heat sinking.
Avoid dust, corrosive gas, conductive object or fluid and combustibles.
Servo Motor:
Make sure installation is tight to prevent it from loosening.
Prevent fluid from leaking into motor and encoder.
Protect motor from impact to avoid damaging encoder.
Motor shaft should not bear the load beyond the limits as specified.
Wiring
Warning
Participate installation personals should have sufficient training in product installation
safety.
Please power off and wait for 10 minutes to make sure a full discharge of electricity.
Servo drive and motor must be connected to ground.
Connect the cables only after servo drive motor installed correctly

Space requirement for installation
In order to ensure efficient heat dissipation, please leave at least 10mm installation space
in between drivers. If drivers need to be mounted compactly, please leave at 1mm of
installation space. Please keep in mind that under such conditions, the drivers can only
run at 75% of actual load rate.
Installation method
Please install the driver vertical to ground facing forward for better heat dissipation.
Always install in rows and use heat insulation board to separate between rows.
Cooling fans are recommended for drivers to achieve optimal performance.
Grounding
PE terminals must be grounded to prevent electrocution hazard or electromagnetic
interference.
Wiring
Please ensure there is no liquid around the wiring and connectors as liquid leakage
may cause serious damage to the driver(s).
RJ45 port cover
Please cover unconnected RJ45 port(s) on top of the driver to prevent dust or liquid
from damaging the ports.
Battery kit
If there is a need for battery kit, please remember to leave a room in the electrical
cabinet for it.
