8.2.3 Electrical Connection
Before connecting, you must use HIWIN power cables and encoder cables. Our cables provide a
number of advantages, such as UL/CSA authorization, extreme load capability and resistance as
well as a design suitable for EMC.
Danger! Danger from Electric Voltage!
Work may only be carried out by a qualified electrician and with the power supply
disconnected!
Before carrying out work on the servo motor system, you must disconnect the power
supply and protect it from being switched back on!
Do not remove the cover, cables, or connector from the servo motor while the power is ON.
Do not touch wires or operate the equipment with wet hands.
Do not use when wires are in contact with oil or water.
Before starting to work, check with measuring device whether parts of the servo system
are still under residual voltage. If so, wait until all parts of system have discharged.
Warning! Risk of Personal Injury or Damage to Property.
Before using this product, please read the operation voltage marked in the specification
labels and make sure that the supplied power meets product requirements.
Have professional electricians distributed the wiring.
Make sure the wires distributions execute properly or the servo motor will experience
unexpected reactions.
Please connect the power terminal and motor terminal securely.
When distribute the wiring, the AC servo motor grounding terminal must be installed
properly.
