Caution in handling

ESNC is for fixed wiring. Do not use for wiring of movable portions.

Minimum bending radius

Please note that excessive bending of cables may deteriorate the characteristics or cause the communication error. To use as exclusive cables for Controller Link, it is recommended to have the bending radius R 60mm or more.

Maximum tensile load

Please note that the conductor could be streched or disconnected if excessive tension is applied to cables when extending, etc.
Please make maximum tensile load for ESNC 0.5 mm² × 1 pair 7 kg or less.

Other notes in wiring Controller Link

  1. Please wire and install ESNC keeping off power line and high voltage cable in order to avoid the influence from noise etc.
  2. Please ground the shield wire of ESNC at the different spot from the drive system device such as inverter etc.
  3. Please make sure to ground at one end, not at both ends.
  4. Please do not wire outdoors. In case outdoor wiring is required, please make sure to take thunderbolt countermeasure such as underground wiring or wiring inside pipe.
  5. Please be careful not to apply load by putting heavy objects etc on ESNC.
