Mechanical Mounting & Grounding Instructions

DIN-Rail and Enclosure Mounting

• Mount the control unit securely onto a standard DIN rail or inside a designated industrial control cabinet enclosure.
• Maintain a minimum clearance of 100 mm around thermal ventilation paths to prevent internal component overheating.

Earthing and Shielding Requirements

• Connect the module to the cabinet protective earth (PE) busbar using a low-impedance flat copper braid or copper busbar; fixing screws alone are insufficient for noise suppression.
• Route fibre optic and 24 VDC power supply cables through segregated wiring channels away from high-voltage motor power lines.

Frequently Asked Questions

• Can the NDCU-11CK drive control unit be hot-swapped while power is active?

  No, input power must be completely shut off before disconnecting or replacing the drive control unit to prevent electrical damage to the internal PCBs.

• What nominal input voltage is required for the control supply?

  The unit operates on a regulated +24 VDC control supply input.

• What auxiliary voltage rails are generated on-board for internal logic?

  The internal power supply provides a regulated +5 VDC rail capable of delivering up to 4 A of current.

• What is the electrical isolation rating of the control circuits?

  The hardware provides 1500 VDC galvanic isolation to protect internal control logic from high-voltage transients.

• What are the allowable operating ambient temperature limits?

  The unit functions continuously within an ambient temperature range of 0 deg C to +50 deg C.

• How should the unit be grounded inside the control cabinet?

  Proper grounding requires a flat copper braid or copper busbar tied directly from the module chassis to the cabinet PE bar.

• What communication accessories are included with the hardware package?

  The delivery package includes two 2-meter fibre optic cables and a dedicated 24 VDC power supply wire set.

• What is the total weight of the standalone control unit module?

  The module weighs approximately 1.25 kg net.
