Additional Information

Supply Connection – Pluggable System Connection

(Field‑installed cord to equipment terminal block)

Equipment classification
  • This equipment is classified as pluggable equipment when operated from AC mains.
  • This equipment is classified as a mating connection when operated from a DC power source.

Disconnect device

  • AC: The mains plug on the power cord serves as the disconnect device and shall remain readily accessible at all times.
  • DC: A UL approved DC breaker or removable fuse assembly serves as the disconnect device and shall remain readily accessible at all times.

Ratings (per input)

  • AC input: 100–240 VAC, 50/60 Hz, 5 A (×2)
  • DC input: 100–250 VDC, 5 A (×2)

Field‑installed cord and terminal block wiring

The equipment is shipped without a power cord. A suitable power cord shall be field‑installed by a skilled person and connected to the input terminal block according to the terminal markings.
  • Terminal block conductor material: Copper (Cu) only
  • Permitted wire size: 12–18 AWG
  • Minimum tightening torque: 8.68 lb‑in (≈ 1.0 N·m)

Note on classification

The equipment itself uses a field‑installed cord connected to the input terminal block. The pluggable disconnect device is provided at the supply end of the power cord as part of the installation.

AC power cord requirements
  • Use a UL approved power supply cord suitable for the ratings specified above.
  • Minimum conductor size: 18 AWG
  • Minimum temperature rating: 105 °C
  • Flame rating: VW‑1 or equivalent
  • The plug shall comply with the applicable national or regional requirements (e.g. NEMA 5‑15P or NEMA 6‑15P for US/CA; other national plugs as applicable).
  • Route and secure the power cord to prevent mechanical damage and strain at the cord entry.
  • Ensure that the mains plug remains readily accessible after installation.

Power cord length

  • Select the cord length based on the cord construction/type and the defined installation environment (restricted access; wall/ceiling‑mounted or rack‑mounted).
  • The length shall allow proper routing, effective strain relief, and readily accessible disconnection at the plug.

DC power wiring requirements

  • Conductor identification: + (positive), − (negative), and PE (protective earth), as applicable.
  • Minimum conductor size: 18 AWG
  • Minimum temperature rating: 105 °C
  • Flame rating: VW‑1 or equivalent
  • Insulation suitable for the rated DC voltage.

DC power wiring length

  • The wiring length is determined by the selected wire type and the defined installation environment (restricted access; wall/ceiling‑mounted or rack‑mounted).
  • Choose a length that maintains acceptable voltage drop and temperature rise, proper routing and protection, effective strain relief, and easy access to the disconnect device.

Protective earthing (PE)

  • The PE conductor in the AC power cord or DC power wiring (green‑yellow) provides protective earthing to the equipment.
  • Where bonding of the metal enclosure to an external earthing point is required by the installation, bond the enclosure using a UL Listed dual‑hole grounding lug at the designated grounding points with:
    • Two M4 screws
    • 18 AWG (minimum), 105 °C (minimum) grounding conductor
