Installation Guidelines

  • The 1756-A17 is designed for horizontal mounting only. Ensure the cabinet provides adequate clearance: 10.2 cm (4.0 in) plus power supply width on the left, 7.7 cm (3.0 in) plus power supply width on the right, 15.3 cm (6.0 in) top clearance, and 5.1 cm (2.0 in) bottom clearance.
  • Secure the chassis using the 10 integrated mounting tabs (5 top, 5 bottom).
  • Grounding: Connect the chassis to a solid Functional Earth (8.3 mm² / 8 AWG) and Protective Earth (2.1 mm² / 14 AWG) to ensure noise immunity and electrical safety.
  • Always power down the system before performing any wiring or maintenance on the backplane or power supply connections.
  • Ensure the environment is free from moisture and contaminants, as this unit does not feature a conformal coating.

FAQs

What is the primary function of the 1756-A17?
