UL Approved Wiring Diagram
The following is a UL certified wiring diagram for this module.
Field Wiring
Field wiring to the module consists of separate shielded, twisted pair wires. The acceptable field wire gauge is AWG 20 to AWG 12. Wiring between the module and the intrinsically safe field device should follow intrinsically safe wiring practices to avoid the transfer of unsafe levels of energy to the hazardous area.
NOTE: The tightening torque must be between 0.5 Nm and 0.8 Nm.
NOTICE
DESTRUCTION OF ADAPTER
  • Before tightening the locknut to the torque 0.50...0.80 Nm, be sure to properly position the right-angle F adapter connector.
  • During tightening, be sure to maintain the connector securely.
  • Do not tighten the right-angle F adapter beyond the specified torque.
Failure to follow these instructions can result in equipment damage.
Fixed Wiring System
The Quantum 140 AII 330 10 Intrinsically Safe Current Input module is designed with a fixed wiring system, where the field connections are made to a 40-pin, fixed position, blue terminal strip which is plugged into the module.
Terminal Strip Color and Keying Assignment
The module’s 140 XTS 332 00 field wiring terminal strip is color-coded blue to identify it as an intrinsically safe connector.
The terminal strip is keyed to prevent the wrong connector from being applied to the module. The keying assignment is given below.
