UL Power-limited Wiring Requirements
Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet. All power-limited circuit
wiring must remain at least 0.25” away from any nonpower-limited circuit wiring. Furthermore, all power-limited
and nonpower-limited circuit wiring must enter and exit the cabinet through different knockouts and/or conduits. A
typical wiring diagram for the 411UDAC is shown below.

Note: Relay connections may be power-limited or nonpower-
limited, provided that 0.25" spacing is maintained between
conductors of power-limited and nonpower-limited circuits.
