Installation UL Power-limited Wiring Requirements
2.7 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” (6.35 mm) away from any nonpower-lim-
ited circuit wiring and nonpower-limited circuit wiring must enter and exit the cabinet through dif-
ferent knockouts and/or conduits. A typical wiring diagram for the MS-9200UDLS is shown
below.
