UL Power-limited Wiring Requirements Installation
MS-9200UDLS PN 52750:A 11/04/05 35
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-limited circuit wiring and nonpower-limited circuit wiring must
enter and exit the cabinet through different knockouts and/or conduits. A typical wiring
diagram for the MS-9200UDLS is shown below.
