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
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-5024 is shown below.
