2.3 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 circuit wiring and
nonpower-limited circuit wiring must enter and exit the cabinet through different
conduits. One such example of this is shown below. Your specific application may
require different conduit knockouts to be used. Any conduit knockouts may be used.
For power-limited applications, use of conduit is optional.
If input circuit wiring
is nonpower-limited, the 24
VDC output on terminals 8 & 9
cannot be used and all wiring
must be run in conduit.
