*Ferrite Beads
AC Power
Grounding Stud
*Ferrite Bead Installation
Per FCC requirements, ferrite beads are required for the DC Power Outputs, Remote Power Supply Sync, ACS Output and SLC Circuit.
Wrap wire around ferrite bead as shown.
MS-9200UDLS PN 52750:A 11/04/05
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.
