Also for EMC requirements, a ferrite toroid must be added to the DC input wires. The DC battery
input wires (-48V, -48VRET) must be wound 6 times (6 turns) around a ferrite toroid (Fair-Rite
Products Corporation P/N 2643803802 or equivalent) before the input wires connect to the +V and
-V DC input terminals. The 6 turns must be evenly distributed around the toroid and the toroid must
be located a maximum of 3 inches from the +V and -V DC input terminals. For redundant power
supplies and dual station battery applications, each pair of DC input wires must be wound around a
separate toroid.
Note
For contact information see Fair-Rite Products Corporation's website at www.fair-rite.com.
For a single station battery source:
1. Connect the positive side of the battery to the terminal marked +V on the power supply.
2. Connect the negative side of the battery to the terminal marked -V on the power supply

Craft and Alarm Connections
The System Management Module provides connectors for craft and alarm connections:
• Two DB9 ports (MANAGER and MGR STBY) provide local craft access via an
asynchronous terminal.
• One DB-25F connector is used for contact alarms.
Note
For pinouts and connection parameters on the SMM craft ports and the alarm connector, refer to Chapter 7,
System Management Modules .
