Part 4. Power Up Procedures

Where you are instructed to run an MMC program while following these procedures, refer to the
Samsung DCS Combined Programming Manual.

4.1 Connecting Power to the System

During the initial installation, it is best to verify proper system operation before plugging in any am-
phenol-type cables to the MDF. If you have already plugged the cables in, unplug them.
1. Verify that the AC voltage at the outlet is in the range 180 – 270 VAC.
2. Make sure all the AC power switches are in the OFF position.
3. Attach the supplied ferrite core to the power cord (the core is used to suppress electrical interfer-
ence ("noise") in the system):
• Lift the clips on the side of the core and open out the core.
• Position the core at the KSU connection end of the cable, as close to the connector as possible,
and insert the power cord.
• Wrap the power cord once around the core, as shown in the diagram.
•
Close the core firmly and secure the clips.
4. Plug one end of the power cord into the power input connector on the KSU and the other end into
the AC outlet.
5. Confirm that all expansion cabinets are connected to the KSU with both power extension cables
and HDLC cables.
6. Verify that all power switches are in the OFF position.
7. Turn the AC power switch to the ON position on the expansion cabinet(s).
8. Turn the AC power switch to the ON position on the KSU.
