Soc Classification level Abhijit Roy\Ver 0.1 / 12-July-20103 © Nokia Siemens Networks
Flexi System External OVP (FSES) Description
Flexi System External OVP (FSES) protects Flexi BTS modules against surge pulses in power feeding lines between System Module and RF Module.
FSES gives Class II (C, T2) protection for both common and differential mode disturbance for DC power feed between System Module and RF Module.
Protection level UP (differential i.e. Line – Line) < 500 V (at In, 8 / 20 µs).Protection level UP (common i.e. Line – Ground) < 1000 V (at In, 8 / 20 µs).

�STEP 9:Connect the wires to the screw terminal ....
Pay attention to the markings (V48N (-), V48RTN (+) and GND) on the FSES lid toensure correct polarity.
If you have a shielded DC cable, connect the shielding to the terminal marked with GND.Note that the FSES grounding cable has to be connected to the plinth.

�STEP 13:If applicable, connect the alarm cable following the steps in next slidesAlarm output is Normally Open type.
An alarm cable is not included in the FSES delivery. Use an alarm cable that meets the
following requirements:• Minimum wire size 0.5 mm2
• Maximum wire size 2.0 mm2
• Round cable outer jacket diameter must be 8.3 +/- 0.5 mm2• Maximum currect 1.0 mA
