How to control servo motors using renbotics servo shield and arduino uno

We have attached the library and the datasheet for the servoshield which has been used and we're trying to run the very first in-built example.
Following are the snapshots of our set-up.
We have cross-checked the connections of servo-shield to arduino using jumper wire...
Power requirements have been fulfilled.
Now the problem we are facing is, the moment we connect the power supply, the motor runs momentarily(approx 1 sec) and then it stops.
