The gauge had gained 146.99 points in the previous session on Friday on Reserve Bank Governor Raghuram Rajan's comments that India's exposure to Greece is limited.
In a similar fashion, the National Stock Exchange index Nifty slipped below the 8,400-mark by falling 98.75 points, or 1.16 per cent, to 8,386.15.
Brokers said sentiments on the domestic bourses were adversely affected, triggering selling by participants, largely in tandem with falling trend at other Asian markets after Greek voters rejected more austerity demands from creditors, fuelling fears that the country will crash out of the Eurozone.
