I have a Sound card (Audio Interface) with ‘balanced’ outputs for Left and Right channels. Also I have two reference monitors with balanced XLR inputs. My audio cables have XLR male jacks (to the monitors) and ¼” TS (i.e. not TRS) jacks for soundcard. Further, I removed the cover of the XLR jack and noticed that not all three terminals were used. Only 1 and 3 were (where 1 is for ground and 3 is for the signal, I believe).

Could you please advise whether that these cables can be used to connect the Sound Card and the monitors. I mean, can I use ¼” TS mono jacks with the balanced L&R output channels of sound card? If I use, will it damage any of the equipment (Sound card or Monitors)?

You can use TS mono jacks in TRS balanced outputs but the resulting connection will be unbalanced. The cable wiring you describe, however, sounds weird: leaving 2 open in the XLR connector is a recipe for trouble.

I think you'll be better off getting TRS-to-XLR balanced cables: using balanced connections is your best bet against ground hum and other noise.
