Hello PY,

You may consider using a 4-channel ESD protection circuit on either supply to withstand the Contact and Air voltage requirements. You can place these in parallel with the power supply decoupling capacitors.

Check out the TPD4E101: 4-channel ESD protection with +/-15V contact and air-gap discharge: http://www.ti.com/product/TPD4E101
