Andrew Pycroft of the Emirates ICC Elite Panel of Match Referees imposed the sanctions after Quinton de Kock’s side was ruled to be one over short of the target after time allowances were taken into consideration.
De Kock pleaded guilty to the offence and accepted the proposed sanction, so there was no need for a formal hearing.
On-field umpires Adrian Holdstock and Allahudien Paleker, and third umpire Bongani Jele and fourth official Brad White levelled the charges.
