More penalties after Spa race
Kovalainen made contact with Narain Karthikeyan's HRT in the lap-14 incident. The clash damaged the Caterham's nose, prompting an additional pitstop and contributing to Kovalainen's disappointing 17th-place finish.
Caterham Group chief executive Riad Asmat admitted the team had made a mistake.
"This has been a tough race for the team and it is fair to say we have not helped ourselves with a number of avoidable errors costing us over the weekend," he said.
"The team admitted to the stewards that it considered itself at fault in causing the unsafe release and apologized to HRT accordingly. The stewards did not consider that any sporting advantage was gained."
Also, Pastor Maldonado will be demoted 10 places on the Italian Grand Prix grid as a punishment for both jumping the start in Belgium and colliding with Timo Glock.
He made a premature getaway in the race, before being tagged into a spin as the crash involving Romain Grosjean, Lewis Hamilton, Fernando Alonso and the Saubers unfolded.
Maldonado rejoined, only to collide with Timo Glock's Marussia at the restart, ending his race.
