The tram itself would be 2 minutes once your on it. Depending on which gate you arrive it would be about a 3-5 minute normal walk to the tram with luggage in tow... If this was all booked as 1 ticket/connecting option you have no worries as long as starting flight lands on time. They wouldn't have put the connection if it wasn't doable. Being in first helps of course if there is some delays.
