7. The critical distance between 2 stationary engines is established by using the following formula: D = 6 + 0.02 × P, where D is the critical distance in metres and P is the capacity in kilowatts of the largest stationary engine. The critical distance does not take into account the walls, floors or other obstacles separating the components of the installation. However, this distance shall not exceed 60 m.
