How NOT to kill sentinels

Nearly everyone knows to kill these flying robots with plasma. But NEVER use explosive on them(grenades, fuel rods, etc.). An explosion will cause the machinery to overload causing a malfunction similar to the PoA's and destabilizing the machine. It will then release an EMP shockwave, wiping out any energy shields in the area. Unless you are far away or behind a door, your shields will get burned out as well. Not very good if there are enemies around, especially flood.
