Pentomino Scrabble (510)

Place identical pentominoes into the grid. The pentominoes may be rotated and reflected, but they cannot touch each other, not even diagonally. Afterwards, place all the words from the given list into all the remaining (white) cells of the grid so that each word can be read from left to right or from top to bottom in the grid exactly once. All words must be orthogonally connected. No words except the ones listed can appear anywhere in the grid (not even a two-letter word). Some letters are already given.
