Washington Where is the protection module board on a Bosch SM60?

I believe ours is mounted in the vertical configuration and my son thinks the UPM board is on the bottom and very difficult to get at. I can't really tell from the manual where it is, but you'd think there would just be a removal panel on one of the sides you could get at.
Bosch Water Source Heat Pump Model
Serial: 2940-457-000001-7735019699
SM060-1CFC-SLBATA-EHGXXXXXD7XXXX8XXXXSBA


Each unit is provided with a factory installed Unit
Protection Module that controls the compressor
operation and monitors the safety controls that protect
the unit.

On another SM Bosch unit, the electronics board seems easily accessible.
