  • Page 100 Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure The enclosure needs to be sealed up tight so don’t be CAUTION stingy with the putty. 17. Put both bags of desiccant inside of the enclosure. 18. Stick the humidity indicator card on a wall inside of the enclosure. Pink on the humidity indicator card means it’s time to CAUTION change the desiccant.
