The datalogger includes hardware for mounting it to an enclosure backplate
(see Figure 3.1-4). Either a BPALK or PS100 power supply is also typically
housed in the enclosure if a CR800, CR850, or CR1000 is used. These power
supplies also include hardware for mounting them to an enclosure backplate
(see Figure 3.1-4).
