Power Supply—CSA-Approved Units
The CSA-approved MC-III EXP is shipped with either a lithium battery or an alkaline battery pack. Alter-
nately, the MC-III EXP may be powered by an external power source; in this case, the lithium battery or alka-
line battery pack provides a backup power supply, signicantly extending battery service life. A low-power
microprocessor enables the MC-III EXP to operate approximately 2 years on a single lithium battery.
Wiring diagrams for connecting an external power supply are provided in Section 2, page 19.
Power Supply—ATEX-Approved Units
The ATEX-approved MC-III EXP is shipped with a lithium battery. Alternately, the MC-III EXP may be
powered by an external power source; in this case, the lithium battery provides a backup power supply,
signicantly extending battery service life. A low-power microprocessor enables the MC-III EXP to operate
approximately 2 years on a single lithium battery.
