BATTErIES
The 24VDCPS uses 2 AA batteries. Recommended batteries are Lithium (non-rechargeable), Alkaline, or NiMH (rechargeable). To avoid damage by over-dis-
charging, rechargeable batteries should be removed when the Low Battery LED
(
)
illuminates. Non-Rechargeable batteries may continue to be used until
the Red Fault LED
(
)
illuminates, at which time the output voltage will have fallen below 24 V. Lithium batteries are recommended for best performance in
cold weather operations.
