IP68 (NEMA 6P)
Battery life @ 0 to 45 °C (32 to 113 °F) typically 5 years
Extended life is possible to give, say, 6 years with a small degradation in response time and slightly increased
measurement uncertainty (contact ABB for details).
Battery life is shorter with GSM, depending on how frequently it is used and for what period. For example, used once
per day for SMS automated reporting of data logged at 15 minute intervals, the life of a battery pack would be typically
reduced to approximately 4 years.

±35 V DC 50mA
Output 1 Forward only, or forward plus reverse pulses
