Below 0°C
Temperature
• Installing cold batteries with temperature probes in ambient
temperatures below -10°C may generate a PMN alarm and a Probe
Fail alarm due to a failed temperature probe condition.
• The length of time it will take the batteries to heat up and obtain an
operating state to retire the PMN and Probe Fail alarms depends on
the condition of the batteries, the length of time the batteries were
stored and at what temperature, the batteries’ operating ambient
temperature, and the charging capacity of the plant.
• It is recommended that batteries not be installed in a temperature
below -20°C.
Follow the steps in the tables below to install batteries in the Cabinet
Power System.
