Setup and adjustments
Installing the data protection battery
Important:
Do not apply 24 VAC power to the
network engine before installing the data protection
battery.
To install the data protection battery:
1. Remove the battery from its packaging. Remove the
battery cover on the network engine to expose the
battery compartment (Figure 3).
2. Carefully plug the network engine battery connector
from the battery compartment into the connector on
the battery cable (Figure 16).
3. Place the battery into the compartment (Figure 16).
4. Slide one end of the battery strap into the hole on
the opposite side of the strap (Figure 16), and loop
the strap tightly around the battery to minimize
battery movement.
5. Replace the cover of the battery compartment.
Important:
The data protection battery must
maintain a small residual charge. The battery ships
from the factory with a small residual charge.
You should connect 24 VAC power to the network
engine immediately after connecting the battery to
ensure that the battery does not completely loose its
charge, which may damage the battery.
