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 1).
2. Carefully plug the network engine battery connector from the battery compartment into the
connector on the battery cable (Figure 15).
3. Place the battery into the compartment (Figure 15).
4. Slide one end of the battery strap into the hole on the opposite side of the strap (Figure 15),
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.
Note:
The 24 VAC power to the network engine charges the data protection battery. At initial
startup, the battery requires a charging period of at least two hours before it supports data
protection if power fails. Maximum protection (up to three consecutive power failures without
recharging time) requires a 24-hour charging period.
