Setup and Adjustments

Data Protection Battery
The NIE is shipped with the data protection battery installed and connected. Do not disconnect the battery for any
reason other than to replace a defective battery.
The 24 VAC supply power to the NIE charges the data protection battery. At initial startup, the battery may require
a charging period of at least 4 hours before it supports data protection if power fails. Maximum protection (up to 3
consecutive power failures without recharging time) requires a 15-hour charging period.
The data protection battery slowly loses charge when 24 VAC power is removed from the NIE. If the battery completely
loses charge, the NIE real-time clock stops.
Whenever an NIE is disconnected from 24 VAC power for over 30 days, ensure that the real-time clock is set properly
(from the user interface) and that the NIE is powered long enough to recharge the data protection battery.
Powering on the NIE
After applying 24 VAC power, the NIE requires approximately 2 minutes to start up and become operational. See
the LED Test Sequence at Startup
Startup is complete and the NIE is operational when the (green) RUN LED is On steady and the (red) FAULT LED
is Off (Figure 14).
Important: Wait for the NIE to complete the start-up sequence and the RUN LED to go On steady before initiating
any other action on the NIE.
