number 1747-BA). The Battery Low indicator on the LCD display of the
controller shows the status of the replaceable battery. When the battery is low, the
indicator is set (displayed as a solid rectangle). This means that either the battery
wire connector is disconnected, or the battery may fail within 2 weeks if it is
connected.

IMPORTANT The MicroLogix 1400 controller ships with the battery wire connector
connected.
Ensure that the battery wire connector is inserted into the connector
port if your application needs battery power. For example, when using
a real-time clock (RTC).
Replacing the battery when the controller is powered down will lose
all user application memory. Replace the battery when the controller is
powered on.
