Disconnect the lead button connectors from the battery's
positive and negative terminals. Carefully pull the battery
from it retaining clip and remove the battery from the module.
Attach the battery lead button connector to the battery's
positive and negative terminals. Do not use metal tools to
install the battery lead button connector as they may short-
circuit the battery. You should be able to install the connector
without tools.
Carefully press the battery into the module’s battery
retaining clip.
Reinstall the real-time clock communications module in the
controller chassis and perform a voted reset to clear the fault

Safety Considerations
Real-time clock communications modules are TÜV certified
for Risk Class 5 safety applications as non-interfering and can
be used in a safety system for normal data acquisition
functions.
Real-time clock communications modules are approved for
peer-to-peer communications of safety critical data between
two or more Regent systems in Risk Class 5 safety
applications. This requires the use of redundant Guarded
Peer-Link communications networks where the network
connections are made on redundant communications modules
at each Regent.
For additional safety considerations involving
communications with the Regent, refer to the Safety
Considerations Section of the Regent User’s Manual.
