*) For planning and commissioning of new installations use modules in Active
status only.
To ensure propper operation and to prevent data loss, the battery insertion or
replacement must be always done with the system under power. Without battery
and power supply there is no data buffering possible.
Open the battery compartment with the small locking mechanism, press it down and slip
down the door. The door is attached to the front face of the processor module and cannot
be removed.
Remove the TA521 battery from its package and hold it by the small cable.
Insert the battery connector into the small connector port of the compartment. The con-
nector is keyed to find the correct polarity (red = plus-pole = above).
Insert first the cable and then the battery into the compartment, push it until it reaches the
bottom of the compartment.
Arrange the cable in order not to inhibit the door to close.
Pull-up the door and press until the locking mechanism snaps.
