Figure 3-5 Earth/Ground Connection
3.4 Display Backup Module (DBM) – Optional
The DBM is a battery pack containing two 9V Lithium battery clips. This battery pack
provides power to the electronics, but does not power the motor control circuits or the 24
Vdc power supply. When using this option, all latching-type relays on the standard unit and
the Auxiliary Relay Module (ARM) will continue to operate. This option permits testing or
setting up the actuator without applying main power.
The DBM can be provided as an option with the TEC2 or it can be purchased later.
If purchased separate, install as follows. If provided with the TEC2, proceed with
Step No. 2 to activate.
1. Mount the DBM under the Auxiliary Control Module (ACM) on the cover plate
and connect to the Central Control Module (CCM) via a 3-wire cable.
2. Enable battery backup in the setup menu, refer to Section 5,
Customized Actuator Settings.
