Basic Service Information
Always remove power to the BACnet ATEC when installing or replacing it. Since the
controller does not have a power switch, the recommended method of removing power
to a locally powered controller is to turn OFF the power to the 24 Vac transformer. The
recommended method of removing power to a controller on a power cable (even to
service a single controller) is to turn OFF the power at the transformer.
NOTE:
When removing power to a controller to perform maintenance or service, make
sure that the person in charge of the facility is aware of this and that appropriate
steps are taken to keep the building in control.

Never remove the cover from the BACnet ATEC. There are no serviceable parts
inside. If a problem is found with this device, contact your local Siemens Building
Technologies representative for replacement. An anti-static wrist strap is
recommended when installing or replacing controllers.
Preventive Maintenance
Most controller components are designed so that, under normal circumstances, they
do not require preventive maintenance. Periodic inspections, voltage checks, and point
checks are normally not required. The rugged design makes most preventive
maintenance unnecessary. However, devices that are exposed to dusty or dirty
environments may require periodic cleaning to function properly.
