Mounting

The BACstat II backplate is designed for mounting directly on a standard North American or European or
Australian electrical box, but may be mounted in other ways as well.

Note 2 below.
Notes:
1. Note that the DNT-T221 has different wiring connections from the DNS-24 and DNT-T103.
2. If wiring 2 or more outputs, you will need a wire nut to terminate all the outputs to GND.
3. Ensure you use the recommended balanced cable for the network and follow documented RS-485 installation
guidelines for MS/TP or LINKnet networks.
4. Do not use 4-wire multi-conductor cable for network and power, as it will not meet the balanced cable
requirements for the MS/TP or LINKnet networks. Use two separate cables: one for the network and the
other for power.
5. Do not terminate the network shield on the BACstats, but ensure shield conductivity is maintained along the
network from end-to-end with wire nuts (i.e., Marrettes™) as necessary.
6. IMPORTANT: Ensure that the network shield and any other bare wires and their connections are all kept in the
wall behind the backplate to ensure that they do not come into contact with the board electronics and cause a
short. Otherwise, you run the risk of damaging the BACstat.
