The non-isolated mode only uses one power supply, but has no failsafe feature, since all circuits are lost if the
power supply fails. To connect a single power supply for non-isolated mode:
1 Connect the power supply to either TB3 or TB4.
2 Connect the equivalent pins of the unused terminal block to the active terminal block. This connects the power
source to all slots.
Figure 8. TB3 and TB4 Pin Assignments
Third party wall mount power supplies can be used to provide 48 V power for various plug applications, as shown
in
Table 2 .
* Minimum input power lead wire size current capacity is based on 1000 circular mils per ampere.
