Where do I connect the 24 VAC power wires to on a Spectra HD or Spectra Enhanced

Issue

The only power connector available on the B5-PG-E is labeled for 24VAC, the technical specs say 24VDC is acceptable. Where does the 24VDC connector locate?

Cause

  • The manual lists the power connector as only 24VAC.
  • Installation
  • The Spectra HD supports 24 VDC and 24VAC connections.  When connecting AC, polarity is not an issue and the wire can connect to either terminal.

Resolution

There is a two position terminal block (TB05-9105-0802) located in the back box (as depicted below with the red arrows), when the lower dome drive is removed. See image below.

Either side of the plug can be Positive or Negative as there is no improper polarity to input 24V AC/DC. You will read in the manual that this is for 24VAC, but, this is nevertheless a power input plug in general and does NOT only accept AC voltage.
