3.4.2. I/O WIRING
User I/O is connected via TB2 on the internal 3645C2 circuit board. To access
this terminal, the front panels of the unit must be temporarily removed. The
inputs can be driven either from an external 24VDC supply, or from the
internal 24V supply. To use the internal 24V supply, TB2-4 and TB2-5
must be shorted.
No additional I/O wiring is required for running multiple M3645 line regens in
parallel.
