NOTE Interlock terminals
If the N1294A-031 adapter is connected to the Digital I/O connector, the Interlock
terminals are opened. Then the B2961A/B2962A output voltage is limited to 42 V.
To use the interlock function, see “Installing the Interlock Circuit” on page 3-27 and
extend the Interlock terminals. They can be extended from the adapter internal board
