Installing and Configuring the HP E1459A 25
Terminal Block
The HP E1459A includes both the input / interrupt module and a screw-type
standard terminal block. User inputs to the terminal block are to the High
and Low for each channel, +5Volt, Ground, Data Valid (DAV0 - DAV3),
External Trigger (XTRIG0 - XTRIG3), and Interrupt (INTR0 - INTR3) .
Figure 1-9 shows the HP E1459A’s standard screw-type terminal block
connectors and associated channel numbers. Use the guidelines below to
wire connections.

Wiring Guidelines •
Be sure the wires make solid connections in the screw terminals.
•
Maximum terminal wire size is No. 16 AWG. When wiring all
channels, a smaller gauge wire (No. 20 or 22 AWG) is recommended.
Wire ends should be stripped 5 to 6 mm (0.2 to 0.25 in.) and tinned to
prevent single strands from shorting to adjacent terminals.
WARNING To prevent the spread of fire in the case of a fault, use
flame-rated field wiring whenever the input voltage will exceed
30Vrms, 42Vpeak, or 60Vdc.
