Rear Terminal Layout - GE D30 Instruction Manual

3.1 DESCRIPTION
The 4.0x release of the D30 relay includes new hardware modules.The new CPU modules are specified with codes
9E and higher. The new CT/VT modules are specified with the codes 8F and higher.
NOTE
The new CT/VT modules can only be used with new CPUs; similarly, old CT/VT modules can only be used with old
CPUs. To prevent hardware mismatches, the new modules have blue labels and a warning sticker stating "Attn.:
Ensure CPU and DSP module label colors are the same!". In the event that there is a mismatch between the
CPU and CT/VT module, the relay will not function and a
played.
All other input and output modules are compatible with the new hardware. Firmware versions 4.0x and higher are
only compatible with the new hardware modules. Previous versions of the firmware (3.4x and earlier) are only com-
patible with the older hardware modules.

Do not touch any rear terminals while the relay is energized!
WARNING
The relay follows a convention with respect to terminal number assignments which are three characters long assigned in
order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the
first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following
figure for an example of rear terminal assignments.
