Rear Terminal Layout - GE B30 Instruction Manual

CHAPTER 3: INSTALLATION

3.2.3 Rear terminal layout

Do not touch any rear terminals while the relay is energized, else death or serious injury can
result from electrical shock.
Small form-factor pluggable ports (SFPs) are pluggable transceivers. They transmit, receive, and
convert electrical signals to optical signals and vice-versa. They are inserted into the Ethernet ports
on the CPU module. A photo in the Maintenance chapter shows this plug-in device. Do not use non-
validated transceivers or install validated transceivers in the wrong Ethernet slot, else damage can
occur.
The relay follows a convention for terminal number assignments, which are three characters long and assigned 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), indicated by an arrow on the terminal block. The figure shows an example of rear terminal
assignments.
