Rear Terminal Layout - GE B30 Instruction Manual

3.1 DESCRIPTION
To properly remove a module, the ejector/inserter clips, located at the top and bottom of each module, must be pulled
simultaneously. Before performing this action, control power must be removed from the relay. Record the original loca-
tion of the module to ensure that the same or replacement module is inserted into the correct slot. While modules with cur-
rent input provide automatic shorting of external CT circuits, for CT/VT modules it is recommended to short/isolate external
circuits accordingly for maximum safety.
To properly insert a module, ensure that the correct module type is inserted into the correct slot position. The ejector/
inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is
smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously.
When the clips have locked into position, the module will be fully inserted.
All CPU modules except the 9E are equipped with 10/100Base-T or 100Base-F Ethernet connectors. These con-
nectors must be individually disconnected from the module before it can be removed from the chassis.
NOTE
3
The 4.0x release of the B30 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.
