When the clips have locked into position, the module will be fully inserted.
CPU connections must be individually disconnected from the module before the module can be removed from the
The 4.0x release of the L60 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.
The new CT/VT modules can only be used with new CPUs; similarly, old CT/VT modules can only be used with old
CPUs. In the event that there is a mismatch between the CPU and CT/VT module, the relay will not function and a
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.
