Module and terminal identification
The MX350 input/output and metering modules are labeled with the “IO_” prefix followed
by a one-character identifier as follows.
Table 1: Input/output and metering module nomenclature
The MX350 terminals are labeled with a two-character identifier. The first character
identifies the module slot position and the second character identifies the terminals within
the module. For example, the first terminal in a module in slot F is identified as “F1”.
NOTE
NOTE:
Do not confuse the slot designation with the module ordering designation. That is, terminal
“F1” does not imply an IO_F module. Rather, it indicates the first terminal of whatever
module is in slot F, which can only be an IO_K module.
