Installation
Not Needed = The Second Current Output is Not Needed for this output form and does not have to be
installed. If it is installed, then it can be used to perform an Auxiliary Output function.

NUL2 = Not Used on Loop 2 – This particular output is not used for the selected Second Loop
Output type, but it may be used for the First Loop Output type. Refer to the selection made
in Table 2-6.
N/A2 = Current Duplex 50% is Not Available on Loop 2 unless the Third Current Output is
installed.
Not Needed = The Second Current Output is Not Needed for this Loop 2 Output. If it is installed, and it is
not used for Loop 1 Output, then it can be used to perform an Auxiliary Output function.
Refer to the selection made in Table 2-6.
* The Second Current Output and Ethernet Communications are mutually exclusive.
