is 2 A or less and the maximum current through any V
SUP
 terminal 
is 1 A or less.
Install a 2 A maximum, fast-acting fuse between the external 
power supply and the V terminal on each channel. The wiring 
diagrams in this document show fuses where appropriate.
Table 1 lists the terminal assignments for the signals associated 
with each channel. The terminal assignments are the same for the 
FP-TB-x terminal bases and the cFP-CB-x connector blocks.
Caution
Do not connect both current and voltage inputs 
to the same channel.
Caution
Cascading power between two modules defeats 
isolation between those modules. Cascading power from 
the network module defeats all isolation between 
modules in the FieldPoint bank.
