Terminal Block Jumper Combs
Two styles of terminal block jumper combs are available for use with the barrier-style terminal blocks:
ten-position and two position, see Figure 45.
The ten-position jumpers are used with AC output modules to inter-connect L1 (AC Hot) of all channels.
The two-position jumpers are used to connect
Common (DC negative or AC neutral) for the DC
input module, the DC Output Module, and the AC
Input Module. Each of these module types has
groups of eight channels, with the two groups
isolated from each other. The two-position jumper
connects (Common) terminals 10 and 12, making
one group of sixteen non-isolated channels.
The two-position jumper can also be used to connect
the V+ terminals on the DC Output Module.
Refer to the wiring information on each module,
given in this section of this manual.
