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. (Figure 37)
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.
