9.5 Installation Requirements
See Section 2, Installation , before performing any installation and observe all
warnings
A common interconnecting cable (6ES7922-3BD00-0AS0 or 6ES7922-3BJ00-
0AS0), supporting six analog input channels, interconnects the analog input
termination assembly to the 6-channel analog input module (6ES7 336-1HE00-
0AB0, E-Stand 4 or higher). See Figure 2-28.
It may be necessary to modify the printed circuit board as follows:
To disconnect the interconnecting cable shield from ground at the MTA only, cut
and remove the shield disconnect jumper, W100 and W101 , for the associated
cable.
Note
•
To separate channel input low from power supply common, cut and remove
the jumper W200 . This will provide isolation between the all the inputs and
power return.
•
W200 should never be cut when an FAI module is connected to J1 on the
MTA. Doing so will cause the input to exceed the common mode specification
and will generate a common-mode diagnostic error.
