Installation Requirements

See Section Installation, before performing any installation and observe all
warnings.
A common interconnecting cable (6ES7922-3BD00-0AU0 or 6ES7922-3BJ00-
0AU0), supporting six analog input channels, interconnects the analog input
termination assembly to the 6-channel analog input module
(6ES7336-4GE00-0AB0).
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, X100 and X101, for the associated
cable.
Note
To separate channel input low from power supply common, cut and remove the
jumper X300. This will provide isolation between all the inputs and power return.

Maintenance

See Section Maintenance before performing any maintenance and observe all
warnings.
Under normal operation, the A/B Power LED and the Module 1/2 Fuse LED are
on. If all are off, check the power supply to MTA. If the A/B Power LED is off,
check the power supply to the MTA. If the Module 1/2 Fuse LED is off, check the
module fuse and replace as necessary.
Note
Correct power down and power up of the FAI module is crucial to the proper
operation of the system. The proven procedure for removal and re-installation of
the FAI module is as follows:
6. Remove the MTA-I/O cable connector from the FAI module.
7. Remove the FAI module from the backplane.
8. Perform FAI module maintenance as required.
9. Reinstall the FAI module into the backplane.
10. Reinstall the MTA-I/O cable connector onto the FAI module.
