5. INSTALLING A MODULE

After installing the TA 850 Base Unit and connecting the required cables, you can install necessary modules.

Individual access modules insert from the front. A locking bar holds the modules in place for added security. Disen-

gaging the captured screw allows removal of the locking bar. All wiring connections terminate on the backplane.

The following step/action table tells how to install a module.

Remove the 20 Hz fuse before exposing backplane or accessing channel units.

Electronic modules can be damaged by static electrical discharge. Before handling modules, wear

an antistatic discharge wrist strap to prevent damage to electronic components. Place modules in

antistatic packing material when transporting or storing. When working on modules, always place

them on an approved antistatic mat that is electrically grounded.
