connected to an earth ground. You must have bare metal contact to ensure
good electrical contact between the chassis and the mounting surface.
Remove paint or other non-conductive finishes from the mounting surface
at the point of contact with the chassis mounting bolts (figure 6).
Step 2 – Place keying bands between pins 3 and 4, 9 and 10 on each line
driver/receiver module's slot connector.
Step 3 – Position the module with the male socket on top and insert the
module into the slot.
Step 4 – Seat each module firmly in its connector by applying even
pressure to the edge of the module.
Step 5 – Lock the module in place with the locking tabs.
Complete the following steps before connecting AC line power to the
chassis.
