11. Connect the yellow/green ground cables supplied to the M6 ground
stud on each Gen 3 SC and the EAS/EAS2. Ensure the connection is
tight. Connect the free end of each ground cable to one of the (3)
ground cage nuts present in the rack which the previous modules had
utilized. The ground cage nuts may need to be repositioned if the
cable will not reach. Multiple lugs may not be installed onto a single
nut.
12. Install the remaining cabling per Appendix C of the manual. In
addition, new alarm cables have been provided to route from the
punch blocks to the EAS/EAS2.
13. Reconnect any cabling coming into the rack at the junctional panel.
14. Reconnect the power to the rack by turning all applicable breakers
on.
NOTICE:
Motorola recommends special attention to the following procedures for
successful and safe installation of retrofit Gen 3 Site Controllers.
Note: The complete instructions and wiring diagrams for the retrofit are
contained within this manual.
■ New Rails: The 6 new slide support rails (P/N 0783103X05) are narrower
and allow easier access to the Gen 3 SC connections. The existing rails
should be removed and replaced with these new rails.
■ Do this first: The new ground cables supplied should be connected prior
to connecting power or any connections.
■ Common error: Ensure that the redundancy cable (P/N 3084225N24)
used, is a redundancy cable. As a simple visual aid, the supplied
redundancy cable has yellow bands near each end.
■ New Connection: Be sure to connect the 10/100 Base - T cable (P/N
3082505Y12). It is located at the far right of the rear panels and runs
between the two Gen 3 SCs. This high-speed interface is reserved for
future use.
