CAUTION
Any installation using an enclosed cabinet with a swing-out rack must be securely fas-
tened to the floor. This will prevent the cabinet from falling forward when the rack is
moved outward.
5.3.2 INTERCONNECTED CHASSIS INSTALLED IN RACK OR CABINET
Systems mounted in racks or cabinets at the factory are to be placed in position and then bolted to the floor or
wall, as appropriate, to secure the equipment in place. The type of hardware used will depend upon the particu-
lar surface to which the rack or cabinet is being mounted. Because of this, mounting hardware is not supplied
with the rack or cabinet.
5.3.3 INTERCONNECTED CHASSIS MOUNTED ON SHIPPING RAILS
Equipment to be installed in a rack or cabinet at the customer's site is mounted on shipping rails at the factory.
To remove the shipping rails and mount the equipment, proceed as follows:
1. Place the equipment as close to the front of the rack or cabinet as possible. Turn the equipment so the
rear panels face the front of the rack or cabinet.
2. Remove all the screws securing the shipping rails to the equipment.
3. Slide the equipment into the rack or cabinet.
4. Install and tighten screws to all panels to secure the equipment in place.
5.4 VENTILATION
The RFL 9300's specified operating temperature range is as follows:
Horizontal-Mount Chassis: -20
o
C to +60
o
C (-4
o
F to +140
o
F).
Operation at higher temperatures may affect system reliability and performance. RFL 9300 terminals installed in
enclosed cabinets should be ventilated to keep the temperature inside the cabinet within limits.
5.5 ELECTRICAL CONNECTIONS
The following paragraphs describe the electrical connections that must be made when installing the RFL 9300.
The electrical connections consist of the following: connections between the RFL 9300 and the protected line,
communications connections between the local and remote RFL 9300 terminals, and IRIG-B connections.
Rear views of all three RFL 9300 configurations are shown in Figure 5-3. Figures 5-4 and 5-5 are typical
wiring
diagrams that show the electrical connections that must be made between the RFL 9300 and the current trans-
formers on the protected line. Figure 5-6 shows an overview of a typical 2-terminal installation. Figure 5-7
shows an overview of a typical 3-terminal installation. For more details about the connections required in your
application, refer to the "as supplied" drawings furnished with your RFL 9300.
Information is also provided in this section on making modem connections, fiber optic connections, direct digital
connections, and IRIG-B connections. Use the instructions that apply to your equipment, and ignore the rest.
