Section 2. INSTALLATION
WARNING
THE RFL 9660 MUST BE PROPERLY GROUNDED AS DESCRIBED IN THIS SECTION BEFORE
ATTEMPTING TO PLACE THE SWITCH IN SERVICE. IMPROPER GROUNDING MAY RESULT IN
SYSTEM MALFUNCTIONS, EQUIPMENT DAMAGE, OR ELECTRICAL SHOCK.
CAUTION
During normal operation, the switching of relay contacts can produce voltage spikes. These spikes
can travel down the relay output leads and induce currents in other leads. These induced currents can
result in corrupted data. To reduce this possibility, use shielded cable for all connections to the
RFL 9660's PORT connectors. Shielded cable should also be used for the connections between the
RFL 9660 and the local DTE when the direct digital interface is used. As an added precaution, do not
bundle data, relay output, and power leads into the same harness - keep them as far apart as
possible.
Before attempting to make power connections, make sure the power switch on the RFL 9125 power
supply module is in the off (down) position. Also, make sure the power supply can operate at the
available station battery voltage. This can be determined by checking the numbers next to the model
designator on the module handle. If you connect the wrong voltage to the power supply, component
damage will result.
2.1 INTRODUCTION
This section contains installation instructions for the RFL 9660, including unpacking, mounting, and wiring.
Figure 2-7 at the end of this section summarizes the information in this section.
2.2 UNPACKING
Each RFL 9660 is packed in its own shipping carton:
1.
Open each carton carefully to make sure the RFL 9660 is not damaged.
2.
After removing the RFL 9660 from the carton, carefully examine all packing material to make sure no
items of value are discarded.
3.
Carefully remove any packing materials inserted into the RFL 9660 to hold circuit board modules in
place during transit.
4.
Make sure all front-panel modules are fully seated in the chassis. The quarter-turn fasteners securing
each module in place should all be in the locked position (screwdriver slots vertical).
If you notice any signs of shipping damage, immediately notify RFL Customer Service at the phone number
listed at the bottom of this page. Save all the packing material and the shipping carton, in case a damage claim
needs to be filed with the shipping company that delivered the unit.
