WARNING
THE RFL 9508D UCC CHASSIS MUST BE PROPERLY GROUNDED AS
DESCRIBED IN THE FOLLOWING PARAGRAPH BEFORE ATTEMPTING TO
CONNECT INPUT POWER. IMPROPER GROUND CONNECTIONS MAY
RESULT IN SYSTEM MALFUNCTIONS, EQUIPMENT DAMAGE, OR
ELECTRICAL SHOCK.
CHASSIS GROUND CONNECTIONS
A ground stud at the lower right rear of the RFL 9508D UCC chassis is the main ground for the RFL
9508D UCC terminal. This can be seen in Figures 3-3 and 3-4. Grounding is accomplished by
connecting a wire 6AWG or larger between this ground stud and rack ground. The grounding wire
should be kept as short and straight as possible, to keep its resistance and inductance to a minimum.
Before attempting to make power connections, make sure the RFL 9508D UCC terminal is equipped
with a power supply designed to operate at the available input supply voltage. This can be determined
by checking the model designator on the module handle. If an external power supply is being used,
check the markings on the external power supply. If the wrong voltage is connected to the power
supply, component damage will result.
FIBER OPTIC CONNECTIONS
If your RFL 9508D UCC
is equipped with Fiber Optic Modules, fiber optic connectors must be
connected to the fiber optic heads on the rear panel of the 9508D
chassis. Type ST series bayonet fiber
optic connectors (or their equivalent) are used with both singlemode and multimode fibers. The exact
