WARNING
The Fiber Optic Modem has no power switch. Operation starts when you
apply power to the rear panel POWER connector. First, connect the plug
of the power cord to the Fiber Optic Modem POWER connector and then
to the mains power source (outlet).
Grounding
Before switching on the Fiber Optic Modem, connect its protective earth
terminals to the protective conductor of the (mains) power cord. Insert
the mains plug only into a socket outlet with a protective earth contact.
Only use an extension cord (power cord) with a protective conductor
(grounding).
Replace fuses only with fuses of the same current and voltage rating as
indicated on the Modem. Do not short-circuit fuse holders. Whenever it
is likely that the protection offered by fuses has been impaired, make
the Modem inoperative and secure it against any unintended operation.
For your protection, the Fiber Optic Modem must always be grounded.
Interrupting the protective (grounding) conductor (inside or outside the
Modem) or disconnecting the protective earth terminal can make the
modem dangerous. Intentionally interrupting the Modem is prohibited.
AC Power Connection
Supply AC power to the Fiber Optic Modem through the 5-ft. (1.5-m) standard
power cable (included) terminated by a standard 3-prong plug (see
Figure 3-2
).
Connect the power cable to the connector on the Fiber Optic Modem’s rear
panel and then to the mains outlet. The unit will power on automatically when
you connect the cable to the mains.
