CHAPTER 3: Installation
3.5.1 P
OWER
C
ONNECTION
The power connection provides mains power. To make this connection, first
attach the IEC 320 female outlet of a standard power cord to the IEC 320
male inlet on the Converter’s rear panel. (This power cord must have a
standard 3-prong plug on the other end.)
WARNING!
BEFORE PLUGGING THIS UNIT INTO AN OUTLET OR OTHER POWER
SOURCE, make sure its protective earth terminals are connected to the
protective conductor of the (mains) power cord. The mains plug must be
inserted only in a socket outlet provided with a protective earth contact.
The protective action must not be negated by use of an extension cord
(power cable) without a protective (grounding) conductor.
If the Converter’s fuse blows, make sure that you replace it only with a
fuse rated for the required amount of current. You must avoid using
repaired fuses or short-circuiting the fuse holders. The fuse, and one
replacement fuse, are located in the top part of the mains connector on
the Converter’s rear panel. The nominal current value of the fuse is 0.125
mA for 230-VAC operation.
Whenever it is likely that the protection offered by the fuse has been
impaired, the unit must be made inoperative and secured against any
unintended operation.
After you have attached the power cord to the unit and have made sure that
the cord is properly grounded, you can plug the power cord into a working
mains outlet.
CAUTION!
The unit has no power switch. It starts operating as soon as AC power is
applied to its POWER connector.
3.5.2 G.703 LINE C
ONNECTION
The G.703 LINE connection provides an interface for the TX and RX signals
between the Converter and G.703 line equipment. To make this connection,
attach the wires from the line equipment to the terminal block on the
Converter this way:
• XMT + (line equipment) to RCV + (Converter);
• XMT – (line equipment) to RCV – (Converter);
• RCV + (line equipment) to XMT + (Converter);
• RCV – (line equipment) to XMT – (Converter);
• Optional: Ground (line equipment) to ground (Converter—the
rightmost terminal).
