ONNECTION
The power connection provides AC or DC voltage to the Converter.
To make this connection on the 115-VAC (IC714A) models, first attach the
IEC 320 female outlet of the included power cord to the IEC 320 male inlet
on the Converter’s rear panel.
To make this connection on the 230-VAC (IC714AE) models, first attach the
IEC 320 female outlet of an appropriate power cord to the IEC 320 male inlet
on the Converter’s rear panel. (This power cord must have a plug on the
other end that will fit the site’s mains outlets.)
WARNING!
AC-POWERED MODELS:
BEFORE PLUGGING THIS UNIT INTO AN
OUTLET OR OTHER LIVE POWER SOURCE, make sure its protective earth
contact is 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 (opens), 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 A for 230-VAC operation or 0.25 A for 115-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.
To make this connection on the –48-VDC (IC714A-48) models, first attach the
3-pin DIN jack of an appropriate power cord to the 3-pin DIN plug on the
Converter’s rear panel. (Though an entire cord isn’t included, we do include
the components you’ll need to assemble a 3-pin DIN jack that you can attach
to a cord you build. For more information, consult standard reference works
on cable assembly.)
After you have attached the power cord and have made sure that the cord is
properly grounded, you can plug the power cord into a working mains outlet
(AC models) or DC source (DC model).
CAUTION!
The unit has no power switch. It starts operating as soon as power of the
proper type is applied to its POWER connector.
