Connecting A Consumer - VOLTCRAFT AT-50 NV Notice D'emploi

• If the mains plug is plugged in correctly, the green display "L" (3)
will light up.
• If, on the other hand, the red display "N" (2) lights up, you have to
turn the mains plug 180° in the socket (wall socket). This is an
additional protective measure to prevent risks when defective
devices are connected.
If both signal displays light up, this is indication of a
missing earth wire. Do not put the series trans-
former into operation and have the mains socket
checked by a specialist. In case of error, an inter-
rupted earthing wire can be fatal!

Connecting a consumer

Independent of the selection of input voltage, the following output
voltages are always pending at the output sockets:
230V~ on earthing socket (1) and
115V~ US earthing socket (4)
Make sure that the insulation of the connection
cables (mains cables) is not damaged.
Make sure that the consumers are switched off
when being connected to the series transformer.
Sparks may be generated when a switched-on con-
sumer is connected to the jacks. This may damage
the terminal screw connectors as well as the con-
nected cables.
