Connecting the
Smart Interrupter
Always switch off the CP
system before connecting
and disconnecting the Smart
Interrupter.
Before connecting
the Smart Interrupter to
the CP supply, measure
the maximum CP voltage.
Ensure that this voltage
is below the Smart
Interrupter’s peak limit
before connecting it.
Peak voltages:
DC 100VDC
AC 70VAC (average or RMS).
Connection to CP voltages
in excess of these limits
may cause damage to the
Smart Interrupter.
When connecting the Smart Interrupter to either the anode
cable or to the structure cable ensure that the red clip is
connected to the most positive connection point and the
black clip to the most negative connection point. If the Smart
Interrupter is connected the wrong way round it will indicate
incorrect connection with a warning tone.
The Smart Interrupter must only be used by suitably
trained personnel.
When connecting the external supply lead, always
connect it to the anode wire before plugging it into the
Smart Interrupter.
