Current Switch 3
Publication 1414-IN002A-EN-P - October 2005
Install the Current Switch
Disconnect and lock-out all power sources during installation as severe injury or
death can result from electrical shock due to contact with high voltage conductors.
Ensure all installations are in compliance with applicable electrical codes and that
the installation is completed by qualified installers familiar with the standards and
proper safety procedures for high-voltage installation. Never rely on status
indicating devices only to determine if power is present in a conductor.
Ensure that the output circuit to be switched is within the device switch ratings as
shown in the chart, less than Switch V Max and less than Switch I Max.
Auto-range devices monitor any current over the entire range of Input I Min to
Input I Max Amps as shown in the table.
Install the Split-Core over the conductor to be monitored and close the sensor until
it latches, ensuring that the two halves are properly aligned. Operation of the
sensor will be impaired if any dirt particles prevents good contact between the core
pieces when the device is closed. Keep the sensor clean when it is opened.
Mount the switch in a suitable location using the two mounting holes in the base of
the unit.
The conductor may be looped more than once through the sensor to multiply the
sensitivity but this also divides the maximum current.
Connect the switch circuit to the two screw terminals; bear wire only. Typical
connections are shown in the wiring examples. The switchs are not polarity
sensitive and operate as a ‘dry contact’.
