The output switch of all devices is normally open, when the monitored current exceeds the trip value as set by the multi-turn
adjustment the switch will close. If the unit has a status LED, it will light to indicate a closed switch. Devices that also
feature a power LED will indicate circuit power whenever there is sufficient current flowing in the conductor to
operate the device circuitry, typically 1 Amp minimum for solid-core units and 1.5 Amp minimum for split-core devices.
(See table on next page)
All devices are factory set at the minimum switch point (adjustment fully clockwise). To increase the set point, while
the monitored load is on, turn the adjustment counter-clockwise until the output turns off as indicated by either the
status LED or a voltmeter connected across the device output to indicate an open switch. Then turn the adjustment clockwise
until the LED comes back on to indicate a closed switch or a voltmeter indication is seen. The adjustment should be
turned slightly clockwise past this point to ensure normal line current variations do not cause false conditions. The GNG
series is not adjustable.

Installation
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.
If the device has a selectable range selection jumper, insure it is installed in the correct position for the current being
monitored. Excessive current can damage the sensor. Auto-range devices will monitor any current over the entire range
of Input I Min to Input I Max Amps as shown in the table.
Solid-Core devices require that the line to be monitored be disconnected and routed through the center of the device
while Split-Core units can be easily installed over existing wires without the need to disconnect the circuit.
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 currents.
Connect the switch circuit to the two screw terminals using ring or fork type terminals. Typical connections are shown
in the wiring examples. The switchs are not polarity sensitive and operate as a "dry contact".
