INSTALLATION
This is a high performance device designed to provide under-voltage and over-voltage protection for
sensitive electronic circuits and mechanical equipment. Maximum protection will only be achieved if the
device is properly installed. Please read and follow the installation instructions carefully.
NOTICE: This device should be installed by a licensed contractor per the applicable requirements of
the NEC and by using the following instructions.
APPLICATION
This device is designed to be installed in series with a 120/240VAC, 40A max split phase circuit.
Intended line voltages are as follows:
LINE 1 to LINE 2: 208-240VAC LINE 1 to GROUND: 120VAC LINE 2 to GROUND: 120VAC
The mechanical lugs are rated for a wire size range of 14 - 6 AWG Stranded Cu. Rated torque 25 IN. LBS.
The enclosure carries a UL Type 4X rating and is intended to be installed either indoors or outdoors. Make
sure to use appropriate conduit fittings if installing in an outdoor environment.
INSTRUCTIONS:
Caution: Measure all voltages to ensure applied voltage does not exceed the voltage rating of the unit.
Improper installation voids the warranty.
1. Turn off the power to the equipment at the circuit breaker and the disconnect switch before beginning installation.
2. Position the DTK-KG2 between the load side of the circuit breaker or disconnect switch and the equipment.
3. The unit is shipped from the factory with (2) pre-drilled 1/2” NPT holes that will accept non-metallic flexible
conduit male fittings. If desired, the holes can be enlarged to 3/4” NPT using a step drill bit.
Important Note : The conduit holes should always be oriented facing down.
4. Securely mount the unit using all (4) mounting tabs and the appropriate fasteners compatible with the surface
type. Example: Masonry fasteners, concrete anchors or wood screws.
5. Remove the unit cover by loosening the (4) screws located in the corners.
6. Route the conduit from the disconnect switch into one of the pre-drilled holes on the device enclosure.
7. Terminate the (2) phase wires to “LINE 1 IN” and “LINE 2 IN”. Terminate the ground conductor to “GROUND”.
8. Route the conduit from the equipment into the unused pre-drilled hole on the device enclosure.
9. Terminate the (2) phase wires to “LINE 1 OUT” and “LINE 2 OUT”. Terminate the ground conductor to “GROUND”.
10. Replace the lid and securely fasten the (4) screws in each corner.
11. Restore power by turning on the disconnect switch or circuit breaker feeding the equipment. The DTK-KG2 will
enter a startup sequence and will not allow power through to the equipment for approximately 3 minutes.
12. The DTK-KG2 is designed with (2) sets of GREEN and RED LED indicators. The LEDs will blink in various
combinations depending on the condition that the device has detected. The LED color chart referenced on page 2
is intended to serve as a guide for determing the LED combination that corresponds to each voltage condition.
