Installation for Submersible Pump Cutoff
Notice! Only qualified service technicians experienced
with petroleum dispensing and pumping systems
should install the DC400 system.
This controller is NOT for use with
3-phase pumps or Variable Frequency
Drive pump installations.
Notice! Do not exceed the 12 A (continuous), 250 VAC relay
contact rating of this controller. Relay contacts are not
fused. This controller is suitable for most submersible
pumps rated up to 2 hp @ 250 VAC and 1 ½ hp @
120 VAC. provided the maximum pump motor
service factor amperage is 12A or less. Contact the
submersible pump manufacturer if in doubt.
Remove power to avoid possible
electrocution or ignition of explosive
gasoline vapors.
1. Shut off power to the STP. Lock out and tag the
corresponding STP circuit breaker.
2. In pump cutoff installations the 404-4 controller
will be connected directly to the integral electrical
junction box on the STP via rigid explosion proof
conduit. Since STP sump installations can vary,
the installer will need to determine where best to
place the controller in the sump and then procure
the necessary conduit and fittings.
A typical means of connecting the controller to
an STP via an explosion proof union is shown in
Figure 3. All fittings must be UL listed and suitable
for use in a Class I, Div 1, Group D environment.
If the STP junction box does not have a removable plug or
opening, installation adapters are available as listed below.

6. Connect the sensor wire cable coming from the 404-4 controller to the appropriate Franklin Fueling Systems
sensor. Refer to the sensor’s installation instructions for installation, wiring and testing of the sensor.
The sensor must be installed in accordance with the sensor’s control drawing and with Franklin Fueling System’s control
drawing 000-1737.
7. Double check all dispenser & controller power wiring to be sure it is correct then replace the dispenser power
entry junction box cover. Secure the cover with all of the bolts previously retained.
8. Turn the dispenser power back on. The dispenser should operate normally.
9. Replace and secure lower dispenser door(s).
10. Test the DC400 dispenser cutoff by submerging the sensor in water. The dispenser should shut off and remain off
as long as the sensor is submerged.
