Tools and Hardware Required
A Philips screwdriver is required to remove the SubDrive access panel. A crimp tool
may be required for the ¼" quick connects that will attach the aux device to the
relay interface.
For the SubDrive Nema 4 units, excluding the SubDrive300, an Auxiliary Relay
Board is required. An Auxiliary Relay Board kit can be purchased with order
number 225755901.
Serious or fatal electric shock may result from failure to remove electrical power from
the SubDrive prior to installing the relay interface. Disconnect power before working on
the system. Capacitors inside the SubDrive can still hold a lethal voltage for some time
after power has been removed, so allow 10 minutes after removing supply power for
dangerous internal voltage to discharge.
ATTENTION
This equipment is intended for installation only by technically qualified personnel. Failure
to install it in compliance with national and local electrical codes and within Franklin
Electric’s recommendations may result in electrical shock or fire hazard, unsatisfactory
performance, and equipment failure.

Purpose
The tank drawdown kit uses the system run relay and an additional pressure sensor
to allow the use of water stored in the tank during low flow demands.
This setup will allow the drive to control pressure using the regulating sensor to
maintain constant pressure when operating normally. Once the system shuts off,
it will use the stored water in the tank until the pressure drops to the secondary
sensor pressure setting. At that time, the drive will start and regulate to the
regulating pressure sensor pressure setting.

Installation Procedure (For SubDrive300 see pg 6)
1. If the SubDrive is powered, remove power from the drive and wait at least 10
minutes before accessing the drive to ensure that the bus voltage has been given
sufficient time to dissipate.
2. Remove the customer access panel.
ACCESS PANEL
3. Verify Auxiliary Relay Board is installed. If not, please refer to the Auxiliary
Relay Board Instruction Manual M1604 and follow instructions.

4. Add a second 25 to 80 psi sensor to the system. The pressure setting on the
additional sensor will need to be set below the regulating sensor, but above the tank
pre-charge pressure. The pressure can be adjusted once the system is up and running.
5. Use the supplied 6 conductor pressure sensor cable to attach the sensor cable to
the sensor as shown. (See Figure 1, pg 5, for Wiring)
6. Bring the sensor cable into the drive via the knockout at the bottom. (Be sure
to follow local codes requiring conduit or sealing practices. In order to maintain a
NEMA 4 rating, a connector must be used.)

7. Connect the green wire to the pressure sensor (J11) terminal at the SubDrive.
Connect the white wire to the piggyback connector at J11.
8. Connect the Jumper wire to the pressure sensor (J11) terminal and to the
Common (COM) terminal of the Auxiliary Relay Board.
9. Connect the black wire from the cut-in pressure switch to the Normally Closed
(NC) terminal on the Auxiliary Relay Board. Connect the Red wire from the
regulating pressure switch to the Normally Open (NO) terminal on the Auxiliary
Relay Board.

10. The orange and blue wires are not used. Remove terminals and use electrical
tape to insulate.
11. Re-attach the customer access cover.
12. Re-apply power to the drive.
13. Adjust the pressure setting of the low pressure cut-in switch for the
appropriate off time. The pressure setting on the additional sensor will need to be
set below the regulating sensor, but above the tank pre-charge pressure.
