SubDrive300 Installation Procedures
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. 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.
3.) Remove the outside cover.
4.) Use the supplied 6 conductor pressure sensor cable to attach the sensor cable to
the sensor. (See Figure 2, pg 10, for Wiring.)
5.) 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.)
