SubDrive/MonoDrive
s
CAUTION
!
When increasing the pressure, do not exceed the mechanical stop on the pressure sensor or 80
psi (5.5 bar). The pressure sensor may be damaged.
NOTE: Ensure that the system is properly grounded all the way to the service entrance
panel. Improper grounding may result in the loss of voltage surge protection and
interference filtering.

WARNING
!
Serious oR fatal electrical shock may result from contact with internal electrical components.
DO NOT, under any circumstances, attempt to modify DIP switch settings until power has been
removed and 5 minutes have passed for internal voltages to discharge! Power must be removed
for DIP switch setting to take effect.
Basic Setup (DIP Switches)
For basic set-up, DIP SW1 Position 1 (FE Connect switch) must be in the "OFF" (down)
position for DIP switch and Underload Potentiometer settings to be recognized.
Drive Selection
SubDrives have the ability to perform as MonoDrives when needed (SubDrive15 can be set
as a MonoDrive. SubDrive20 and SubDrive30 can be set as a MonoDriveXT). If you wish
to operate a single-phase motor with a SubDrive unit, ensure that DIP SW1 Position 2 is in
the "ON" (up) position This is indicated by "MD" printed above DIP SW1 Position 2 on the
black shield. If using a SubDrive with a three-phase motor, ensure DIP SW1 Position 2 is in
the "OFF" (down) position, which is indicated by "SD" printed below DIP SW1 Position 2
on the black shield (this is the default setting for SubDrive units).
Note: When operating a SubDrive as a MonoDrive, the MonoDrive pump and motor
specifications on Page 5 apply.
