ST-2010 SERIES SUBMERSIBLE PUMPS — CONTROL BOX INSTALLATION
Control Box Mounting
Mount the control box in an
upright vertical position
. Make sure
the control box is securely fastened to a flat surface, that is free
of dust, dirt, moisture or any elements that may contaminate or
erode the electronic components of the control box.
Single-Phase Power Installation (Input)
The ST-2010, ST-2010A, ST-2010CUL, and ST-2010TCUL
submersible pumps require 115 V, 60 Hz., single-phase power
for
normal operation
. The ST-2010B requires 230 V, 60 Hz.,
single-phase power.
If you cannot determine what your pump's power
requirements are, look at the vendor supplied identification
name tag attached to the pump or please contact Multiquip's
Service/Technical Assistance department.
Power Cord Requirements
When routing the 115 VAC/230V, 60 Hz., single phase power via
a power cord to the control box,
ALWAYS
use the correct wire size.
Please refer to Table 4 below (Cord Length/Wire Size) to determine
the correct wire size. Incorrect wire size can adversely affect the
performance of the pump.
Connecting Dual float Switch (SW-1WOP) To Control Box
1.
Remove the float switch input connector housing, then
route the float switch wires through the cable gland on the
control box. Attach the wires of the float switch to the
terminal block as indicated by Table 5 and Figure 6.
2.
Tighten the connector housing to ensure a tight fit between
the cord and the connector body. This will prevent the cable
from pulling out of the terminal block and also prevent
moisture from entering the control box.
3.
Determine the length of the float switch wires, then secure
float switch wires to pump discharge hose. See Figure 5
and Table 3 to determine the pumping range.

The ST-2010 Series submersible
pumps are also designed to work
with a control box. The control box
contains the necessary electronics
(float switch connections) to operate the pump. Remember
the control box contains hazardous voltages. Disconnect
all sources of power before installing or servicing. There
exists the possibility of electrocution, electric shock or
burn, which can cause severe bodily harm or even
death
!
