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)
All submersible pumps referred to in this manual require 115
V, 60 Hz., single-phase power for
normal operation
.
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, 60 Hz., single phase power via a
power cord to the control box,
ALWAYS
use the correct wire size.
Please reference 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 Figures 3
and 6 and Table 3 to determine the pumping range.

The ST2037, ST2047, ST2047B,
ST2038P, and ST2040T submersible
pumps are also designed to work with
a control box (
Model CB3
). This control
box contains the necessary electronics (float switch
connections) to operate the pump. Remember this 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
!
