DANGER

The ST2037, ST2047, ST2047B, ST2038P, and ST2040T submersible pumps are also designed to work with a control box (Model CB3).Thiscontrol

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!

CAUTION

This control box should only be installed or serviced by a licensed electrician or qualified personnel.

Control Box Mounting

Mountthecontrolboxinanuprightverticalposition.Makesure 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.

CAUTION

Applying incorrect power (voltage phasing) to the submersible pump can cause severe damage to the pump. Please make sure that the correct voltage and phase are transferred to the pump at all times.

Power Cord Requirements

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.
