ST-4125D/ST-6125D Control BOX Installation

ST-4125D/ST-6125D — CONTROL BOX INSTALLATION

DANGER - Hazardous Voltage

To place the ST-4125D/ST6125D submersible pumps into operation requires the use of a control box. The control box contains the necessary electronics (thermal overload module, float switch connections and 230/460 voltage transformer) 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 - Installation

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.

3-Phase Power Installation (Input)

The ST-4125D/ST6125D submersible pump requires 230/ 460V 3-phase power for normal operation.The pump is shipped from the factory in the 230 VAC configuration. To change the voltagesettingfrom230 VACto460VACrefertothe230/460VAC Selection section.

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 - Voltage Phasing

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

When routing the three phase power via a power cord to the controlbox,ALWAYSusethecorrectwiresize.Pleasereference Table 3 below (Cord Length and Wire Size) to determine the correct wire size. Incorrect wire size can adversely affect the performance of the pump.

FLOAT SWITCH INSTALLATION

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 to the float switch terminal block as indicated by Table 4. Refer to Figures 7 and 8.

	STOP	TERMINALS 3 AND 4

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.
