Control Box Installation

The following procedure outlines the steps for connecting the pump to a control box.

DANGER

The ST3020B1 and SB3020BCUL submersible pumps are also designed to work with a control box. 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!

DANGER

When installing the control box, the possibility exists of electrical shock, electrocution and possibly death! NEVER have untrained personnel perform the installation. ALWAYS have qualified

service personnel (licensed electrician) perform the installation.

WARNING

Explosion or Fire Hazard exists if this pump is used with flammable liquids. DO NOT use this pump with flammable liquids. DO NOT install this pump in hazardous locations as defined by the National Electrical Code, ANSI/NFPA 70.

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 ST3020B1/BCUL submersible pump requires 1Ø, 230 VAC, 60 Hz, 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 contact Multiquip's service department.

NOTICE

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

Power Cord Requirements

When routing the 230 VAC, 60 Hz., single phase power via a power cord to the control box, ALWAYS use the correct wire size. Please refer to Table 4 to determine the correct wire size. Incorrect wire size can adversely affect the performance of the pump and may ultimately burn-out the pump motor.
