CONTROL BOX INSTALLATION

Control Box Installation

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

DANGER

The ST4125G and ST6125G submersible pumps are designed to work with a control box.This control box contains the necessary electronics (fl oat 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

CONTROL BOX MOUNTING

Mount the control box in an upright vertical position. Make sure the control box is securely fastened to a fl at 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-4125G/ST6125G submersible pumps require 230 or 460V 3-phase power for normal operation. Each pump is shipped from the factory in the 230 VAC configuration.To change the voltage setting from 230 VAC to 460 VAC refer to the 230/460 VAC voltage selection section (Figure 8).

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 applied to the pump at all times.

Power Cord Requirements

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 defi ned by the National Electrical Code, ANSI/NFPA 70.

When routing the 230/460 VAC, 60 Hz., 3-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.
