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

Explosion or Fire Hazard exists if this pump

is used with ﬂ ammable liquids. DO NOT use

this pump with ﬂ ammable liquids. DO NOT

install this pump in hazardous locations as

deﬁ ned 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 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 conﬁ guration. 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 identiﬁ cation

name tag attached to the pump or please contact Multiquip's

Service/Technical Assistance department.

Power Cord Requirements

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.

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.
