CONTROL BOX INSTALLATION
The following procedure outlines the steps for connecting
the pump to a control box.
Each submersible pump is 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!
When installing the control box, the
possibility exists of electrical shock,
electrocution and possibly death!
have untrained personnel perform the
installation. have qualified
service personnel (licensed electrician) perform the
installation.
Explosion or Fire Hazard exists if this pump
is used with flammable liquids. use
this pump with flammable liquids.
install this pump in hazardous locations as
defined by the National Electrical Code,
ANSI/NFPA 70.
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.
Each pump is either configured for 230 or 460 VAC voltage
input. Reference Table 1 for the correct input voltage for
your pump.
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.
When routing the 230/460 VAC, 60 Hz., 3-phase power
via a power cord to the control box, use the
correct wire size. Please refer to Table 5 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.
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.
