OPERATION
The following procedure outlines the steps for connecting
the pump to a control box.
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.
The CX400 and PX400 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!
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.
The CX400/PX400 submersible pumps require 1Ø, 115
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.
When routing the 115 VAC, 60 Hz., single phase power via
a power cord to the control box, 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.
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.
