with the state and local codes. If
you are in doubt about anything,
contact a qualified electrician.
Do not attempt to operate this unit
on any other voltage or power
distribution other than for which
it was originally designed (check
nameplate). Failure to comply
with this will result in the
immediate cancellation of all
warranties and claims.
It is advisable to put the panel
on its own circuit using a circuit
breaker adequately sized to protect
the pump(s). Check state and local
codes for the correct wire size and
circuit protection to use. The wire
should be sized large enough to
handle the full load current of the
pump(s) you are operating and
any voltage drop that might occur
due to long service runs.
Run power supply lines to the
control box and secure (knockouts
are not supplied in this box).
Select a convenient location on
the bottom to enter the box with
the power supply. Cut a hole with
a chassis punch. Caution should
be taken not to get metal chips
in the components while cutting
hole. After the hole is cut, any
metal particles must be removed
from the box. Failure to do so may
result in premature component
failure.
Connect incoming power to the
terminal blocks labeled L1, L2,
L3, and all necessary ground
wires to the ground lug at the
bottom of the box. The ground
lug should be fastened to a good
driven earth ground by one of
the methods described in the
National Electric Code. NEC
does not permit using ground
as a current-carrying conductor,
therefore a neutral must be
provided for 115 volt 1 phase, 208
volt 1 phase, 230 volt 1 phase, or
208 volt 3 phase systems.
WARNING: Before handling
these pumps and controls,
always disconnect the power
first. Do not smoke or use
sparkable electrical devices or
flames in a septic (gaseous) or
possible septic sump.
Electrical Connections:
The contractor must conform
to the latest requirements of the
National Electrical Code. All
conduit and ca bles shall be in
accordance with NEC Code
NFPA #70. To maintain UL and
CSA ENCL rating, use the same
type UL and CSA weatherproof
con duit hubs when connecting to
this en clo sure. Prior to conducting
any in stal la tion, repair or service
with re gard to the control panel,
refer to the schematic appropriate
for that panel. The schematic will
provide guidance with regard to
the terminal block con nec tions.
CAUTION:
A
nonmetallic
enclosure does not provide
grounding conduit con nec tions.
Use grounding bush ing and
jumper wires.
Make the Following
Electrical Con nec tions:
a. Connect the pump leads to
the control panel. If pump
is single phase and the panel
has start ca pac i tor, start
relay and run ca pac i tor, it is
critical that the pump leads
be connected prop er ly. The
White, Black, and Red pump
leads must be connected to
the ap pro pri ate terminals
as direct ed by the panel
schematic and the label on
the back panel below the
terminals.
b. Connect the pump heat sensor
and seal failure leads (if
available on the pump) to the
appropriate ter mi nal blocks in
the control panel.
c. Connect all the float control
leads or 4-20mA leads to the
appropriate panel terminals.
Contractor must be very
careful in locating the floats
at the proper elevations. The
maximum dis tance from the
control panel to the floats
is the lesser of l00 feet,
or the maximum distance
rec om mend ed for the pump.
d. Before connecting power to the
control panel, make sure all
con trol switches (e.g. H-O-A
switch) and protective devices
(e.g. breakers) are in the Off
po si tion. Now connect power
to the terminal block or the
circuit break er as directed by
the sche mat ic.
e. Control
panel
grounded
properly
NEC and/or local codes. To
facilitate this, a ground lug is
provided on the control panel.
Pump Down
Operation
Pump down is used in situations,
like wastewater lift stations, where
a liquid flows into a tank or well
and must be pumped out. A liquid
flows in the level in the well rises.
The level is continually monitored
by the level transmitter which
sends a 4-20 Ma. signal to the
controller which displays the level
on the first line of the display. If
the level is below the low alarm
setpoint then the low alarm light
and relay are activated.
horn is enabled then it too will be
activated. As the level rises above
the low alarm setpoint the low
alarm condition will be cleared.
When the level rises above the
lead pump on setpoint the lead
pump will be called to run.
Which pump is the lead pump is
determined by the alternator. The
must
be
