CALIFORNIA PROPOSITION 65 WARNING:
This product and related
accessories contain chemicals known to the
State of California to cause cancer, birth
defects or other reproductive harm.
POWER SUPPLY:
WARNING: Do not attempt to wire this control box
unless you have a good working knowledge of
electricity and are familiar 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
K4563 11/08/12
from the box. Failure to do so may result in premature
component failure.
Connect incoming power to the terminal blocks per
the included schematic, 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 lation,
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 capac i tor, start relay and run ca pac i tor,
it is critical that the pump leads be connected
prop er ly. The motor main and start winding
leads must be connected to the ap pro pri ate
terminals as directed by the panel schematic
and the pump owner's manual.
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
recom mend ed for the pump.
