9. MAKING ELECTRICAL CONNECTIONS
There are electrical connections that must be made to make the
PowerSewer® fully functional.
WARNING
Hazardous voltage can shock, burn or
cause death Failure to disconnect and lock out all electrical power
before attempting installation and maintenance can lead to shock,
burns or death
NOTICE
All electrical connections must be made in
compliance with the National Electrical Code (NEC) ANSI/NF PA70
and local codes
9.1 Cable Specifications
Please see Wiring Diagram for proper connection of the power cable to
the tank junction box and the control panel. The following represents
the minimum specifications for the cable and the specs on the wiring.
Pump Power Cable (PowerSewer® to Control Panel Wiring)
12-gauge, 3-conductor with ground, 60 °C temperature rating,
direct bury, should be connected to the control panel in the enclosure.
It is recommended that a power disconnect be installed if a junction
box is used to provide easy access for power disconnect required
for service.
Local code may require this disconnect. Contact your
municipality for details.
The use of 12-gauge wire is acceptable for distances of less than 125'.
At greater distances, consult the NEC for proper wire size.
9.2 PowerSewer® Pump Power to Control Panel
Excavate trench from the property to the PowerSewer® system a
minimum of 24" deep as required by National Electrical Code, Table
300-5. Remove all rocks and other debris from trench. Uncoil the cable
from the PowerSewer® and lay the cable in bottom of trench. Be sure
to leave a 6" to 12" coil of excess cable at the conduit egress to allow
for ground settling or shifting.
WARNING
Hazardous voltage can shock, burn or
cause death Failure to provide 6" to 12" expansion loop in power
cable can cause fire or damage to the pump control panel or cause
severe personal injury and will immediately void the warranty
Control Panel for Pump Power Wiring Preparation
Strip back the outer jacket of the cable approximately 3", being careful
not to damage the insulation on the individual conductors. Strip back
the insulation on the individual conductors approximately 1/4".
Control Panel Pump Power Wiring Terminals
Refer to control panel wiring diagram and pump owners manual for
wiring instructions.
Control Panel Power Supply Wire Preparation
Strip back the outer jacket of the cable approximately 3", being careful
not to damage the insulation on the individual conductors. Strip back
the insulation on the individual conductors approximately 1/4".
*per appendix wiring diagrams
Control Panel to Property Service Panel
Refer to control panel wiring diagram for wiring instructions.
Property Service Panel Connection
Run the power supply cable from the property service panel to the
Control Panel in compliance with the National Electrical Code (NEC),
ANSI/NF PA70 and other state or local codes.
Refer to pump and control panel wiring to verify required power.
9.3 Control Panel Float Connections
Run the 6-conductor float cable from the tank to the control panel.
Connect the float cable from the tank to the control panel. Refer to the
Wiring Diagram.
Float Connection in the Tank Junction Box
Refer to Wiring Diagram.
WARNING
Hazardous voltage can shock, burn or
cause death Verify required electrical supply power for specific
grinder pump Using the incorrect voltage or phase can cause fire or
damage to the pump motor or cause severe personal injury and will
immediately void the warranty
WARNING
Hazardous voltage can shock, burn or
cause death Failure to properly ground the power connection can
circumvent safety equipment and may shock, burn or cause death
NOTICE
If the terminal labeling is missing or damaged,
refer to the Wiring Diagram for clarification
