Electrical Connection
Risk of death, personal injury, or property damage due to explosion, fire,
or electric shock.
•
Follow all electrical connections and for the pump and float switches in the control panel for Class 1
Hazardous environments.
•
Use "intrinsically safe relays" to power the control float switches in Class 1 environments and wet
wells to operate on very low voltage and amperage to eliminate danger of a spark due to power cord
damage.
•
The sensor wiring must be separated from other input wiring by separate conduits or raceways.
Risk of severe injury or death by electrical shock, high temperatures, or
pressurized fluids.
•
To minimize risk of electrical shock, disconnect power before working on or around the system.
•
In a 200-208 and 230 VAC direct wire installation, one side of the line going to the pump is always
electrically energized, regardless of whether the liquid level control switch is open or closed. To
avoid hazards when installing or servicing, install a double-pole disconnect near the pump installa-
tion.
•
The flexible jacketed cord assembly mounted to the pump must not be modified in any way, with the
exception of shortening the cord to fit into a control panel. Any splice between the pump and the
control panel must be made within a junction box mounted outside of the basin and comply with the
National Electrical Code. Employ a licensed electrician.
•
Check the pump label for proper voltage required. Do not connect to voltage other than that shown.
•
Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) device if required by code.
•
The pump should be connected or wired to its own circuit with no other electric receptacles or equip-
ment in the circuit.
•
The fuses or circuit breaker should be of ample capacity in the electrical circuit. For amperage ratings,
refer to
"3" Discharge Models" on page 3
IMPORTANT: Use with approved motor control that matches motor input in full load amperes with
overload element(s) selected or adjusted in accordance with control instructions.
•
Follow the wiring instructions supplied with the control panel. Make proper connections for the heat
sensor, seal fail sensor, level sensing equipment, and thermal and overload protection system(s).
IMPORTANT: Improper wiring or lack of the seal fail sensor, thermal pro-
tection system, and/or the overload protection system to the control panel
will void the warranty and Class 1 listing.
Heat Sensor Wiring
Motor heat sensors open if the motor windings experience excessive heat,
thereby opening the circuit in the control panel and cutting off power to the
pump. The pump automatically restarts when the motor has cooled to an accept-
able temperature.
IMPORTANT: Improper wiring of the heat sensor to the control panel will void the
warranty and Class 1 listing.
Connect the black and white heat sensor leads to the thermal sensor terminals in
the panel.
