3.2
Electrical Installation
3.2.1 Voltage Checks
The correct voltage, as specified on the pump data
plate, is necessary for proper performance and long
motor life. Incorrect voltage will decrease the pump's
ability to perform and could cause overheating, reduce
the motor life, and result in higher electric bills.
It is the responsibility of the electrical installer to
provide data plate operating voltage to the pump by
ensuring proper circuit sizes and wire sizes for this
specific application.
CAUTION
Failure to provide data plate voltage (within 10%)
during operation will cause the motor to overheat
and void the warranty.
3.2.2 Bonding and Grounding
1.
The motor frame must be bonded to a reliable
grounding point using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or
larger must be used. If the pump is installed within
five (5) feet of the inside walls of the swimming
pool, spa, or hot tub, the motor frame must be
bonded to all metal parts of the swimming pool,
spa, or hot tub structure and to all electrical
equipment, metal conduit, and metal piping within
5 feet of the inside walls of the swimming pool,
spa, or hot tub.
2.
Bond the motor using the provided
external lug.
WARNING
Always disconnect the power source before working
on a motor or its connected load.

WARNING
Make sure that the control switch, time clock, or
control system is installed in an accessible location,
so that in the event of an equipment failure or a
loose plumbing fitting, the equipment can be turned
off. This location must not be in the same area as the
pool pump, filter, and other equipment.
CAUTION
The pump must be permanently connected to a
dedicated electrical circuit. No other equipment,
lights, appliances, or outlets may be connected to the
pump circuit, with the exception of devices that may
be required to operate simultaneously with the pump,
such as a chlorinating device or heater.
3.2.3 Electrical Wiring
1.
The pump motor must be securely and adequately
grounded using the green screw provided. Ground
before attempting to connect to an electrical power
supply. Do not ground to a gas supply line.
2.
Wire size must be adequate to minimize voltage
drop during the start-up and operation of the
pump. See Table 2 for suggested wire sizes.
3.
Insulate all connections carefully to prevent
grounding or short-circuits. Sharp edges on
terminals require extra protection. To prevent
the wire nuts from loosening, tape them using
a suitable, listed (UL, ETL, CSA) electrical
insulating tape. For safety, and to prevent entry
of contaminants, reinstall all conduit and terminal
box covers. Do not force connections into the
conduit box.
4.
Note the LED on the top of the electronics drive
enclosure (to the lower left of the ePump label).
The LED is lit whenever power is present at the
motor, regardless of whether the motor is running
or not.
NOTE Since the pump is operated by either an ePump
controller (JEP-R), an AquaLink
or an AquaLink
®,
the pump will not be turned on until it is turned
on with one of these controllers.
