3.2.2
Bonding and Grounding
In addition to being properly grounded as described in
the Electrical Wiring section, and in accordance with
the requirements of the National Electrical Code (NEC),
or in Canada the Canadian Electrical Code (CEC),
the pump motor must be bonded to all metal parts of
the swimming pool, spa or hot tub structure and to all
electrical components and equipment associated with
the pool/spa water circulation system.The bonding must
be accomplished by using a solid copper conductor, No.
8 AWG or larger. In Canada No. 6 AWG or larger must
be used. Bond the motor using the external bonding lug
provided on the motor frame. See Figure 8.
National Electrical Code® (NEC®) requires bonding
of the Pool Water. Where none of the bonded pool
equipment, structures, or parts are in direct connection
with the pool water; the pool water shall be in
direct contact with an approved corrosion-resistant
conductive surface that exposes no less than 5800
mm² (9 in²) of the surface area to the pool water at all
times. The conductive surface shall be located where
it is not exposed to physical damage or dislodgement
during usual pool activities, and it shall be bonded in
accordance with the bonding requirements of NEC
Article 680. Refer to locally enforced codes for any
additional bonding requirements.
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.
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.

Installation & Operation Manual
3.2.3
Electrical Wiring
The Jandy pump models covered in this installation and
operation manual provide separate compartments for
high voltage and low voltage wiring.
The low voltage sections provides two (2) 1/2" NPT
conduit ports (threaded). A liquid tight cord grip is
included (see Figure 8).
The high voltage section provides two (2) 1/2" NPT
conduit ports (threaded). Conduit fittings are not
provided (see Figure 9).
1.
Secure the pump 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.
3.
Insulate all connections carefully to prevent
grounding or short-circuits. Sharp edges on
terminals require extra protection. For safety, and to
prevent entry of contaminants, reinstall all conduit
and terminal box covers. Do not force connections
into the conduit box.
NOTE
When power alone is supplied to this pump,
it will not operate. It requires a digital command
sent to it by either a variable speed controller
(SpeedSet, JEP-R, iQPUMP01), or an automation
system (See Figures 8-9 for RS-485 wiring
illustrations for a local controller or automation
system.).
3.2.4
Pump Controller / Automation System
Setup
Pumps in this manual are compatible with the following
local Jandy controllers and automation systems:
• SpeedSet Controller (local)
• iQPUMP01 (local)
• JEP-R (local)
• All Jandy Automation Systems
Each motor is equipped with an auto-sensing power
circuit which automatically determines if 10v of power
should be supplied to the RS-485 wiring in order to
power a local controller interface, or to suppress the 10v
power supply when connected to a Jandy Automation
System.
This auto sensing power circuit eliminates the need for
Dip Switches 1-2 that are present on other Jandy Pumps.
Ensure power to the pump is disconnected and remove
the access cover on the motor. Connect the RS-485
cable through the liquid tight cord grip fitting supplied
as shown in Figure 8. Wire the cable to the RS-485
connector in order Red(1), Black(2), Yellow(3),
Green(4). Secure the access cover back onto the motor
and resupply power.
Refer to the user interface or automation system manual
