To install an AquaLink
®
RS controller (Rev O
or later), an AquaLink PDA (Rev 4.0 or later), or an
AquaLink Z4:
1. Remove power from the ePump by disconnecting
the high voltage lines or by opening any breaker to
which the ePump power is connected.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in
the ePump electrical circuit before starting the
procedure. Failure to comply may cause a shock
hazard, resulting in severe personal injury or death.
2. Remove the cover of the ePump junction box and
feed the RS-485 cable into the fitting.
3. Unplug the RS-485 connector from the ePump and
attach the four (4) wires in the RS-485 cable to
the RS-485 connector. Match the wire colors with
the connector positions as follows: 1-red, 2-black,
3-yellow, and 4-green. See Figures 5A and 5B.
5. Insert the RS-485 connector back into the ePump.
6. Slide dip switches 1 and 2 down, so they are in the
OFF position. See Figure 5A and 5B.
7. Select the desired address(es) for the ePump(s)
by setting dip switches 3 and/or 4, as shown in
Section 3.3, ePump Dip Switch Settings.
NOTE
Since the pump is operated by either an ePump
controller (JEP-R), an AquaLink
®
RS controller,
an AquaLink Pool Digital Assistant (PDA) or a
Z4 controller, the pump will not be turned on
until it is turned on with one of these controllers.
3.2.4 Installing the Controller
The ePump can be operated by one of three (3)
controllers: the ePump controller (JEP-R), the AquaLink
RS controller (Rev O or later), the AquaLink PDA (Rev
4.0 or later), or the AquaLink Z4 controller.
The Jandy Pro Series motor model pump comes
equipped with a factory installed four-wire RS-485
cable. This RS-485 cable comes with an additional
shielded wire for grounding. The shielded wire is to
be grounded ONLY at one end, at the Jandy Pro Series
motor model pump. This is pre-installed at the factory.
At the other end, the shielded wire is pretrimmed at
the factory. If you need to cut the RS-485 cable to any
custom length, make sure to peel back and trim the
ground shielded wire. The ePump communicates with
the controllers via a four-wire RS-485 interface.
To install the ePump controller:
NOTE
The ePump controller part no. is JEP-R.
1. Remove power from the ePump by disconnecting
the high voltage lines or by opening any breaker to
which the ePump power is connected.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in
the ePump electrical circuit before starting the
procedure. Failure to comply may cause a shock
hazard, resulting in severe personal injury or death.
2. Remove the cover of the ePump junction box and
feed the RS-485 cable into the fitting.
3. Unplug the RS-485 connector from the ePump.
4. Attach the four (4) wires in the RS-485 cable to
the RS-485 connector. Match the wire colors with
the positions on the connector: 1- red, 2- black,
3- yellow, and 4- green. See Figure 4.
5. Insert the RS-485 connector back into the ePump.
6. Slide dip switches 1 and 2 up, so they are in the
ON position, and slide switches 3 and 4 down, so
they are in the OFF position. See Figure 4.
7. Connect the other end of the cable to the
controller. Match the colors of the wires with the
appropriate connector positions, as described in
Step 4.
8. Restore power to the ePump and verify the
operation of the controller.
9. Refer to the ePump Controller Owner’s Manual,
H0311200, to operate the pump.
