INSTALLING CONDUIT
NOTE:
Electrical conduit and adapters are not supplied with the controller but may
be required for installation in your area. Check local electrical codes and install conduit
according to requirements.
1. For power wires, remove the terminal strip cover located below the transformer. Install
a conduit from the circuit breaker panel to the controller cabinet using the 1/2"
(13 mm) thru-hole or 3/4" (19 mm) conduit knockout.
2. For fi eld wiring, either 2" (51 mm) or 3" (75 mm) conduit can be installed. If 3" (75
mm) is required, remove the knockout ring provided to increase the hole size. Suffi cient
space is provided to enable either a hex nut or star nut to be installed on the conduit
fi tting.
CONNECTING THE POWER WIRES
WARNING:
electrical codes including installation by qualifi ed personnel. These codes may require a
means in the fi xed wiring of disconnecting AC power having a contact separation of at
least 0.120" (1/8" or 3mm) in the line and neutral poles. Ensure the AC power source is
OFF prior to connecting to the controller. The wire used for connection to the controller
must have insulation rated at 105°C minimum.
Caution:
Do not connect the controller to one phase of a three-phase power supply
used by a pump or other electrical equipment.
1. Ensure the power is disconnected at the source. See Warning above.
2. Route the AC power and equipment ground wires through electrical conduit to the
controller.
Caution:
Do not connect the controller to one phase of a three-phase power supply
used by a pump or other electrical equipment.
3. Remove the cover plate installed directly below the transformer. Use a small fl at blade
screwdriver to secure the wires.
For 120 V a.c. models, secure the wires as
follows: Line (black wire) to "L", Neutral (white
wire) to "N" and Equipment Ground (green) to
"
". See Figure 7.
For 230–240 V a.c. models, secure wires as
follows: Line (brown) to "L", Neutral (blue) to
"N" and Equipment Ground (green) to "
Reinstall the cover plate.
4. Apply power to the controller.
