Connect AC power to the Power Center:
6. Use 12-14 AWG three conductor insulated wire for the main AC power connection. Connect the
Power Center to pool pump AC power source. The Power Center should be connected to the pump
motor switch or automatic timer. For system wiring information, see page 6.
7. Attach incoming GROUND wire to the ground lug inside the Power Center.
8.
Earth Bonding (Grounding)
: Connect the earth wire to the GROUND BONDING LUG located on
the bottom of the Power Center enclosure. Earth bonding is necessary to ensure personal safety and
safety of equipment.
IMPORTANT:
A number 8-gauge (8.4 mm) wire is recommended when connecting the power supply to a
Permanent Earth Ground connection that is acceptable to the local inspection authority. Attach the
bonding point located on bottom of the Power Center to a Common Earth Bonding Point. Do not use the
IntelliChlor as the Common Bonding Point. Each piece of non-chlorinator pool equipment requiring a
ground should be bonded to the Common Approved Earth Bonding Point. Never ground pool pump to
Power Center.
9. Reinstall the Power Center cover and secure with the cover screw.
10. The Power Center installation is complete. For IntelliChlor operating information, refer to the
IntelliChlor User’s Guide (P/N 520589).
