Warranty & Compatibility

Installation Information

Disconnect all electrical power to the IntelliCenter automation system before servicing or replacing the circuit board.

Before removing the existing i5X board, identify and document all wiring, communication cables, expansion-card connections, and other control connections. Inspect connectors, wiring harnesses, transformers, relays, and communication wiring for corrosion, overheating, or physical damage.

Because the 523051 is an electronic automation component located inside equipment containing line-voltage circuits, installation should be performed by a qualified pool automation professional or electrician.

Confirm Before Ordering
