Installation
Safety Requirements
• For direct wiring of underwater lights, the installation must comply with provisions of the Na-
tional Electric Code, ANSI/NFPA 70, including those in Article 680 - Swimming Pools, Fountains,
and Similar Installation, or articles 68-060, 062 and 066 of the Canadian Electric Code
• The enclosure of the transformer must be provided with a fail-proof ground as required by NEC,
Article 680 and any applicable local codes. For Canadian installations, the supply circuit must
be protected by a ground fault circuit interrupter.
• Be sure to run the branch circuit grounding conductor to the equipment grounding conductor
terminal of the panel board and that this terminal must be directly connected to the panel board
enclosure.
• Because the SmartPower Transformer is supplied with a xx foot length of communication cable
that must connect to the Omni control, find a suitable mounting location that is within reach.
The transformer should be mounted at least 1 foot above the deck level with the field wiring
compartment down and at least 4 feet (1.2m) away from the inside wall of the pool.
• Use the appropriate size waterproof fitting and duct seal to connect the conduit from the pool/
spa light to the transformer.
• All unused openings in the transformer must be closed with acceptable plugs.
• Install to permit access for servicing.
High Voltage Wiring
Unlike conventional transformers, the Smart Power Transformer requires a constant 120 VAC, 60Hz
input power from a service panel (do not use a control relay). Turning the lights on/off is controlled
by RS-485 communication from the Omni control. Use the blue and white conductors when wiring
input power. A grounding lug is also provided. Refer to the diagram below.
Note that if you are replacing an existing transformer that is wired to a relay, the wire should be
moved to the service panel to allow for a constant 120 VAC, 60Hz input power to the transformer.
