Custom Lumitec Kraken installations that exceed the maximum current of a single power supply (PSU)
can be extended by installing additional PSUs. Lumitec provides the following wiring principals
illustrated below as guidance.
With this method of installation, the power and color of your Kraken lights can be controlled using a
toggle switch or controlled with the Lumitec Poco Digital Lighting Controller. The Kraken underwater
dock lights are powered through the Red and Black wires and controlled through the orange data wire
as shown in Figure 1.
Figure 1: Kraken wiring diagram. Basic installation.
To use a single controller for Kraken underwater lights on multiple PSUs, the control signal orange wire
(data) and black wire (ground) must be run to each light as shown in Figure 2. Lumitec strongly advises
the use of optocouplers to isolate each PSU from the others in the system. This is recommended to
lower the risk that nearby lightning strikes and electrical surges that could damage all interconnected
systems if an isolation barrier is not provided.
Figure 2 provides information on recommended components as well as the suggested wiring
configuration. Lumitec has tested and recommends using Wago optocoupler part number 859-758 for
transmitting the digital control signal without distortion. For additional details on lightning protection
see the section in this manual titled Surge Arrestor Installations.
