Underwater light Installation
Note: Pilings should be cleaned to remove hard growth that would prevent the light for having a stable
base to install against.
Note: Stainless Steel clamps are 60 inches long and should provide enough length to wrap around a 12
inch square or 14 inch round piling.
Note: It is helpful in tidal locations that this part of the installation be performed close to low tide.
1. Slide 1 stainless steel clamp through slot in the back of the light housing. Wrap clamp around piling
and feed free end of clamp back through clamp latch and back through slot in light housing.
2. Adjust so that light is approximately 6 inches below water line at a typical low tide for your area.
3. Tension clamp by holding light with one hand and pulling cable with the other. It may help to pull the
free end of the clamp with pliers.
4. Use a second stainless steel clamp or other if needed to secure power cable to piling. Prevent
abrasion by routing cable to side of piling away from vessel access.
Power Unit Installation
Note: This fixture is suitable for installation in wet locations.
1. Determine the mounting location of the Power Unit ensuring all underwater light cables reach the
supply and are routed to prevent abrasion from vessels or other moving components.
2. Attach the power unit to suitable structure at least 1 foot above ground level with the high and low
voltage cables pointing down. The metal plate on the back of the power unit enclosure MUST be offset a
minimum of 0.28” (7mm) for proper air-flow. NOTE: Do not energize transformer until installation of
system is complete

Surge Arrestor Installation for Outdoor AC Installations
A surge protection device (SPD) has been installed in your Kraken system. Warranty claims may be
denied if an SPD has not been installed according to the recommendations in this document. Damaging
voltage fluctuations can occur from other equipment attached to the AC supply or due to induced
voltages from direct and indirect lightning strikes. Indirect lightning strikes can be especially problematic
because the voltage will be induced even at long distances from the strike location and is typically a
function of the wire length. Outdoor lighting projects typically have longer wiring and tend to be
subjected to higher induced voltages, which increases the need for SPD installation.
To prevent lightning damage to your equipment, Lumitec recommends installing a supplemental
grounding system to the one found at the service point. The grounding system directs lightning-induced
electrical current into the earth rather than allowing the surge to pass through power wires or field
wires to your equipment. The Kraken enclosure comes with a ground lug external to the enclosure.
Ground Lug

Revision C 04/2020 8
A good grounding system should maintain a resistance of 10 ohms or less to ground. Ground resistance
occurs when grounding system components, or the soil itself, oppose the flow of electricity into the
earth. The higher the ground resistance (higher ohm readings), the higher the chance the surge will
damage the equipment’s electronic components rather than be shunted to ground. If you are unable to
reach a resistance of 10 ohms or less, you can enhance the ground network with additional ground
electrodes or plates.
All grounding rods or plates must be connected with #6 AWG or larger solid copper wire. Install the
connecting wire in as straight a line as possible. If you must make a turn or bend in the wire, make the
turn in a sweeping curve with a minimum radius of 8 inches. Ground rod corrosion will increase the
ground resistance and decrease the effectiveness of the SPD. Use the correct material for your
installation environment. Copper plated, solid copper, and stainless-steel ground rods are options to
consider. Do not use galvanized grounding rods for this application.
Kraken Dock Lighting Instructions for Custom Installs
Installation with 1 controller and multiple power supplies

Revision C 04/2020 9
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.

Revision C 04/2020 10
Custom Enclosure Recommendations
Lumitec recommends installing the AC to DC power supply (PSU) within an enclosure that provides heat
dissipation. If a plastic enclosure is used, and no means for air circulation is provided, then the power
supply may go into a fault state and stop supplying power to the load until the temperature drops down
to a safe level. Typical AC to DC switching supplies are approximately 94% efficient, and 6% of the
energy is wasted as heat. As an example, a 480-Watt supply can create 29 Watts of heat when fully
loaded.
If metal enclosures are used, follow applicable NEC requirements for the grounding of dead metal.
Challenges can also occur when using metal enclosures with the Poco Digital Lighting Control unit. Be
aware that metal enclosures are not compatible with WIFI or Bluetooth connectivity.
MAINTENANCE
● The lens should be cleaned monthly to ensure continued lighting performance. To clean, brush the
lens with a stiff plastic bristled brush. Do not use a scraper, abrasive, strong alkaline, or acid cleaner.
Damage may result.
● Visually check for undue heating evidenced by discoloration of wires or other components, damaged
parts, or leakage evidenced by water or corrosion in the interior, Some small amount of water is allowed
on the interior of the power supply. Replace all worn, damaged, or malfunctioning components and
clean before putting the luminaire back into service.
● Electrically check to make sure that all connections are clean and tight.
● Mechanically check that all parts are properly assembled.
