Den Haan Rotterdam
Den Haan Rotterdam is a family-owned company established in 1922. Started as a small tinsmith, it has evolved
into a globally respected producer of navigation lights, searchlights, air horns and a wide range of nautical
lamps made from copper and brass. By introducing products with advanced LED-technology, DHR has safe-
guarded a visibly safe future for marine vessels in all weather conditions.
Den Haan Rotterdam manufactures halogen searchlights for over 30 years and are known for their robustness,
quality and reliability: key values for marine equipment. The RC-series is the second generation of DHR remote
controlled type of searchlights introduced in 2019. This product range is very popular, because of its compact
size and its simplicity in installation and operation. The RC-series includes two types of light sources, such as:
halogen bulbs and LEDs. Also the optical performance is top-notch, thanks to the use of silver plated mirror
reectors.
The application of the 230-, 320- and 420-series searchlights is limitless. Mostly they are benicial for work
boats, tugs, shing vessels, dredgers and even watch towers for land based solutions.

1. MOUNTING INSTRUCTIONS
MOUNTING THE PANEL
Place the control panel inside the wheelhouse, where it is protected against weather inuences. The housing is
especially constructed to be ush mounted in an instrument cabinet according the illustration on the right.
The minimum required depth for the panel inside the console is 50 mm [4.33 inch].
SEARCHLIGHT INSTALLATION
Install the searchlight in a horizontal upright position with sucient space around the head of the searchlight to
ensure it can move freely. The dimensions can be found on page 9.
FASTENERS
• The permissible torque should be 8 Nm
• Use only A4-grade stainless steel
CAUTION!
Even though the housing is made of corrosion resistant materials, galvanic corrosion may still occur. To
prevent galvanic corrosion use the supplied insulation sleeves to isolate the aluminium housing from other
metal parts.
Den Haan Rotterdam does not accept responsibility for any damage if the searchlight is installed
incorrectly and/or used improperly. When in doubt consult a qualied electrical technician.

WARNING!

ELECTRICAL INSTALLATION
Install the electrical wiring according to the wiring diagrams showed on pages 11 - 14. Keep the distance between
the power supply and halogen lamp as short as possible. Long wires will increase a voltage drop near the halogen
lamp, which affects the light output.
CABLE GLANDS
ØD
CABLE
• Preferred diameter D is 7 - 12 mm
• Material: Neoprene H07RN-F
Cable too tight!
This gives unwanted stress at the sealing of the
cable gland and water ingress will occur.
Include cable slack at the entering
point of the cable gland
REPLACING CABLE GLAND
• Use gasket between housing
and cable gland
• Tighten rmly (6Nm) with
wrench
Remove the plug before placing the cable.
If no cable is connected, leave the plug in place!
NOTE
The cable glands on the searchlight prevent water ingress. Do not use (electrical) tape to cover the cable
where it enters the cable gland as this will cause water ingress. Do not use a rubber or shrinkable cover
on the cable gland to improve water tightness.

6. SAFETY, MAINTENANCE AND CORRECT USE
ESD
This product, like all LED searchlights, uses semi-conductors that can be damaged by elec-
trostatic discharge (ESD). When handling, take close care before opening the drum to avoid
damaging the LEDs.
THE FOLLOWING PRECAUTIONS MUST BE TAKEN:
• Always disconnect the power from the light before any maintenance.
• Use a conductive wrist strap attached to a good earth ground.
• Always discharge yourself by touching grounded bare metal.
• Use an approved anti-static mat to cover your work surface.
• When in doubt always consult a qualied electrician.
DON’T STARE DIRECTLY INTO THE LEDS.
All cool white LEDs (5000 Kelvin and higher) contain a lot of blue and can be harmful to our eyes. Always use eye
protection when handling LEDs
TIPS FOR CORRECT USE
• Switch off the searchlight immediately after use, this increases the life expectancy of the COB - LED
• Do not light-up objects closer than 2 metres
• Do not point the light beam at the eyes of humans or animals
PREVENTIVE MAINTENANCE
Clean the searchlight with fresh water regularly. Do not use any aggressive cleaning agents. At least twice a year
rub the V-ring and dirt wiper in with silicone grease.
