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 safeguarded a visibly safe future for marine vessels in all weather conditions.
With the 230RCB-series searchlight, DHR introduces an entry level remote controlled LED searchlight. The
75W LED engine produces a color output of 5.000K and an intensity close to the same performance levels
of 1.000W halogen searchlights. Using the best available parabolic mirror reflectors on the market, a crisp
& clear spot with no visible stray light has been ensured. The 230RCB is equipped with an unique bracket
design to realize an extreme downward vertical angle. This is specifically useful for close range targets.
Positions on high structures or foremasts of inland navigation vessels, where high angles up to 60° are
desired, the 230RCN is the answer.

1. MOUNTING INSTRUCTIONS
Mounting the panel
Place the control panel inside the wheelhouse, where it is protected against weather influences. The panel
has been designed in order to be flush-mounted in an instrument cabinet, as shown in the illustration below.
The minimum space needed behind the panel is 110 mm. (depth)
97 ± 1 mm
97 ± 1 mm
Cut-out panel
Searchlight installation
Install the searchlight in a horizontal upright position with sufficient space around the head of the searchlight
to ensure it can move freely. The dimensions can be found on page 9.

• 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.

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
• Prefered 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 firmly (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 shrink-
able cover on the cable gland to improve water tightness.
