2 Safety
Be sure to observe the following safety instructions. Failure to do so will pose a danger to
yourself and others.
2.1 General information
Intended use
The searchlights the SX 450 Series are designed to shine a spotlight on distant objects. The
searchlights have a range between 6700 m and 9600 m, depending on the type of unit.
The searchlights are designed for use on ships, in particular for polar voyages through icy
waters.
Due to its high intensity, the searchlight is not to be used to illuminate persons near the
searchlight.
It is not designed for lighting rooms on the ship or in buildings.
Danger! The searchlight should not be altered or modified in any way due to
the danger this to persons and damage which may occur to the searchlight.
Failure to observe this will void the approval certificate.
Only original spare parts may be used.
The use of unauthorized spare parts will void any warranty.
Danger of burns! Never touch the searchlight during operation. The housing
may reach temperatures as high as 150 °C. Always allow the searchlight to
cool down before carrying out maintenance work or repairs. In case of burns,
immediately cool the burned area and get medical help.
Danger of blinding! Never look into the source of light during operation. This
poses a danger to your eyesight. Never point the searchlight at people.
Danger of crushing! Danger of cutting! Be sure that there are no persons
directly next to the searchlight before rotating or tilting the searchlight. Persons
standing near the searchlight may get limbs caught between the searchlight
and base, and serious injuries may result.
2.2 Working with Xenon lamps
Danger of explosion! Xenon lamps are under high pressure even if not in
use (20 bar). During operation, the pressure may rise to as much as 70 bar.
For this reason, the following safety precautions must be observed when
working with Xenon lamps:
Transport
•Always store and transport xenon lamps in their protective shroud.
•Keep the protective shroud in a safe place after installing the lamp.
•Place xenon lamps back in their protective shroud immediately after taking
them out of the searchlight.

Safety
Instruction Manual WISKA Edition 1.6 –09/2020 4
Article-No.: 30078457001
Required protective clothing
Never open the searchlight when not wearing appropriate protective clothing. Always wear
protective clothing while near to an uncovered xenon lamp or while moving a xenon lamp without
its protective shroud.
The required protective clothing consists of:
- Safety goggles to protect eyes
- Face mask with throat protection
- Safety gloves with wrist protection
Operating the lamp
•Never touch the bare lamp bulb with your bare hands. Before screwing
in the lamp, remove any fingerprint smudges using a non-abrasive, lint-
free cloth and alcohol solution.
•Check the lamp for any scratches, cracks, or other signs of damage. Do
not use damaged lamps.
•Be sure to observe the correct polarity. Installing the lamp with the wrong
polarity renders the lamp useless.
Service life
Xenon lamps have an average life of about 1,500 operating hours. Replace the lamps at the
latest when this level of service life has been reached.
Disposal
Xenon lamps must be fractured to depressurise them before
disposal.
Danger of explosion! Depressurise the lamp bulbs in a suitably safe place. Be sure
that there are no other people in the immediate vicinity.
Wear protective eyewear and clothing!
2.3 Protective measures
Temperature
- The installed xenon lamp becomes very hot during operation. A
thermostat controlled blower circulates air in the housing to reduce the
temperature by conducting heat to the outside.
- To avoid moisture accumulation and facilitate ignition, a minimum
temperature of 6 °C inside the lamp housing is required. To ensure that
the minimum temperature is maintained, the searchlight housing is
equipped with a thermostat- controlled heater. The heater also protects
the searchlight from freezing.
- The optional FL52 pan and tilt unit can additionally be equipped with an
optional thermostat-controlled heating unit (Option: ICE-version).
Attention! To ensure that the minimum temperature is maintained during cold
weather conditions:
•Keep the searchlight ready for operation by leaving the main switch S8
in ON condition. Turn on the searchlight only through the switch S1,

Safety
Instruction Manual WISKA Edition 1.6 –09/2020 5
Article-No.: 30078457001
which may be located on the control unit or may exist as a separate
switch.
•Do not turn on the searchlight immediately if power has been cut off for
a prolonged period of time while the temperatures were at 6 °C or less.
First, place the searchlight in standby mode by switch S8 and wait until
the minimal internal operating temperature has been reached inside the
housing.
Radiation/ Emission of dangerous particles
•Xenon lamps emit UV light, which is hazardous to your eyes. The special
design of the searchlight prevents direct eye contact with the arc
searchlight.
-If a Xenon lamp should explode during operation, the robust housing will
stay intact and prevent hot glass shards from being expelled.
2.4 Operating requirements
Protection Class
The searchlight, power supply unit and the optional drive unit have an IP 56 protection class
rating (dust-protected, heavy seas and powerful water jets). All electrical cables may only be
inserted through appropriate cable glands to maintain this protection class.
Requirement for placement
Where to install
- the searchlight: under normal operating conditions, the housing of the
searchlight will reach temperatures up to 150 °C. Mount the searchlight
only in an environment that can resist this heat. To rule out all potential
dangers: do not store any explosive or easily inflammable materials in
the immediate area of the searchlight. Such materials include gasoline,
paper and paint.
- The power supply unit PSUX: Install the PSUX at a cool place which is
not exposed to direct sunlight, vented hot air or other dissipated heat from
fuel tanks
Attention! The searchlight and power supply unit PSUX are operating under
high voltage. To prevent electromagnetic interference with the compass, make
sure an appropriate distance is maintained between the searchlight, the power
supply unit PSUX and the compass. Also, do not run cables in the direct
proximity of the compass.
2.5 Maintenance / cleaning
Before carrying out maintenance or cleaning work:
•Turn off the main switch.
•Make sure the entire electrical system is dead.
•Wait until the searchlight has cooled down.
•Wear protective clothing when opening the searchlight.

Technical specifications
There are four types of SX450 Searchlights, which differ from each other,
basically by the performance of its Xenon lamp. The two types of lamps
are 1000 W and 2000 W. The following table will show the technical details
of each type in individual columns.
To differentiate between the four types, you may consult the nameplate of
your searchlight.
