2 - Safety Precautions
The following instructions must be adhered to, in order to ensure a safe working environment
and the safety of the user.
Note: When unpacking or manoeuvring the searchlight into its fixing position, the lifting
handles must be used in order to prevent damage to the equipment or personal injury.
Because of the high internal pressure within the lamp, there is a risk of explosion in either a
hot or cold state;
During operation this lamp emits intense UV radiation which is harmful to the eyes and
skin. Suitable protection should be worn;
The high luminance of the arc can cause severe damage to the eye if viewed directly.
ALWAYS wear suitable protective goggles when viewing the lamp;
Always use protective jackets supplied with the lamp;
Should it be necessary to examine the lamp with the front bezel removed, always use a
protective shield and wear goggles to ensure a safe working environment;
Searchlights get hot. Never touch the unit when lit and always allow 15 to 20 minutes for
cooling down after turning the searchlight off;
Never place anything on or cover the searchlight when in use;
Ensure the lamp has cooled sufficiently before removal;
If undue force appears necessary to remove the lamp, the equipment should be inspected
by a competent person or contact the manufacturer;
When disposing of lamps there are several options available:
Return the lamp, via the supplier, to the lamp manufacturer in its complete
packaging
Because of the cold internal pressure of the lamp is approximately 8 bar,
the lamp must first be depressurised before disposal. Place the lamp, in its
protective jacket, in a plastic bag and drop from a height of 1 to 2 metres
onto a hard surface;
XBO lamps do not contain materials which are harmful to the environment and thus are not
subject to special waste disposal regulations;
Due to the vast range of lamps available it may appear possible that more powerful lamps
can be used in the equipment than for which it was designed. Even when the unit will
physically accept a higher wattage lamp, this substitution is not recommended and is
dangerous. This action will also void any warranties on the equipment.
Always refer to the lamp manufacturer’s technical data when dealing with lamps.

4 - Unpacking and Installation Instructions
The following instructions should be read and fully understood prior to installing the equipment
to ensure that the correct procedures are followed and all safety precautions are observed.
Note: If the equipment has been in storage for a considerable amount of time, it is
advisable to conduct a routine maintenance check on all parts before installation.
Safety Precautions
This equipment should not be connected to an electrical supply before being installed.
Installation procedures should be adhered to in order to ensure a safe working environment
and reduce the risk of damage or personal injury.
Preparing the Mounting Position
Mark out and drill the fixing holes through the deck. Fit the ‘O’ ring in position and bolt the
searchlight base securely. On an uneven surface it is necessary to use a suitable sealant, such
as silicone, in order to ensure a weatherproofed joint. If anti-vibration mounts are to be fitted,
the fixing holes for the mounts should also be marked out and drilled. Prior to manoeuvring the
searchlight into its’ fixing position, the AV mounts should be fitted to the base. When in the
desired position, bolt the searchlight firmly down.

5 - Electrical Installation
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
In order to obtain the maximum light output from the searchlight, it is essential that the full
operating voltage of the lamp fitted be applied to the lampholder contacts.
Method of Electrical Connection
1) Disconnect the supply before working on the electrical system;
2) The searchlight must be connected to a fused electrical supply, using suitably sized cable.
3) If the searchlight is located a considerable distance from the supply, provision must be
made in the cable size in order to overcome the voltage drop.
The PSU should NOT be positioned no more then 5 meters away from the searchlight.
The following table below indicates the maximum length of cable to be used for the AC
supply cable, from the control panel to the searchlight:

4) Whenever possible cable terminations should be made below deck and with approved
terminal devices;
5) If a spare auxiliary fuse or circuit breaker is not available, one of the correct type and rating
should be fitted and connected to a positive supply. It is advisable to locate a bus bar or
main connection and avoid any direct connection to the supply;
6) For 110/220v AC products, the following colour coding system should be used for the
customer supply cable:
Brown - Live
Blue - Negative
Green/Yellow - Earth
Note: This equipment must be earthed.

Installation Guidelines
A typical installation and connection routine for the searchlights is as follows:
Referring to wiring diagram X4737, a 240v or 115v AC supply should be connected to the
Power Supply Unit as shown, which then provides a common feed to all other functions and
equipment.
Cables required to be connected by the customer: -
4 core 4mm cable from the Searchlight into the PSU, doubling up the pairs.
4 core 1.5mm cable from the Searchlight to the PSU.
Mains supply cable.
(Customer may need to provide a suitable junction box to extend these cables –3 metres
supplied). The searchlight head is pre-wired.
When the light is in operation the output from the PSU should be approximately 19v dc at
54amps.
Upon striking, the running wattage of the lamp can be calculated by using the equation:
P = VI
Where P= Power (watts)
V= Voltage (V)
I = Current (Amps)
Instruments required: D.C. Ammeter & Multi meter
Procedure
1) With the multi meter, test the DC voltage in the searchlight head. This should be
approximately 19 volts.
2) With the D.C ammeter, test the current of the red DC cable at front of searchlight. It should
read approximately 54 amps.
3) Multiply these readings together, as shown above, to obtain the desired wattage required,
usually about 1026watts.
