SAFETY INSTRUCTIONS

A Word of Caution.

Please remember you will be working with 120 volts and you can suffer electric shoc k from any exposed lives
wires. So please be careful at all times and behave wisely.
Now you’re MY 250Ì
ensure a safe operation, it is absolutely essential that the installer and user follow the safety instructions and
warning notes written in this user manual. Remember any damage caused by disregarding the manual or no t
reading it, will not be covered by warranty and Elektralite (or any of its dealers) will not accept responsibility for
any resulting damage or problems.

If MY 250Ì has been exposed to large environmental temperature changes in transit please do not switch it on
immediately it is unpacked. There maybe internal condensation. So leave MY 250Ì off until it has reached the
running temperature of the venue.

Elektralite’s MY 250Ì needs to be grounded. Do NOT cut the ground pin or try to use two-core cable to
connect it to a 120-volt receptacle. To be safe and to work properly you must have this fixture grounded.

Make sure that the power is only 120 volts. This unit will be damaged if you chose to install it at any other
voltage. In an installation it is always best to check the voltage before connecting. And remember never try to
connect you’re MY 250Ì live.

Make sure that the power cable is not damaged and never break off the ground pin.

Always disconnect the power, when the device is not in use or before cleaning it. If you don’t then you are
wasting the lamp life. Merely closing the shutter just stops the light output, it doe s NOT TURN OFF THE LAMP.

Never try to disconnect you’re MY 250Ì by pulling out the plug by tugging the cord.
Never touch MY 250Ì when powered up. The lamp produces a considerable amount of heat and as a result the

housing does get hot. You can be burnt if you touch it.
Never look directly into the lamp source. Sensitive person could suffer an epileptic shock.

Never open MY 250Ì and look at the lamp when the lamp is still on or when it is turned off but still hot or even
warm. MY 250Ì uses a discharge lamp, which is volatile. The lamp can explode at anytime. Use extreme
caution and do not expose yourself to it. When replacing the lamp do not touch any glass pa rt of the lamp. Only
handle by the silver terminal ends. Do not over tighten when installing a new lamp. Hand tight is more than
enough. PLEASE make sure that power to the fixture is disconnected
room temperature before installing a new lamp.

GENERAL GUIDELINES

MY 250Ì is a lighting effect for professional use on stages, in clubs, theatres, and so on.
This fixture should only be operated at the voltage, which stated in the technical specifications in the last page
of this manual.

MY 250Ì is designed for indoor use only.
MY 250Ì is not designed for permanent operation. Consistent operation breaks may ensure that the device will

serve you for a long time without defects.
Do not shake MY 250.
Do not use physical force when installing or operating MY 250Ì.
While choosing the installation position, please make sure that MY 250Ì is not exposed to extreme heat,
moisture or dust.
The minimum distance from MY 250Ì output front lens to any illuminated surface must be more than 3 feet.
Please be careful what surface you shine the light onto; light also has heat and this can affect the illuminated
surface. Elektralite will not be responsible for fading, color distortion or heat distortion caused by the light
beam.
When you hang MY 250Ì please use an appropriate safety cable. Please make sure that any hanging
equipment, like threaded rod or C clamp is appropriate for the job. Remember, with a moving yoke fixture, that
the momentum of moving this large mass will cause extra “stress” on any mounting materials. When mounting
MY 250Ì in the air be sure to use bolts which are M10.The M10 bolts should be no less
the thread type should be 1.5mm.
Metric explanation:- If you go to a good hardware store (like Home Depot or Lowe’s) you will be purchasin g
bolts that have written on the packaging 10mm x 1.5mm x 25mm. [The last figure of 25mm can be a higher
value read on].
10mm is the diameter of the bolt itself. 10mm is roughly 0.4 of an inch. In engineering drawings 10mm is also
written or described as M10.

1.5mm is the distance between each thread or turn of the screw. Engineering drawings refer to this as the pitch
of the screw. Now in places like Home Depot they stock 10mm bolts with 1.0mm, 1.25mm and 1.5mm pit ch. So
be careful you buy the right pitch: 1.5mm.
25mm is the minimum
30mm, 35mm and so on. Choose the bolt that best fits the length you will need to hold the C clamp or whatever
clamping device you will be using.
Finally, just FYI 25.4mm is 1 inch.

Only operate MY 250Ì you know its functions. Do not permit operation by persons not qualified.
Please use the original packaging if the device is to be transported. [Beware the majority of shipping

companies will not accept any liability for damage if the fixture is not shipped in the manufacturer’s original box
and insert packaging material].

If this fixture is operated in any other way different to that described in this manual, the fixture could be
damaged and any warranty would be void.

INSTALLATION INSTRUCTIONS

A). Installing or replacing the lamp

1. Install the lamp with the fixture unplugged from the electric source.
Never try to replace a lamp with the fixture still turned on and still hooked up to the electric.

2. If you are replacing the lamp, before opening the ho using to replace it,
let it cool down to room temperature. The lamp burns at very high
temperatures and it is a discharge lamp. If the lamp has been running then
expect anything up to half an hour before the housing is cool enough to
consider even opening up.

3. When installing a new lamp do not touch any glass part of the lamp.
Always use a clean cloth to handle lamps. The sweat from your fingers will cause the lamp to
burn incorrectly and will shorten lamp life. If you do touch the glass, then check in the lamp box

3

for a special wipe to clean the lamp.

4. Only install Philips MSD 250 or MSD 250/2 GY9.5 lamp. Any other lamp is not acceptable.

Procedure:

1. Unscrew the 3 screws on the top of the housing. The lamp is underneath the plate. Carefully remove
the metal plate.

2. Then unscrew the 2 big screws and gently pull the socket holder u sing the knob in the middle.

3. Carefully insert the lamp into the socket making sure the spring clips secure the lamp socket
correctly. Then insert the plate back into the fixture and fasten the 2 screws back in place.

4. On the plate there are 3 small screws marked 1, 2 and 3. These are used to adjust the lamp. You can
adjust the 3 screws to fine-tune the position of the lamp. In this way you can achieve the maximum

output from the lamp

.

Please remember the lamp is not a hot-restrike type. You must wait for approximately 10
Minutes, after having turned off the lamp, before you can turn it back on again.

Warning- Never ever operate the lamp when it is not inside the fixture. MSD lamps are volatile and could

possible explode. Only turn on the fixture with the lamp securely inside the fixture and the cover plate screwed
on.

B). Mounting MY 250Ì.

Method 1: Installation using a C clamp.

The installation must always be secured with a backup safety attachment: namely an appropriate sized safety
cable. Don’t clamp the safety to a C clamp. That defeats the reason for a safety cable….namely a SEPARATE
backup to the primary hanging mechanism.

Never stand directly below the device when mounting, removing or servicing the MY 250Ì.
Please make sure MY 250Ì has been installed correctly both from a mechanical and electrical aspect before

powering up and operating for the first time. Spending a few extra minutes double-checking ev erything is better
than rushing to turn the fixture on.

Care should be taken to mount MY 250Ì. Make sure that MY 250Ì is mounted in such a way that no one can
touch it directly. For example, when hanging MY 250Ì make sure it is high enough up not to hit anyone’s head
or run into any obstruction in its movement. Always keep MY 250Ì away from any inflammable material.
Mounting MY 250Ì is a job that requires qualified personnel with experience. If the personnel doing the
installation lack these qualifications do not use them to do the installation.

Safety-chain

M10 X 25mm

.

Using M10 (10mm) bolts screw the C clamps onto the base of MY 250Ì make sure that the bolts are firmly
tightened but take care not to over tighten. Fit a suitable safety chain to MY 250Ì’s center hole and attach to the
truss or whatever MY 250Ì is attached to.
Metric explanation:- If you go to a good hardware store (like Home Depot or Lowe’s) you will be purchasin g
bolts that have written on the packaging 10mm x 1.5mm x 25mm. [The last figure of 25mm can be a higher
value read on].
10mm is the diameter of the bolt itself. 10mm is roughly 0.4 of an inch. In engineering drawings 10mm is also

25mm is the minimum
30mm, 35mm and so on. Choose the bolt that best fits the length you will need to hold the C clamp or whatever
clamping device you will be using.
Do not attempt to use any other bolt apart from M10 (10mm) with a 1.5mm thread. If you try to force a wrong
bolt size the threads in the holes will be ruined and rendered useless as a load bearing point. Then you’ll have
to replace the base of the fixture.

Method 2 : Installation using U Bracket Claps with half Cheeseboros/couplers.

[The U brackets and the appropriate base for the mounting these brackets are an after sales accessory.
They do not

come as standard when the fixture is purchased].

U brackets can be used as an alternative installation method. They can have either half cheeseboros or C
clamps fitted to them.
Fit the half cheeseboros or C clamps to the U brackets. Then fit the U brackets to the MY 250Ì using the
camlocs.
Finally, fit a safety chain to MY 250Ì and remember don’t clamp the safety to the same half cheeseboros or C
clamp. That defeats the reason for a safety cable….namely a SEPARATE backup to the primary hanging
mechanism.

DMX-512 control connection.

Connect the 3 pin XLR cable to the DMX controller and then to the first MY 250Ì in the daisy chain. Doing this
way round avoids the pain of rewiring, if you get the wrong end of the cable back at the controller.
Continue wiring from one MY 250Ì to another in a daisy chain manner. Never try to Y split cables. Never try to
“star wire” a DMX cable run, it will not work.
If additional cable needs to be made up then two-core cable with a screen needs to be purchased. For wiring
please see the diagram below.

DMX has a maximum running distance of 330 feet. When long distances are involved then there is a tendency
for electrical noise to be evident. In which case a DMX terminator will be required. The terminator helps prevent
corruption of the DMX signal. To make a DMX terminator simply solder a 120 ohm resistor across pins 2 and 3
of an XLR male connector. Then place that connector at the very end of the DMX cable run. In other words at
the last MY 250Ì.

It maybe the case that you will need to connect a 5 pin XLR to the 3 pin XLR. In a normal DMX wiring
configuration, the 5 pin is soldered identically to the 3 pin. So in the 5 pin

1: Ground

2: Signal (-)

3: Signal (+)

Pins 4 and 5 are not used. Be very sure you read the pin numbering on the connector when you solder up the
connector. Do not just wire up the three pins to the left or right because the male and female connector has the pins
on different “sides” of the connector! Read the pin numbers.
