attaching a plug

Ensure that the plug you use is rated at a minimum of 5 Amps,
with a suitable earth. It is absolutely necessary that the fixture be
correctly earthed via the yellow/green earth wire. Connect the
brown wire to the active, the blue wire to the neutral and the
yellow/green wire to earth. Make sure all wires are securely atta-
ched.
A good earth connection is vital for proper functioning of the fix-
ture. Strict adherance to regulatory standards is strongly recom-
mended.

testing

Before mounting the unit in a permanent position, connect it to
a fused outlet and test it for correct operation of the lamp.

protection

The use of a fuse rated at 2 A for a 300w lamp and 4 A for a
500w lamp, or the use of a thermal/magnetic circuit breaker for
each 

sequenza 500 al

, is highly recommended.

Should the 

sequenza 500 al

be operated via a dimming

system, ensure that the dimmer is fitted with fused load protec-
tion.

5. Operation

focusing

Whilst focusing the unit, it is recommended that any colour gel
be removed, and the lamp be dimmed so as to avoid the unit
becoming hot and therefore difficult to manoeuvre.

colour frame

Every 

sequenza 500 al

is supplied with a colour frame to suit

gel of dimensions: 250mm x 295mm. We recommend the use of
high-temperatue gel, often known as supergel.

note:

sequenza 500 al

is able to operate at any standard mains volta-

ge or frequency. A suitable lamp is the only requirement.
