encounter any difficulty during this operation, DO NOT USE
UNDUE FORCE. Check all components and repeat the procedure.

3. Installation

Mounting the yoke

Locate, in the packaging, the “L”-shaped yoke, the M5 bolt, the
graduated fixing plate, and the T-handle.
Assemble the yoke prior to mounting it to the housing. Slide the
threaded M8 end of the T-handle through the untapped hole of
the yoke (placing the smooth washer between yoke and T-hand-
le), and affix the graduated fixing plate so that the markings are
to the exterior, adjacent to the yoke. Open the front inspection
lid of the 

sequenza 500 al

and insert the M5 bolt in the lateral

slot on the yoke fixing side. Now slide the yoke onto the guide
located on the external side of the 

sequenza 500 al

and con-

nect and tighten the bolt to the yoke with a screwdriver. This
tightening will result in the yoke sliding along its guide and sea-
ting itself correctly. Do not use undue force in this operation.

assembling multiple units

This procedure is similar to that of mounting the yoke. Open the
front inspection lid of the 

sequenza 500 al

and insert the M5

bolt into the lateral slot on the side of one of the 

sequenza

500 al

to be joined. Slide the accessory joining piece (

coemar

cod. 5086

) onto the guide, then connect and tighten the bolt. 

This tightening will result in the joining piece sliding along the guide
and seating itself correctly. Do not use undue force in this operation.
You can now connect the 

sequenza 500 al

units together.

Safety glass

The 

sequenza 500 al

has a tempered safety glass fitted as stan-

dard. This is useful in case a lamp ruptures, averting the risk of hot,
falling glass. If necessary, it is possible to remove the safety glass by
means of removing the 4 screws which fix  the front housing.

mounting accessories

Each 

sequenza 500 al

is supplied with a colour frame which

has one serrated edge and which fits into the front housing. The
serrated edge may be place to the top or to the bottom of the
fixture, however is desired. The 

sequenza 500 al

also has avai-

lable an accessory barndoor  which fits to the front of the unit.
