fasteners (recommended minimum properties: stainless steel A4-70 grade according to ISO 3506 or steel
grade 8.8 according to ISO 898-1). Any nuts used must be self-locking. Washers must be installed between
the head of each fastener and the yoke base. Suitable washers are supplied with the fixture.
See Figure 6. To mount the fixture:
1. Attach a safety cable that is approved for the weight of the fixture to a secure anchoring point such as an
eyebolt in the installation surface and loop it through one of the holes in the yoke base shown as
A
,
B
or
C
in Figure 6.
2. Fasten the yoke base to the mounting surface using a 12 mm (1/2 inch) shaft diameter bolt with a
washer in the center hole
A
.
3. Then either use two bolts with 12 mm (1/2 inch) shaft diameter and washers passing through holes
B
or
use two bolts with 8 mm (5/16 inch) shaft diameter and washers passing through slots
C
to secure the
fixture. Installing bolts through slots
C
will give approximately 90° of pan adjustment.
If additional bolts are required to mount the fixture safely, install bolts through holes
B and
slots
C
.
Tilt adjustment
Tilt-lock screws at either side of the mounting yoke allow adjustment of vertical beam aiming. It is possible
to slide the fixture in the yoke once the tilt-lock screws are loosened. This allows some extra clearance and
adjustment.
Important! Do not slide the fixture in the yoke so far that the yoke comes into contact with one of the silicone
seals between the aluminum elements in the housing, as this may make it impossible to achieve a
waterproof seal.
Tilt adjustment can be carried out with the fixture powered on. To adjust the tilt:
1. Put on heat-resistant gloves if the fixture is or has recently been powered on.
2. See Figure 7. Loosen, but do not remove, the tilt-lock screws.
3. Tilt the fixture to the desired angle and slide it backwards or forwards in the yoke until its weight is
evenly distributed.
