Exterior 400 Range user manual
Mounting fasteners
Warning! All fasteners used to mount the Exterior 400 Range must be corrosion-resistant and
strong enough to mount the fixture safely. The washers supplied with the fixture must be installed
directly under the fasteners’ heads when anchoring the yoke base to the installation surface.
The mounting yoke base must be safely anchored to a flat surface. The number and type of fasteners used
will depend on the installation, but use at least three high-strength corrosion-resistant fasteners
(recommended minimum properties: stainless steel A4-70 grade according to ISO 3506 or steel grade 8.8
according to ISO 898-1). All nuts used must be self-locking. Washers must be installed between the head of
each fastener and the yoke base.
The yoke allows the fixture to be manually panned (i.e. rotated horizontally) and tilted for beam aiming
adjustment.
See Figure 5. To mount the fixture, use a 12 mm (1/2 inch) thread diameter bolt in the center hole
A
. Then
either use two bolts with 12 mm (1/2 inch) shaft diameter passing through holes
B
or use two bolts with 8
mm (5/16 inch) shaft diameter passing through slots
C
to anchor the fixture. installing bolts through slots
C
will give approximately 90° of pan adjustment.
Install washers under all nuts and bolt heads.
If additional bolts are required to mount the fixture safely, install bolts through holes
B
and
slots
C
.
Tilt adjustment
Tilt adjustment can be carried out with the fixture powered on.
To adjust tilt:
1. Put on heat-resistant gloves if the fixture is or has
recently been powered on.
2. See Figure 6. Loosen,
but
do not remove
, the tilt
lock screws (arrowed). Tilt the fixture to the
desired angle and retighten the screws.
If it is impossible to achieve the desired tilt angle, the
longer yoke available from Martin™ may provide a
solution (see “Extended mounting yoke” on page 8).
