  Pan/tilts in

the PT180 Series are de-
signed for upright or in-
ver ted operation and
should never be mounted
horizontally.

Pan/tilts in the PT180 Series are designed to mount onto a horizontal surface in the
upright or inverted position.

In order to ensure proper wiring and system operation of all components, it is highly
recommended that the pan/tilt and the associated control equipment is tested in
your facility before field installation. Refer to Sections 3.3 and 3.4.

Attach the pan/tilt unit to a mount, following the instructions that accompany the
mount. To ensure maximum pan travel, mount the pan/tilt so that the fixed limit stop
is directly opposite the center of the intended viewing area.

Make sure the mounting surface and the mounting method is strong enough to sup-
port four times the combined weight of the pan/tilt, enclosure, camera and lens.

Attach the enclosure, camera and lens to the pan/tilt unit with 1/4-20 hardware (not
supplied). The enclosure, camera and lens must be correctly mounted and balanced
on the tilt table for proper operation.

Cable distances for pan and tilt motors should not exceed the distances specified
in Table A. Cable fabrication must be in accordance with Section 3.3.1, Mating
Connector Assembly. The following are some recommended common installa-
tion practices.

1.

Always use jacketed stranded multi-conductor interconnecting cable between
the control and the pan/tilt unit, with additional conductors than needed for
future servicing and or additions.

2.

Always use color-coded conductors for ease of wiring and to identify functions
at a later date.

3.

Keep a wiring diagram with the system for later use and reference.
