2.0 DESCRIPTION
The PT780 Legacy® Series pan/tilt units are designed for medium, indoor/outdoor
use.
Only Legacy Series enclosures can be mounted on the pan/tilt units. These enclosures are the EH4700L and EH5700L environmental enclosures and the EH8106L
pressurized enclosure. Pelco’s RediLINKTM connector makes it simple and quick
for you to install an enclosure. The weight of the enclosure with camera and lens
must not exceed 40 pounds (18.14 kg) with the 12 VDC pan/tilt units or 52 pounds
(23.56 kg) with the 24 VAC or 120 VAC pan/tilt units.
You can easily remove the clamshell covers from the sides of the pan/tilt units to
access all internal parts without having to remove the camera enclosure. This makes
it easy to service the units and to adjust the pan and tilt limit stops.

3.1 MOUNTING
3.0 INSTALLATION
NOTE:
To insure proper wiring and
operation of your equipment, it is recommended that you test the pan/tilt
unit and associated equipment in your
facility before installing it in the field.
Refer to Sections 3.2 through 3.4.
CAUTION:
The PT780
pan/tilt units are designed
for upright or inverted (base
up) operation. Never mount
the pan/tilt horizontally.
NOTE:
If you mount your pan/tilt unit
in the inverted position, you must install a rain cover (part number
90010018).
Attach the pan/tilt unit to a wall or ceiling mount. Follow the instructions that are
provided with the mount. Make sure the mounting surface and the selected mount
can support four times the combined weight of the pan/tilt unit and the camera
enclosure (including the camera and lens). The pan/tilt unit weighs approximately
21.5 pounds (9.68 kg). Refer to the manuals for your enclosure, camera, and lens
for the weights of those items.
