Chassis Assembly

WARNING: The chassis weighs 65 lb (29.5 kg). Two people are required to handle and position the display safely.

Unpack the PMCD750 unit. The screen is not needed yet and should be left in its container at this time.

SINGLE DISPLAY

Attach the screen support to the front edge of the chassis with the supplied screen support bolts. The screen support mounts only one way.
It incorporates a stop (rest) for the screen. Refer to Figure 1.

WALL DISPLAY – FIRST ROW

Straightness of the PMCD750 display is critical because the screens have no mullion (outside screen border). If the first row in a wall
configuration is not horizontally straight, the problem will worsen as construction progresses.

To build the first row of a wall:

1. Set the first row of PMCD750 units side by side without the screens. Bolt them loosely together through the bottom connection points with
the 1/4-20 x 3.5-inch bolts, washers, and wing nuts. Refer to Figure 1.

2. Attach the screen supports to the front edge of each chassis. Refer to Figure 1.

3. Check the first row for horizontal straightness by making sure the front and top edges of adjacent units are flush. If necessary, use shims
under the units to make sure the top edges of adjacent units are flush.

4. When the first row is straight horizontally and vertically, tighten the bolts holding the units together.

WALL DISPLAY – SECOND ROW AND UP

DANGER: Because the PMCD750 unit has a narrow front-to-back profile, the danger of tipping exists with high walls. For walls over two

units high and all tilted walls, use the four tie-back points (1/4-20 threaded holes) on the rear of the unit to secure the video wall to a
structural part of the building. If the wall is tilted forward, tie the wall all the way up. Do this as the wall is being built up; do not wait until
the wall is finished. Pelco does not provide any special brackets to secure the PMCD750 unit. The method to use is best determined on site
due to the many variables to consider, and must be capable of sustaining five times the weight of each PMCD750 unit – a total of
340 pounds (154 kilograms) per unit.

WARNING: The maximum stack height for a wall is four units.

1. Stack another row of PMCD750 units on the first row. As you stack, be careful inserting the alignment pins on the second row chassis into
the alignment holes on the lower unit. Refer to Figure 3.
