Preparation of Installation using Pedestal Stand
Pedestal Stand (TY-ST103PF9)
1)The power source is to be 240V – 1550W
2)Floor strength is to be more than 500kg/m2(102.408lb/ft2). To avoid damaging the floor, prepare an
underlay board, more than 15mm (0.6”) thick and larger than the size of the bottom stand to disperse
load.
3)To prevent personal injury or damage on goods, the following measures must be taken.
* (1) Secure the Plasma by anchoring
* (2) Secure the Plasma to the wall by wires or chains. (against toppling)
* (3) (1)+(2) both
Keep the earthquake-resistance strength and right construction procedure.
4) Prepare two fixing points at the wall or building structure to prevent toppling.
(M10 anchor bolt, more than 45mm (2”) depth)
5)Prepare four fixing points for anchor bolts.
(M12 anchor bolt, more than 60mm (2.4”) depth)
6)Keep more than 300mm (11.8”) of open space from the top and both sides of the unit. Keep
more than 200mm (8”) from the rear cover of the Plasma for heat release.
7)For safety, more than 4 persons are recommended to do the work.
8)Prepare blankets or any soft fabric to prevent damaging the Plasma or the wall/floor
during this installation work.
9)The Plasma Monitor weighs 220kg (500lbs) and the Pedestal Stand 122kg (280lbs).
To perform the installation, a hanging appliance or machine (such as Chain-block) is
recommended.
10) Be careful not to tighten the bolts/screws too much or too little.
11) Perform the installation on a flat surface and follow the instruction of the manual.

Electrical Work
1)The power source for this plasma monitor is 240V-1550W.
Confirm that the source voltage is of the right level and capacity before installation.
(Electrical Work requires a licensed electrician)
2)The prepackaged power cable is 3m length.
3)Confirm the location of the power cord.
Do not allow the cable to be pinched between walls, forcedly bent, or
twisted. The wires within the cable should not be exposed or short-circuited to avoid
possible electrification and the start of a fire.
4) Separate the signal cables from the power cord.

Preparation
1)Power requirement is 240V-1550W. (refer : “Electrical Work”)
2)Keep more than 300mm of empty space from the top and both sides of the unit. Keep
more than 200mm from the rear cover of the Plasma to maintain the ambient
temperature at 40 degree C or less. Moreover, it is recommended to keep more than
700mm maintenance space at the backside.
3) Do not install the Plasma monitor in an environment that may cause troubles and
problems to its performance.
- near the sprinkler and any sensor
- where it could receive vibration and shock
- near a high voltage cable and power source
- near a source that provides magnetic field, heat, moisture, oily smoke, etc.
- where it can receive the air (exhaust) of a fan or a heater (to prevent dust accumulation)
4)Use appropriate construction methods to select the materials for the construction of the
installation structure.
5)For wall fixing, use M12 x 80mm bolt (or equivalent, commercially available) which is
appropriate to the construction materials (reinforcing steel, concrete and etc.)
