f Do not install the projector in a confined space.
When installing the projector in a confined space, provide air conditioning or ventilation separately. Exhaust heat may ac-
cumulate when the ventilation is not enough, triggering the protection circuit of the projector.
f Panasonic takes no responsibility for any damage to the product caused by an inappropriate choice of location for install-
ing the projector, even if the warranty period of the product has not expired.
Usable outlet
100 mm (3-15/16") or longer
500 mm (19-11/16") or longer
500 mm (19-11/16") or longer
500 mm (19-11/16") or longer
This projector supports AC 100 V to AC 240 V as the power supply. A grounded outlet supporting 15 A is required
with either voltage.
The shape of the usable outlet differs depending on the power supply. Following illustrations are examples.

1. Safety Precautions
1. 1. General Guidelines
- For continued safety, no modification of any circuit must be attempted.
- Unplug the power cord from the power outlet before disassembling this projector.
- Use correctly the supplied power cord and must ground it.
- It is advisable to use an isolation transformer in the AC power line before the service.
- Be careful not to touch the rotation part (cooling fan, etc.) of this projector when you service with the upper case removed
and the power supply turned ON.
- Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated or damaged by
the short circuit.
- After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combi-
nations must be properly installed.
- After the service, check the leakage current to prevent the customer from getting an electric shock.
1. 2. Leakage Current Check
1. Prepare the measuring circuit as shown in Fig.1.
Be sure to use a voltmeter having the performance described in Table 1.
2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.
3. Connect M1 to T1 according to Fig. 2 and measure the voltage.
4. Change the connection of M1 from T1 to T2 and measure the voltage again.
5. The voltmeter must read 0.375 V or lower in both of steps 3 and 4. This means that the current must be 0.75mA or less.
6. If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer
because of a possibility of an electric shock.
