1.2 Important safety instructions
To prevent the risk of electrical shock
• This projector should be operated from an A C power source. Ensure that the m ains voltage and capacity matches the projector
electrical ratings. If you are una ble to install the AC requirements, contact your electrician. Do not defeat the purp ose of the
grounding.
• Installation according to the local electrical code and regulations by qualified technical personnel o nly.
• This product is equipped with a three-terminal b arrier strip for the connection of a mono phase power line with a separate
earth gro und P E. If you are unable to install the AC Requirements, contact your electrician. Do not defeat the purpose of the
grounding.
• The cross-sectional area of the conductors in the power supply cord shall be not less than 4 mm
2
or AWG 10.
The cross-sectional area of the UPS inlet cord and external fan power cord shall be not less than 0.75 m m ² o r AWG 18.
• The electronics of the projector (UPS INLET ) must be powered either from a suitable UPS u nit or from the pow er outlet socket
(UPS OUT LET ) pro vided on the projector. An adapted short power c ord (2-pole 3-w ire grounding) is added to the projector
accessories to loop through the power from UP S OUTLET to UPS INLET.
• The provided power output socket (UPS OUTLE T) on the projector may o nly be used to provide power to the p
rojector elec-
tronics. Nev er connect other devices to this power output s ocket.
• The exhaust fan outlet m ay only be used to power an external blower, m axim um 3A .
• The building installation has to be provided with a circuit breaker of max. 40A to protect the comp lete unit.
• A readily accessible disconnect device must be incorporated externally to the equipmen t for rem oval of the power to the pr o-
jector mains terminals.
• Disconnect the p ower to the projector m ains terminals and unplug the power cord
at UPS INLE T for removal of all pow er from
the projector.
• Warning: High leakage c urrent. Earth connection essential before connecting supply.
• Do not allow anything to rest on the power cord. Do not locate this pr ojector where persons will walk on the cord.
• Do no t op erate the projector with a damaged cord or if the projector has been dropped or damaged - until it has been exam ined
and approved for operation by a qualified service technician.
• Position the cord so that it will not be tripped over, pulled, or contact hot surface
s.
• If an extension cord is nec essary, a cord with a current rating at least equal to that of the projector should be used . A cord rated
for less amperage than the projector may overh eat.
• Never pus h objects of any kind into this projector through cabinet slots as they m ay touch dangerous voltage points or short
circuit parts that could result in a risk of fire or electrical shoc k.
• Do n ot expose this projector to rain or mois ture.
• Do not immerse or expose this projector in w ater or other liquids.
• Do not spill liquid of any kind on this projector.
• Should any liquid or solid object fall into the c abinet, unplug the set and hav e it chec ked by qualified s ervice personnel before
resuming operations.
