Installation manual
2 PRE-INSTALLATION REQUIREMENTS
2.1 Environmental requirements
Wall construction
The wall construction must be able to resist a shear load of 75 kg (170 pounds) and withdrawal force
of 200 kg (445 pounds) at each of the four attachment locations. Otherwise, some additional mount-
ing supports must be used to fulfill this requirement.
Temperature & humidity
The operating temperature range is from +15°C to +35°C, non condensing. The acceptable humidity
range is from 25% to 75%. The storage temperature range is from -5°C to +60°C.
NOTE If the X-ray unit has been stored at temperatures below +10°C for more
than a few hours, time must be allowed for the X-ray unit to reach the room
temperature before connecting it to the mains voltage.
2.2 Electrical requirements
Mains voltage
The Planmeca Intra X-ray unit has been preset at the factory to one of the 3 different mains voltage
settings. Please check that the rating indicated on the type shield and the mains voltage selector on
the generator PCB (connector P4) corresponds to the local mains voltage. The possible voltage set-
tings are:
• 100V~ (90V~...110V~)
• 110-115V~ (99V~...126V~)
• 220-240V~ (198V~...264V~)
NOTE Please note that the ratings of the internal (as well as external) mains
fuses are depending on the mains voltage setting.
CAUTION
Never connect the X-ray unit to the mains without first checking the
voltage setting. Incorrect voltage setting can cause damage to the X-ray
electronics.
Mains frequency
The mains frequency is 50 or 60 Hz, and is independent on the mains voltage setting.
