POWER
The Flex is designed to operate with a universal input power supply (100/115/230VAC) at 50/60
Hz. Noise-free power of the correct voltage and frequency, with a safety earth ground, should be
available through a standard wall receptacle. The power outlet should be able to supply 15 amps
@ 100 or 115VAC ±10% or 7.5 amps @ 230VAC ±10%. These requirements can be checked by
using a circuit analyzer (available at most hardware or electronic supply houses) or a multimeter.
There should also be sufficient outlets for the analyzer, SmartVacPrep (if purchased), dry
roughing pump, computer, monitor, printer, and any other peripheral devices.
The instrument should be connected to a switch which meets relevant requirements of IEC 60947-
3 or a circuit breaker which meets the relevant requirements of IEC 60947-2.
The analyzer and peripheral devices must be installed on their own dedicated power
line. Other devices — such as motors, generators, or ovens — should not be placed
on the same power line.
Replacement power supply cords must be rated for the specifications stated above.
TEMPERATURE AND HUMIDITY
Temperature and humidity must be controlled to within:
n Temperature: 10 to 35 °C (50 to 95 °F) operating; 0 to 50 °C (32 to 122 °F) nonoperating
n Humidity:20 to 80% relative, non-condensing
Do Not:
n Allow room temperature or humidity to exceed limits.
n Install the analyzer where it is exposed to direct sunlight.
n Locate the analyzer near air conditioning or heating vents.
