Safety Considerations
Environmental Conditions for Normal Use
Indoor use only
No maximum altitude
Temperature range of -20 to 50 °C (-4 to 122 °F)
Maximum relative humidity of less than 95% (non-condensing)
Mains supply voltage range of 95-250 Vac, 50/60Hz single phase,
250W
Maximum transient voltage of 1500 Vac
Installation Category II (Overvoltage Category as defined by IEC
1010-1)
Pollution Degree 2 (as defined by IEC 664): Normally only
nonconductive pollution occurs. Temporary conductivity caused by
condensation is to be expected.
