The quality of the power
supply should correspond to
that of a typical commercial or
hospital environment. If the
user of the HICO-Variotherm
550 demands a continued
operation during interruptions
of the power supply, we
recommend to supply the
HICO-Variotherm 550 from an
uninterruptible power supply or
a battery.

field according to
IEC 61000-4-8
3 A/m
3 A/m
Magnetic fields at the mains
frequency should correspond
to that of a typical commercial
and hospital environment
