ENVIRONMENT:
GUIDANCE
Floors should be wood,
concrete, or ceramic tile.
If floors are covered with
synthetic material, the
relative humidity should
be at least 30%.
Mains power quality
should be that of a typical
commercial or hospital
lines environment.
Mains power quality
mode should be that of a typical
commercial or hospital
mode environment.
Mains power quality
should be that of a typical
commercial or hospital
environment. If the user
of SERFAS Energy
Systemrequires
continued operation
during power mains
interruptions, it is
recommended that
SERFAS Energy
Systembe powered from
an uninterruptible power
supply or a battery.
Power-frequency
N/A magnetic fields should be
at levels characteristic of
a typical location in a
typical commercial or
hospital environment.
