BOWA-IFU-11779-ARC400-V2.1.0-S0-EN Operating Manual ARC 400 161
Immunity to electromagnetic interference (IEC 60601-1-2, Table 2)
The ARC 400 is intended for operation in an electromagnetic environment as described below. The customer or
user of the ARC 400 should ensure that it is operated in such an environment.
Interference immunity

Electromagnetic
environment guidelines
Electrostatic discharge
(ESD) according to
IEC 61000-4-2
Floors should be wooden
or concrete or finished with
ceramic tiles. If the floor is
finished with a synthetic
material, the relative
humidity must be at least
30%.
Fast transient electrical
noise or bursts according
to IEC 61000-4-4
The quality of the AC
power should correspond
to that of a typical business
or hospital environment.
±1 kV on input and output
lines
±1 kV on input and output
lines
Surges according to
IEC 61000-4-5
±1 kV between external
conductors
±1 kV between external
conductors
The quality of the AC
power should correspond
to that of a typical business
or hospital environment.
±2 kV between external
conductor and ground
±2 kV between external
conductor and ground

The quality of the AC
power should correspond
to that of a typical business
or hospital environment. If
the ARC 400 user requires
it to continue operating in
the event of a power
dropout, it is recommended
to power the ARC 400 from
an uninterruptible power
supply or a battery.
Note: U
T
is the AC supply voltage before the test level is applied.
