Guidance and manufacturer’s declaration-electromagnetic immunity
The MBB15K2DM is intended for use in the electromagnetic environment specified below.
The customer or the user of the MBB15K2DM; should assure that it is used in such an
environment.

IEC 61000-4-2 ± 6 kV contact
± 8 kV air ± 6 kV contact
± 8 kV air Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the
relative humidity should be
at least 30%
Electrical fast

applicable Mains power quality
should be that of a typical
commercial or hospital
environment.
Surge IEC 61000-4-5 ± 1kV line(s) to
