guidelines
Floors should be made from wood
± 6 kV contact or concrete, or covered with ce-
discharge ramic tiles. If the floor is comprised
± 8 kV air discharge of synthetic materials, the relative
humidity must be at least 30 %.
± 2 kV for mains The quality of supply voltage
supply should correspond to that of a
± 1 kV for input typical commercial or hospital
and output supply environment.
± 1 kV The quality of supply voltage
Push-pull voltage should correspond to that of a
± 2 kV typical commercial or hospital
Push-push voltage environment.
The quality of supply voltage
should correspond to that of a

occurrence of a disruption in
energy supply, it is recommended
0 % U for 5 s
T
that the StimaWELL® 120MTRS is
supplied from a power source free
of disruption, or a battery
