T
is the supply AC voltage before the test level is applied.
Directives and manufacturer's declaration – Immunity to electromagnetic disturbance
THERA-Trainer is designed for operation in an electromagnetic environment as described below. The customer
or the user of the THERA-Trainer should make sure that the unit is used in such an environment.
Immunity test EC 60601 test level Level of conformity Directive for electromagnetic
environment
Static discharge

Floors should be wooden, concrete
or ceramic tiled. If the floor contains
synthetic materials, the relative air
humidity must be at least 30 %.

If the user of the THERA-Trainer
requires continuous functioning in
case of power supply interruptions,
we recommend using a non-inter-
ruptible power system or a battery
to supply the THERA-Trainer.

in accordance with
IEC 61000-4-8
3 A/m 3 A/m Magnetic fields at mains frequency
should correspond to the typical
values for business and hospital
environments.
