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

Mains power quality should be
that of a typical commercial
or hospital environment. If the
user of the Hybresis Controller
requires continued operation
during power mains interrup-
tions, it is recommended that
the Hybresis Controller be
powered from an uninterrupted
power supply or a battery.

Power frequency magnetic
fields should be at levels char-
acteristic of a typical location
in a typical commercial or
hospital environment.
