NOTE:
UT is the a.c. mains voltage prior to application of the test level.
Guidance and manufacturer’s declaration – electromagnetic immunity
The Optima XR646 is intended for use in the electromagnetic environment specified below. The customer or the user of the Optima
XR646 should assure that it is used in such an environment.

user of the system requires continued
operation during power mains interruptions, it
is recommended that the system be powered
from an un-interruptible power supply or a
battery.
