EX3™ Stepper English
TABLE 2
GUIDANCE AND MANUFACTURER'S DECLARATION - ELECTROMAGNETIC IMMUNITY
The EX3 Stepper is intended for use in the electromagnetic environment specified below. The customer or the user of the EX3 Stepper should assure that it is
used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment - guidance
Electrostatic discharge
(ESD)
IEC 61000-4-2
±6 kV contact

Not Applicable Mains power quality should be that of a typical commercial or
hospital environment.
If the user of the EX3 Stepper requires continued operation during
power mains interruptions, it is recommended that the EX3 Stepper be
powered from an uninterruptible power supply or a battery.
