2.5.2 Guidelines and manufacturer's statement - Electromagnetic im‐
munity
The KEY Laser 1243 is for use in an environment like the one cited below. The
operator of the KEY Laser 1243 must ensure that it is operated in such an environ‐
ment.
Immunity tests IEC 60601 test level Conformance level Electromagnetic environ‐
ment - guidelines
Electrostatic discharge
(ESD) according to IEC
61000-4-2
± 6 kV contact discharge ±
8 kV air discharge
± 6 kV contact discharge ±
8 kV air discharge
Floors should be made of
wood or concrete or have
ceramic tiles. When the
floor is made of synthetic
material, the relative humi‐
dity must be at least 30%.
Fast transient electrical
disturbances/ Bursts ac‐
cording to IEC 61000-4-4
± 2 kV for power lines ± 1
kV for input and output li‐
nes
± 2 kV for power lines ± 1
kV for input and output li‐
nes
The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
Surges according to IEC
61000-4-5
± 1 kV normal mode volta‐
ge ± 2 kV common-mode
voltage
± 1 kV push-pull voltage ±
2 kV common-mode volta‐
ge
The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
Voltage interruptions,
short-term interruptions
and fluctuations of the
supply voltage according
to IEC 61000-4-11
< 5% V (> 95% drop in the
VT for ½ period 40%
V(60% drop in the VT for 5
periods 70% V(30% drop
in the VT for 25 periods<
5% V(> 95% drop in the VT
for 5 s (250 periods)
< 5% V (> 95% drop in the
VT for ½ period 40%
V(60% drop in the VT for 5
periods 70% V(30% drop
in the VT for 25 periods<
5% V(> 95% drop in the VT
for 5 s (250 periods)
The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
When the user of the KEY
Laser 1243 needs conti‐
nued operation even when
the power supply is inter‐
rupted, it is recommended
to supply the KEY Laser
1243 from an uninterrup‐
ted power supply or a bat‐
tery.
Magnetic field with a sup‐
ply frequency (50/60 Hz)
according to IEC
61000-4-8
3 A/m
80 MHz – 2,5 GHz
3 A/m Magnetic fields at the
mains frequency should
correspond to typical valu‐
es in a business and hos‐
pital environment.
NOTE: V T is the alternating mains voltage before the test level is used.
