The provided electrical connection must be in accordance with the ap-
plicable electrical codes for the country of installation. In order to
avoid disturbance from other installed machines, ZEISS recommends
using a separate power connection to the main distribution panel.
Protection class
Class I
Nominal frequency
50–60 Hz
Momentary inter-
ruption
Less than a half cycle
System connection
The microscope is delivered with a 3 m long power cord that is
equipped with a 200–250 V
AC
CEE MALE PLUG 2P3W 6h 16A (blue)
according to IEC 60309.
The supplied connection cable must not be replaced with another
one. Otherwise, the conformity with listed standards becomes invalid.
The building installation should provide the corresponding 200–250
V
AC
CEE FEMALE RECEPTACLE 2P3W 6h 16A (blue) with the correct
wiring 1/N/PE or 2/PE and the desired approvals of the country used.
To avoid disturbance from other installed machines Carl Zeiss Mi-
croscopy recommends to use a separate power connection to the
main distribution panel.
Power consump-
tion
Max. 3 kVA, dependent on accessories
Circuit breaker (at
house installation)
16 A Type C
Ampere interrupt-
ing capacity (AIC)
Min. 10,000 A
rms
Protective ground
High leakage currents are present in the microscope. Therefore, the
microscope has to be connected to a separate protective ground.
An exclusive grounding connection to earth must be provided as part
of the building installation, i.e. a grounding screw terminal (Ø 8 mm)
which is directly connected to the PE of the FEMALE RECEPTACLE as
short as possible. (see picture)
This grounding connection must not be common to other electrical
equipment.
