Exhaust Line
An exhaust line is required to remove the waste gas of the pre-vacuum pump and to transmit it to
the outside.
If toxic chemicals or biological specimens are used an exhaust line is recommended to remove the
waste gas of the pre-vacuum pump and to transmit it to the outside.
Electrical Supplies
Parameter
Requirement
Nominal AC volt-
age
208–230 VAC (±10 %), L1/N(L2)/PE
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 power cord
3 × AWG10 UL-style (3 m long) and a CEE-connector (Type 32 A-6 h;
200 to 230 V, 2P+PE). Alternatively the microscope can be installed
directly to a switchable power distribution terminal which can be se-
cured against accidental re-activation.
Power consump-
tion
Max. 3.7 kVA, dependent on accessories
Maximum current
16 A
Circuit breaker (at
house installation)
25 A (type K)
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 an equipotential bonding bar. An
exclusive grounding connection to earth must be provided, i.e. the
grounding terminal must not be common to other electrical equip-
ment. A grounding wire AWG10 is delivered with the microscope.
