Introduction
EN About this guide
This guide contains information regarding the electrical installation of three-phase device 208V/16A
version together with the power cord adapter CEE 208V/16A 3P+PE. It is addressed to electricians or
persons with similar expert knowledge.
Installers must read and understand the guide before installation. The installer should conform to all
safety precautions in the document and local regulations when installing a Buchi device. Information
about the warning message concept can be found in the operation manual, section "Safety".
No technical modifications may be made to the device without the prior written agreement of Buchi.
Unauthorized modifications may affect the system safety and result in accidents.

EN General safety rules
Quality and safety of an electrical installation
Quality and safety will be assured only if the following control procedures are respected:
• The electrical installation is conform to all applicable standards and regulations
• The electrical installation equipment comply with applicable standards and regulations
• Periodic checks of the installation / the installed device are performed according to applicable
standards and regulations
Basic installation requirements and tests
Prior to installation some general electrical tests and visual inspections of the power supply network
must be carried out.
These tests are made according to local regulations, which may differ slightly from one country to
another. However, the basic principles are common and aim at the observance of basic safety rules in
the design and realization of the installation.
A standard set of tests includes:
• Insulation tests of all cable and wiring conductors of the supply installation, between phases and
between phases and ground
• Continuity and conductivity tests of protective, equipotential and ground-bonding conductors
• Verification of allowable load per circuit
• Where appropriate, verification that all exposed- and extraneous metallic parts such as distritutor
boxes are properly grounded
• Clearance check according to the installation requirement data of the device manual
These tests and checks are basic but not exhaustive for the majority of installation sites! Apply to local
regulations and standards for more information.
!Danger
Risk of death or fatal injury by electric current.
• Do not install the device when missing or ineffective protective features are detected
• Only install and operate the device at power networks and in environments that agree with the
specifications given on the type plate
• Disconnect power supply before removing cover
• Cover may only be opened by instructed persons
NOTE
IEC 60364-6 and related standards are based on an international consensus for such tests, intended
to cover all the safety measures and approved installation practices required in most cases.

Installation
Electrical supply
The used mains circuit has to:
• Provide the voltage 208-220VAC and frequency 60Hz. Power consumption 6000 VA.
• Be equipped with adequate fusage and electrical safety measures, in particular proper grounding
Suggested installation: Circuit breaker 16A with trigger characteristic B or C and residual current.
Circuit breaker (RCCB) also known as ground fault circuit interrupter with trigger current of 30mA.
See also technical data of all components regarding the different system requirements and maximum
power consumption!
NOTE
External power switches must meet IEC 60947-1 and IEC 60947-3 requirements. Such devices must
be clearly labeled and accessible at any time.
!Danger
Risk of death or fatal injury by electric current.
• Supply wires must not be under voltage prior to and during installation
• Do not install the device when missing or ineffective protective features are detected
• Only install and operate the device at power networks and in environments that agree
with the specifications given on the type plate
Notice
Risk of device damage by wrong mains supply.
• External mains supply must meet the voltage given on the type plate
• Check for proper grounding

6Installation Guide – Lyovapor L-300 - 208V 60hz
L-300 is by default equipped with power plug
Multi-phase devices
To cut off the power for multi-phase devices, an external power switch is installed on the back of the
device. This switch must be easy accessible for fast access.
The switch must be accessible at any time during operation!
Adapter CEE 208V/16A 3P + PE:
• If CEE 208V/16A is not available please use the adapter 11066356
• Install a local power plug with strain relief
• Use high-quality plugs (e.g. solid metal conductors only)
• Flexible wire ends must be equipped with a wire end ferrule
NOTE
• Additional electrical safety measures such as residual current breakers may be necessary to
meet local laws and regulations!
• External connections and extension lines must be provided with a grounded conductor lead
(3-pole couplings, cord or plug equipment). All used power cords must meet the input power
requirements.
• The grounding wire must be at least 30 mm longer, compared to all other live wires to ensure
safe grounding in case of a wire fixture or strain relief failure. See drawings!

Steps to finish the installation
Perform the following steps to finish the installation:
• Run an electrical safety test according to the local regulations if applicable. Insulation calss for the
L-300 is IP20.
• Check external power switches and other installed safety devices for functionality.
• Inform the operator / customer about external power switches or the location of the power plug.
• Before switching on the device for the first time, see operation manual for information about how to
establish suitable startup conditions!
Notice
Risk of device damage by faulty operation
• Consult operation manual for information about working liquids or other initial device
preparations for a functional test
