5.2 Electrical connections
The Rotavapor
®
is aimed to be installed stationary and is not equipped with a power plug. The elec-
trical installation must be performed by an electrician or equivalent specialist in any case. After the
installation procedure an electrical safety test must be performed to verify a safe system condition
such as sucient grounding.
Mobile / stationary installation
• In mobile mode the instrument is connected to mains via a power plug. The plug must be freely
accessible at any time to be unplugged in case of emergency.
• In case the instrument is installed stationary (without power plug) an emergency power-o device
must be installed in the vicinity of the Rotavapor® with free access granted.
Demands on the mains circuit
The mains circuit must
• provide the voltage that is given on the type plate of the instrument.
• be able to handle the load of the connected instruments.
• be equipped with adequat fusage and electrical safety measures, in particular proper grounding.
For details about the installation requirements, see "Installation Instruction R-220 Pro" document.
See also technical data (section 3.2) of all components regarding the dierent minimum system
requirements!
NOTE
• Additional electrical safety measures such as residual current breakers may be necessary to meet
local laws and regulations!
• External power switches (e.g. emergency stop switches) must meet IEC 60947-1 and IEC
60947-3 requirements. Such devices must be clearly labeled and accessible at any time.
• 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.
