5 Set-up and connection
5.1 Installation site
Operate the centrifuge only in closed and dry rooms.
All the energy supplied to the centrifuge is converted into heat and emitted
to the ambient air.
• Ensure sufficient ventilation.
• Keep a safety distance of at least 30 cm around the centrifuge so that
the vents in the centrifuge remain fully effective.
• Do not subject the centrifuge to thermal stress, e.g. by positioning it
near heat generators.
• Avoid direct sunlight (UV radiation).
• The table must be stable and have a solid, even surface.
• Attention: During transport from cold to warmer places, condensational
water will collect inside the centrifuge. It is important to allow sufficient
time for drying (min. 24 h) before the centrifuge can be used again.
5.1.1 Type of connection
The operating voltage on the name plate must correspond to the local
supply voltage!
Sigma centrifuges are units of protection class I. The centrifuges of this
model series have a three-wire power cord with an IEC C13 connector.
The removable power cord must not be replaced with a power cord of
inadequate rating!
5.1.2 Customer-provided fuses
Typically, the centrifuge must be protected with 16 Amp L or B fuses that
are to be provided by the customer.
To ensure safe disconnection in the event of a fault, an AC/DC-sensitive
RCD (residual current device) must be integrated in the wiring system of
the building.
