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.

Type of connection
DANGER
The operating voltage on the name plate must correspond to the local
supply voltage!
CAUTION
The mains power plug is an isolating device which is why it must be
accessible at all times.
Sigma centrifuges are units of protection class I. The centrifuges of this
model series have a three-wire power cord with a fixed cable. They are
equipped with a mains power switch with an integrated thermal circuit
breaker.
• Switch the unit off by actuating the mains power switch.
• If it has tripped, let the circuit breaker cool for approximately 2 minutes.
• Switch the unit on.
The centrifuge is now ready for operation.
