5.3 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 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 position the centrifuge 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.
5.4 Power Supply
5.4.1 Connection
The operating voltage on the name plate must correspond to the local
supply voltage!
SIGMA
laboratory centrifuges are units of safety class I and
have a three-wire power cord with a IEC C13 connector. They are
equipped with temperature fuses.
Switch the unit off by actuating the mains power switch.
If they have tripped, let the fuses cool down for approximately
two minutes.
Switch the unit on. The fuses are reactivated.
5.4.2 Fuses
Typically, the centrifuges must be protected on-site with 16 Amp L or
B fuses.
