PR 5610 Installation Manual
6 Sartorius
1.3.2 Electrostatically sensitive components
This instrument contains electrostatically sensitive components. Therefore, potential equalization must be
provided when working at the open instrument (antistatic protection).
Opening the instrument
CAUTION
DANGER TO LIFE !
Working at the switched on unit may be dangerous to life. Disconnect the
instrument from the supply voltage! When removing covers or parts by means of
tools, live parts or terminals may be exposed. Capacitors in the unit may still be
charged also after disconnecting the unit from all voltage sources. Before
selecting a different supply voltage and before replacing the loadcell fuse, the
unit must be disconnected from all voltage sources.
1.3.2.1 Earthing
Earthing of the unit must be via the protective earth conductor PE.
1.3.3 Protective
earth
The connecting cable of the unit must comply with the regulations in accordance with VDE 0411 or EN61010.
The power cable must contain a protective earth conductor, which must not be interrupted inside or outside
these units (e.g. by using an extension cable without protective earth). The protective earth must be connected
with terminal PE in the power connecting block. Before commissioning, acceptance of the installation by a
technically responsible expert is required.
Power connection PR 5610/X0
The PR 5610/X0 is designed for 230 V AC / 115 V AC with 50 to 60 Hz supply
The adjusted operating voltage must correspond to the nominal power voltage.
Changing over from 230 V (
factory setting
) to 115 V is done by means of a
rotary switch, which can be actuated using a screwdriver. Turn the switch to
the required voltage marked below the arrow. Power connecting terminals,
supply voltage selector switch and transformer are located on board 1, left
above the row of cable glands.
Caution: The power cable conductors must be tied together with a cable strap shortly before the terminal block!
As the unit has no power switch, it is ready for operation immediately after connecting the supply voltage. The
firm power connection must be protected with a fuse. Additionally, an interruption (safely) of both lines of the
supply voltage must be possible, e.g. by means of a switch or a power connector.
