12.11.1. Assembly and disassembly
• Pull both plugs from the mains choke coil.
• Undo the fastening screws of the mains choke coil.
• Replace the mains choke coil.
12.11.2. Short the mains choke coil
In countries, in which the European standard EN 61000-3-2 applies it is not
allowed to short the mains choke coil.
The mains choke coil reduces the mains input current below the limit values
stated in the above mentioned European standard.
If the centrifuge is run with undervoltage, that is mains frequency 50 Hz with a voltage
< 205 V or mains frequency 60 Hz with a voltage < 210 V the voltage drop of the mains
choke coil can cause the error FU / CCI - ERROR 62.
The short of the mains choke coil will increase the supply voltage of the frequency
converter.
• Pull both plugs (A) from the mains choke coil, see Figure 1.
• Cut off both plugs and connect the ends of both cables together with a luster terminal
(B), see Figure 2.
