Pump with dual-voltage motor:
• Check the power source and the pump’s
rating plate to be sure that the power source
and the equipment match in voltage, phase,
and frequency.
• Check that the voltage selection switch is
positioned correctly. Check every time be-
fore starting the pump. Note: If the pump is
switched on with wrong voltage selection,
the motor may be damaged!
Changing the selection at the voltage se-
lection switch:
• Change the selection at the voltage se-
lection switch only, if the pump is un-
plugged from the power source.
1. Disconnect the electrical power cord.
2. Use a screw driver to adjust the voltage se-
lection switch to the supply voltage:
”115/120” corresponds to 100-120 V and
”230/240” corresponds to 200-230 V.

• Check the power source and the pump’s
rating plate to be sure that the power source
and the equipment match in voltage, phase,
and frequency.
Connect the supply voltage and the control
signal to the pump’s control line (see „Control-
ling the MD 1C VARIO-SP“, pg. 43).
Switch the supply voltage and, if required, the
control signal on.
