3.4.2 Connection with a Freely Selected Frequency Converter
Notice safety information 0.2.
For selecting the right frequency converter for your specific application please
consult Leybold first. We recommend a frequency converter similar to the
one described in Sections 3.4.3 and 3.4.5. This frequency converter perfectly
matches the pump. A connection diagram is depicted in fig. 3.9.
Observe the information on the frequency converter provided in the
enclosed Operating Instructions. Please read these Operating Instructions
and understand the information provided before installing, operating or
doing maintenance work on the frequency converter. The frequency con-
verter must be installed in agreement with the information provided in these
Operating Instructions and in agreement with the locally applicable regula-
tions. Non-compliance with the safety information can result in serious or
even deadly injury, or may damage the products or facilities and systems
connected to the product.
Connect the pump to the correct mains voltage through the connections in
the junction box.
Do not connect the electric control circuitry to the power circuitry of the fre-
quency converter.
During operation of the pump one of the motor’s temperature sensors needs
to be monitored to ensure that the pump is shut down as soon as one of the
monitoring facilities responds. For the frequency converter recommended by
us this will be the connection at A2 and AC.
When using the connections A2 and AC to control the speed via the ana-
logue input, connect the PTO and evaluate its signal or connect the PTC
using a separate processing unit and evaluate its output signal. Note the
setting of DIP switch S4.
For the motor power supply line shielded types of cable must be used.
