3.4. Connecting To Mains Power
The pump is equipped with a frequency variable motor for
speed control as standard:
207 ... 253 V;
50/60 Hz,
104 ... 127 V;
50/60 Hz,
90 ... 110 V/AC;
50/60 Hz.
➡
Carry out electrical connections in accordance with local
regulations.
– Voltage and frequency values on the rating plate must
concur with mains voltage and mains frequency values.
– Attach pump to mains using the protective conductor
(PE) always.
– For pumps without a power plug on the connecting
cable, have the mains connection made by qualified
personnel only.
Mains connection must always apply a contact
to the earthed conductor, otherwise electrical
voltage could occur on the pump housing.
WARNING
Dangerously high voltage in the terminal
box!
Before opening the terminal box disconnect the
mains plug and wait for five minutes, until the
intermediate circuit voltage (> 300 V) has
discharged.
➡
Switch ON/OFF motor (pump) with release switch 14.
– In case of an error (e.g. overheating, overcurrent,
overvoltage) the electronics of the frequency converter
switches off the motor automatically. If the error doesn´t
exist any longer, the pump restarts automatically.
Recommend fuse for mains connection:
207 ... 253 V/AC
-->10 A,
104 ... 127 V/AC
-->16 A,
90 ... 110 V/AC
-->16 A.
Reset of the drive after triple occurance
The frequency converter drive is blocked, after an error has
occured triple in quick succession.
➡
Disconnect the frequency converter from the mains, for
CAUTION
