6.2. Electrical connection
Only have the pump connected by an authorized specialist.
Only have the pump connected when the power supply is disconnected.
When connecting the device to a power source, the relevant norms,
directives, regulations and technical standards must be observed.
The controller must only be operated in accordance with the
ESD (Electrostatic Discharge) safety standards.
Connecting the pump
Make sure that the power supply data match the data on the motor's type
plate. The current consumption can be found on the type plate.
Check actuation algorithm for 2-phase stepping motor (e.g. with KNF
controller see accessory list in chapter 10)
KNF recommendation: Bipolar winding assignment, current-
driven actuation (chopper operation), key data can be found on
the type plate and the data sheet.
The latest algorithms can be found in the literature.
