7 Commissioning/shutdown
Ensure that the following requirements are met prior to commissioning:
▪
The pump has been vented and primed with the fluid to be handled.
▪
Flow through the pump is in the design direction specified in order to avoid
generator operation of PumpDrive.
▪
A sudden start-up of the motor or pump set does not result in personal injury or
damage to machinery.
▪
No capacitive loads, for example for reactive current compensation, are
connected to the outputs of the device.
▪
The mains voltage is in the range approved for PumpDrive.
▪
PumpDrive has been properly connected to the power supply. (
▪
All enable and start commands that start PumpDrive are deactivated (digital
input 1 for single-pump operation and digital inputs 1 and 2 for multiple pump
operation).
▪
No voltage is applied to the power supply module of PumpDrive.
▪
PumpDrive or the pump set must not be loaded above the permissible nominal
power.
▪
If PumpDrive is going to be used in multiple pump operation, note (
7.1.3 Page 62) prior to commissioning.

Setting motor parameters
Motor-mounted PumpDrive model:
The motor parameters have been set at the factory.
Cabinet-mounted or wall-mounted PumpDrive model:
The factory-set motor parameters must be compared with the data provided on the
motor rating plate and adjusted, if required.
