Connection: Pump without a plug
DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death due to electric shock!
- Electrical work must be carried out by a qualified electrician!
- Observe local regulations!
CAUTION
Irreparable damage as a result of water penetration
Connection cables without plugs feature bare cable ends. Water may penetrate the connection cable and pump via these bare cable ends. This will destroy both the connection cable and the pump. Never immerse the bare end of the connection cable in fluid. Firmly seal it during storage.
The pump has a connection cable with bare cable end. The pump must be permanently connected to a switchgear. Observe the following points:
- Earth the device properly!
- Provide a motor protection switch!
- The minimum requirement is a thermal relay/motor protection switch with temperature compensation, differential trip and reactivation lock according to local regulations.
- Install the mains disconnection device!
- Minimum requirement: Main switch with all-pole disconnection.
Pump with single-phase AC motor
To connect the pump firmly to the switchgear, cut off the plug. Carry out connection to a switchgear as follows:
Wire colour | Terminal in switchgear |
|---|---|
Brown (bn) | L (phase) |
Blue (bl) | N (neutral conductor) |
Green/yellow (gn-ye) | Earth (protective earth conductor) |
Pump with three-phase AC motor
The pump is suitable for connection to a clockwise rotating field. Check the rotating field with a rotating-field-testing device before connection and correct if necessary. Carry out connection to a switchgear as follows:
Wire colour | Terminal in switchgear |
|---|---|
Brown (bn) | U |
Black (bk) | V |
Blue (bl) | W |
Green/yellow (gn-ye) | Earth (protective earth conductor) |
Adjust the motor protection
Set the motor protection switch to the rated current (see rating plate).
