Initial Start-Up - Speck pumpen 2 VGX Series Installation And Operation Manual

Please follow the assembly instructions sequence:
– The pump must be installed horizontally.
– Metal pipes must not overstress the pump connections.
5.2
Electrical: Electrical connection only by a qualified expert!
All electrical connections should be carried out by a qualified technician in ac-
cordance with the regulations of the EVU or VDE and those of the local energy
supply companies. It must be ensured that the electrical data on the name plate
accords with the power supply available. Motors must be connected to a motor
protection switch.
For singel-phase pumps, a thermal overload protection is installed that swit-
ches off automatically if the pump is overloaded and switches on again after the
pump has cooled down. In the case of three-phase current pumps, a correctly
dimensioned motor protection switch must be provided for the owner.
For pumps with a three-phase motor, care must be taken to ensure the correct
rotational direction when the pump is put into operation.
Please note that the correct rotational direction is indicated with an arrow on the
motor.
