6.8 Connection of Power Supply
Always heed the VDE regulations when connecting the powder mixer.
– Electrical connection: 1 x 400 V, 32 A or 63 A
– CEE plug in accordance with DIN 49 462 or DIN 49 463, VDE, and generally recognized
rules of technology; backup fuse: 32–160 A, depending on customer-side installed capac-
ity
– Interpoles are only approved for 32 A CEE plugs. Connection is usually made using a
plug-in connection. A switched receptacle is required for this (63 A fuse).
– The pump motors are poled at the control cabinet connection in such a way that the
pumps rotate correctly with a clockwise rotating field.
6.9 Checking Direction of Rotation of Pumps
Damage to Pumps
Damage to seals.
► The pumps on the powder mixer may not be run dry.
1. Close throttle valve V2.
2. Close drain valve V3.
3. Open metering valve V1.
4. Fill the funnel with water until the pipes are filled.
– The mechanical seals will then be wetted with water, as required.
5. Turn on the shear pump briefly (for a few seconds), and then turn off again: check if the
direction of rotation is correct. See the operator's manual for the pump.
To perform the check, observe the impeller through the discharge port on the shear
pump or the fan wheel on the motor (remove paneling). The pumps must rotate coun-
terclockwise when viewed from the top, looking down on the pump casing.
6. If the motors are running in the wrong direction, rotate the interpole in the connector (to
32 A).
