►
Ground pipes and pump to dissipate electric charge.
Electrical connection may only be performed by a qualified elec-
trician.
Procedure
1. Heed the connection values on the motor's rating plate. En-
sure that the specified current and voltage values are not ex-
ceeded.
2. Only connect the motor to fuse-protected circuits to prevent
excessive current consumption.
3. Connect the motor according to the circuit diagram in the
terminal box of the motor.
4. Turn on the motor for 2 to 3 seconds. Check the direction of
rotation of the pump and the motor fan wheel, see
"Direction of rotation left," page 12
. Ensure that the pump is filled with me-
dium to prevent dry running of the shaft seal.
