Installation and connection

5.5

Electrical connection

DANGER

Risk of death due to electric shock!

All electrical work must be carried out by quali

fi

ed electri-

cians only.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.

5.5.1

Connecting the motor

Follow the instructions of the motor manufacturer.

1. Connect the motor according to the connection diagram.
2. Make sure no danger arises due to electric power.
3. Install an EMERGENCY STOP switch.

5.5.2

Checking the direction of rotation

Only possible when starting up (

→

6.2 Commissioning,

Page 20).

5.6

Performing the hydrostatic test

Only necessary if the entire system needs to be tested
under pressure.

NOTE

Material damage due to bursting of pump casing.

Testing pressure must not exceed the permissible pump
pressure (

→

documents for the particular order).

Make sure the testing pressure does not exceed the per-
missible pump pressure.
–

If necessary, do not perform pressure test on the pump.
