9. Install the motor using suitable hoisting gear and tighten the connection between lan-
tern and motor.
10. Push the forked spacer (Fig. 47, Item 10) between the lantern and coupling. The forked
spacer must sit there without any play.
11. Slightly tighten the coupling screws (Fig. I/II/III, Item 1.41) first until the coupling half
shells are in contact with the shims.
12. Afterwards, screw the coupling together evenly. In doing so, the specified distance
between the lantern and the coupling of 5 mm is automatically adjusted via the forked
spacer.
13. Remove the forked spacer.
14. If present, attach the pressure measurement lines of the differential pressure sensor.
15. Install the coupling guard.
16. Reattach the mains connection and, if present, the cable of the differential pressure
sensor.
NOTICE
Observe the steps for commissioning (see "Commissioning" section).
17. Open the shut-off devices upstream and downstream of the pump.
18. Reset the fuse.
DANGER
Danger of death due to electrical current!
Improper conduct when carrying out electrical work can lead to death
due to electric shock!
• Any work on electrical devices may only be carried out by a qualified
electrician.
• Before commencing work, switch off the voltage in the unit, secure it
against being switched on again and wait 5 min.
• Check whether all connections (including potential-free contacts) are
voltage-free.
• Never poke around in the openings on the electronic module or insert
anything into them.
• Any damage to the pump connection cable should only ever be recti-
fied by a qualified electrician.
• Observe the installation and operating instructions for the pump, mo-
tor and other accessories.
• Reinstall any uninstalled safety devices, such as module covers, once
the work is complete.
DANGER
Danger of death due to contact voltage! Even when it is dis-
connected, high contact voltages can still occur in the elec-
tronic module due to non-discharged capacitors.
Touching live parts will result in serious injuries or death!
• Before working on the pump, interrupt the supply voltage and wait
5 min!
• Check whether all connections (including potential-free contacts) are
voltage-free.
• Never poke around in the openings of the electronic module or insert
anything into them!
