DANGER
Earth conductor not properly connected
Danger of death from electric shock!
▷ Never operate the motor without earth conductor.
▷ The earth conductor must be connected by a professional electrician only.
WARNING
Incorrect connection to the mains
Damage to the power supply network, short circuit!
▷ Observe the technical specifications of the local energy supply companies.
NOTE
Only VDS-approved switchgear shall be used for pump sets in sprinkler
installations.
Due to the special conditions of pumps in fire protection applications, switchgear
with overcurrent relay must not be used, for example.
1. Check the available mains voltage against the data on the name plate.
2. Select an appropriate start-up method and observe the respective requirements.
3. Check the starting method in the data sheet and select the corresponding circuit
diagram.
4. Connect the power cable including earth conductor.
5. Remove the safety notice from the motor lead ends and attach it near the actual
place of connection.
In the case of UMA-S 150, UMA-S 200 and UMA-S 250 submersible motors, the power
cable cores are connected together at the time of supply. Prior to disconnecting
them, make sure that the motor is not rotating (e.g. due to backflow in the pump
caused by a lack of or a defective check valve). Observe the safety regulations that
apply to work involving electrical hazards. Verify that the equipment is de-energised.
NOTE
Connect the shielded motor power cable with the exposed shield as short as
possible and the shield ends having contact over a large area. Interruptions of the
shield must be compliant with EMC
equipment manufacturers.
Single-phase (1~) motors with one power cable for DOL starting
For this motor type a starting device is required. The starting device is included in the
scope of supply.
1. Check the terminal assignment diagram. Wire the starting device in accordance
with the illustration and the manufacturer's product literature.
