• 230 V
Δ
: This specification has the same meaning as 230/400 V.
• 400 V
Δ
: In a circuit with 400 V between the phases, these motors are connected in a
delta configuration (figure 8). Remark: Motors with a power of 3 kW and higher are
usually not connected directly in delta configuration (the initial current rises to too high
a value immediately during start-up. The motor starts, connected in star configuration
(see figure 9: switches D1 and D3 closed) and then after a few seconds as the motor
comes up to speed is switched to delta configuration (switches D1 and D2 closed
and D3 open). This is achieved in a star-delta connection.
• 400/690 V : This specification has the same meaning as 400 V

3.8 Combustion engines
The regulations for combustion engine are included with the delivery of the group, in
case these are not present, make urgent contact with us.
In addition to these directions, for all combustion engines, the following points must be
complied with :
• Comply with the local safety regulations
• The exhaust pipe for the combustion gases must be screened against accidental
contact
• The starting cord or handle must be automatically uncoupled, once the motor is
started
• The rotation speed of the motor is set in the factory and must NOT be changed
• Before starting the motor, check the oil level while putting the pump in horizontal
position.
!
In view of the toxicity of the exhaust gases, never run the engine in a closed
room.
!
Never top up with fuel while the motor is running.
