CAUTION
Contamination in the pressure booster system
Damage to the pumps!
▷
Clean the tank before filling it.
The tank must be connected mechanically and electrically to the pressure booster
system prior to commissioning of the system.
5.6 Electrical connection
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷
Observe the technical specifications of the local energy supply companies.
Connection to power supply is effected by means of a 230 V plug in accordance with
VDE 0100.
Site-supplied fusing: 16 A (max).
NOTE
In individual cases, an earth leakage circuit breaker may trip when the pressure
booster system is first commissioned. This may be caused by total discharge of the
intermediate circuit.
5.6.1 Sizing the power cable
The cross-section of the power cable must be sized for the total rated power
requirement.
5.6.2 Connecting the external dry running protection device (optional)
ü An M12 plug is included in the scope of supply (the pressure booster system has a
connection for an external, operator-supplied dry running protection device.)
NOTE
Pressure booster system does not start up
If the pressure booster system is equipped with a connection for an external dry
running protection device, an external, operator-supplied dry running protection
device must be connected. When the external dry running protection device (e.g.
float switch) is not connected, the pressure booster system will not start.
1. Connect the cores of the external dry running protection device at pin 2 and
pin 4 of the M12 plug. The contact must be a normally closed contact.
