Connection to power supply
DANGER
Work on the pressure booster system by unqualified personnel
Danger of death from electric shock!
▷
Always have the electrical connections installed by a trained electrician.
▷
Comply with regulation IEC 30364.
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷
Observe the technical specifications of the local energy supply companies.
The circuit diagrams are included in the control cabinet of the pressure booster
system, where they must remain when not in use.
The product literature of the switchgear and controlgear assembly supplied with the
pressure booster system includes a list of the electrical components installed. When
ordering spare parts for electrical components, please always indicate the circuit
diagram number.
6.7.1 Sizing the power cable
The cross-section of the power cable must be sized for the total rated power
requirement.
6.7.2 Connecting the pressure booster system
Connect the pressure booster system to the power supply via terminals L1, L2, L3, PE
and N as shown in the enclosed circuit diagram.
Observe the data given on the name plate.
6.7.3 Digital inputs
Terminal strip P4, terminals 13 to 20. (
PumpDrive is equipped with six digital inputs.
Digital inputs 1 and 6 are factory-defaulted.
Digital input 1 is the External ON/OFF input, which is connected to terminal P4-13 in
as-delivered condition. If the pressure booster system is equipped with dry-running
protection, this is connected in series with the External ON/OFF input.
The functions of digital inputs 2 to 5 can be parameterised by the user at the control
panel. To connect the inputs use terminal P4-13 (+24 V DC). If an external 24 V DC
source is to be used, the neutral conductor from this source must be connected to
terminal P4-20.
Parameterisation (
6.7.4 Relay outputs
Terminal strip P7, terminals 1 to 4. (
In as-delivered condition the relay outputs are parameterised as volt-free contacts for
"No alarm" (relay 1) and "Operation" (relay 2). Different messages can be assigned
to these relay outputs via the control panel.
Parameterisation (
6.7.5 Analog inputs
Terminal strip P7, terminals 5 to 10. (
Analog input 1 can be used for external setpoint adjustment.
Analog input 2 is assigned to the pressure transmitter (feedback value transmitter) as
a standard, which, however, is connected to the mains-motor-PTC terminal strip. (
