7.2 Electrical connection
ATTENTION!
WARNING! Danger of electric shock
The electrical connection must be made by an electrician approved by the
local utility company in accordance with the locally valid regulations (e.g.
VDE regulations).
 The mains connecting cable (Fig. 1.1 Appendix page II item
8) is inseparably connected to the pump.
ATTENTION!
Caution! Danger of damage to the pump
The cable must be connected in the factory. A subsequent connection is
not possible.
ATTENTION!
Warning! Danger of electric shock!
If the cable has been disconnected from the pump by force, there is
danger of personal injury:
When the pump is in generator operation (with the rotor driven), a
dangerous voltage may be present at the module contacts.
Do not stick any sharp objects (nails, screwdrivers, wire etc.) into the
module contacts.
The free end must be connected in the system's switch box (Fig.
4.1 Appendix page IV).
 Black/brown flexible wire: L1 (phase)
 Blue flexible wire: N (neutral conductor)
 Green-yellow flexible wire: (protective earth)
 The mains connection cable must be routed into the
system's switch box using a strain relief. The strain relief and
impermeability against dripping water/condensate must be
ensured. If necessary, the cable must be furnished with a
drip-off loop in order to prevent water from entering the
switch box.
 The following minimum requirements must be fulfilled in the
event of a switch-off via an external/on-site circuit relay:
 Nominal current > 10 A
 Nominal voltage 250 V AC
 Leakage current per pump I
eff
3.5 mA (according to EN
60335)
 No on-site motor protection switch is necessary. If a motor
protection switch is already part of the system, this must be
bypassed or set to the maximum possible current value.
 The pump can be protected using a fault current protection
switch.
Fault current designation: or
 Current type and voltage of the mains connection must be in
accordance with the specifications on the type plate.
 Mains connection voltage: 1 ~ 230 V, 50/60 Hz, DIN IEC
60038.
 Line side fuse protection: See type plate,
 The pump/system must be earthed according to regulations.
ATTENTION!
CAUTION! Danger of damage to the pump
All poles of the pump must be disconnected from the mains within the
switch box during insulation tests with a high-voltage generator.
 The control cable (Fig. 1.1 Appendix page II) is inseparably
connected to the pump (like the mains cable).
 The strain relief of the cable and impermeability against
dripping water/condensate must be ensured. If necessary,
the cable must be furnished with a drip-off loop in order to
prevent water from entering the switch box. The control
cable covers the following control functions:
 Control via analogue signal 0-10V (4-core cable) (Fig. 4.2
Appendix page IV):
 - Flexible wire no. 1 (brown): 0...10 V signal ground
(GND)
 Flexible wire no. 2 (white): 0...10 V signal
 Flexible wire no. 3 (blue): Collective fault signal
 Flexible wire no. 4 (black): Collective fault signal
Collective fault signal: The collective fault signal is a floating
NC contact (closed when de-energized).
 Contact load: min. permissible: 12 V DC, 10 mA, 
max. permissible: 250 V AC, 1 A.
 Switching frequency:
 Switch-on/switch-off via line voltage 
T 20 times / 24 h.
 Switch-on/switch-off via 0...10 V T 20 times / h.
 Min. interval between 2 operations >= 5 s
 All connecting lines must be connected in such a way that
there is no contact with pipework and/or the pump/motor
casing.
