UPE 70-25PK - UPE 120-32K

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 connection cable must be connected directly for

the pumps UPE 100-25 K, UPE 100-32 K and UPE 120-
32 K. To do this, loosen the screw, remove the cover, feed
the cable through the left strain relief and connect it.
The mains cable of the UPE 70-25 PK and UPE 70-32 PK
pumps is equipped with a Molex connector, which is
mounted on the rear side of the pump head (in the scope of
supply).
ATTENTION!
On-site, the signal input of the pumps UPE 70-25 PK and UPE 70-32 PK is
sealed with a connector, (see Fig. 7.1 on page 7 ), which must be removed
when connecting a signal line.

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 on 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 on page VIII).
 Black/brown flexible wire:
 Blue flexible wire:
 Green-yellow wire:
 The mains connection cable must be routed into the sys-
tem'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

No on-site motor circuit breaker is necessary. If a motor cir-

cuit breaker is already part of the system, this must be by-
passed or set to the maximum possible current value.

The pump can be protected using a RCD circuit breaker.

Labelling RCD:
 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.
Like the mains cable, the control cable for the pump

UPE 70-25 PK or UPE 70-32 PK (Fig. 1.2 Appendix on
page III) is connected to the pump via a plug connection
(special accessories).
 The strain relief of the cable and impermeability against drip-
ping water/condensate must be ensured. If necessary, the
cable must be furnished with a drip-off loop in order to pre-
vent water from entering the switch box. The control cable
covers the following control functions:
 Control via analogue signal PWM (3-core cable) (Fig. 4.2
Appendix on page VIII):
 Flexible wire no. 1 (brown): PWM signal
 Flexible wire no. 2 (blue/grey): PWM signal ground
(GND)
 Flexible wire no. 3 (black): Bidirectional PWM
Collective fault signal: The collective fault signal is a floating
NC contact (closed when de-energized). (pumps UPE 100-25 K,
UPE 100-32 K and UPE 120-32 K only)
 Contact load:
 Switching frequency:
 Switch-on/switch-off via line voltage
 T 20 times / 24 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.
