Electrical connection

The relevant standards (such as EN standards),
country-specific regulations (such as VDE in
Germany), and the regulations of the local
power supply companies must be observed.
Attention ! Never put the mains plug or a free
lead end in water! If water gets into the plug,
this can cause malfunctions and damage.
The pump is provided with a winding thermo-
stat. In case of unacceptably high temperatures
it switches off the pump to protect it against
BS TS
possible damage. Unacceptably high tempera-
225 325
tures may result e.g. from dry running or me-
230 325 chanical or electrical overload.

nect the device from the mains before remedy-

ing the fault! In order to do this, unplug the
pump from the mains supply or remove the
pre-fuses of the pump controls!

Observe the operating voltage (see the type
plate)! Only connect the pump to sockets that
have been installed properly in accordance
with the regulations and are fitted with a 16 A
(delay) fuse.
Pumps without built-in level control can also
be operated automatically through the use of
our level controls. Our ready to connect level
BS TS
controls can be installed without specific elec-
255 280
trotechnical skills.

The pump must only be operated with the
standard motor protection plug. Models with-
out motor protection plug must only be oper-

PUMPEN. These pumps must be connected by
170 120
a qualified electrician.

The overload protection (only for D and DS)
must be set to the nominal current of the pump
200 150
(see type plate) + 10%. If the motor protection
210 160
plug or the level control require to be opened
in order to reset or set the overload protection,
175
this must only be done by a qualified electri-
cian!
Only qualified electricians may carry
out electrical works to the pump or
the controls.
The pump is switched on again auto-
matically after cooling down - risk of
injury! For this reason, always discon-
Disconnect the device or the pump
from the power supply before open-
ing!
If there is a blockage in the pump, the overload
protection may be triggered. After rectifying
the fault the "reset" button on the motor pro-
tection plug must be pressed to switch the
pump on again. Pumps which are operated
with a separate level control have the overload
protection in the level control.
Rotational direction
The rotational direction must be checked be-
fore installation! If the rotational direction is
correct, the start-up jolt should be in the oppo-
site direction to the rotational direction arrow
on the motor housing. The wrong rotational
direction is also indicated if the pump performs
inadequately when installed, or if loud noises
can be heard during operation. If the rotational
direction is wrong, 2 phases of the supply cable
must be swapped over.
The start-up jolt can be very forceful.
Installation
The pump must be installed as shown in the
examples. For installations in accordance with
DIN EN 12056-4, the pressure pipe must be laid
in a loop above the local backflow level and
protected with a backflow prevention valve.
A correspondingly larger diameter pipe should
be used for longer pressure pipelines to avoid
pipe friction losses.
In contrast to pumps with built-in level control,
the ON and OFF switching heights of pumps
without built-in level control are variable by the
use of a separate level control.
Permanent venting of the ring housing may be
necessary if the pump runs dry from time to
time (pressure outlet surfaced). This can occur
for example if the residual water in the collect-
ing chamber evaporates or if the pump runs in
"snore" mode during the test run.
To vent the pump housing on pumps US 151,
US 251 and US 253 the pressure pipe must be
drilled above the pressure outlet to provide a 6
mm drill-hole. On all other pumps, the M8 hex-
agon socket screw under the (brass) oil screw
must be removed.
Attention!If the pump is malfunctioning, part
of the contents of the oil reservoir could escape
into the pumping medium.
