Stationary Wet-Well Installation; Electrical Connection - salmson Mini SDL Instrucciones De Instalación Y Funcionamiento

ENGLISH
7.1 Installation
The pump is designed for the following installation types: sta-
tionary and transportable wet-well installation.
CAUTION! Risk of damage to the pump!
The pump must only be suspended by a chain from the
handle provided. Never suspend or carry using the
cable!
• The pump must be installed in a frost-free place.
• The shaft must be free from coarse solids (e.g. building rub-
ble) prior to installation and commissioning.
• The pipes must be assembled stress-free. The pipes must be
attached in such a way that the pump does not bear the
weight of the pipes.
• In order to protect against possible reflux from the public sew-
age system, the pressure pipeline should be formed as a
"pipe loop". It must be placed over the locally set reflux level
(usually street level).
• When assembling the pump for stationary use, a non-return
valve and a shut-off valve with full flow cross-section should
be built into the pressure piping. In the case of double pumps
these fittings should be installed for each pump.
NOTE:
Optimally, the valves should be installed outside of the
pump, in a separate shaft (valves shaft). Where this is
not feasible, the valves should not be connected
directly to the discharge side or the pipe bend. A
device for venting the pump should be provided, oth-
erwise the insulating air cushion may not open the non-
return valve.
• "Original Salmson accessories" are recommended to ensure
the fault-free operation of the pump / installation.

7.1.1 Stationary wet-well installation

• Stationary wet-well installation (Fig. 1).
1: Foot bend with pump mounting, profiled gasket, assembly
and base fixing screws and pipe tensioner (Pos. 1.1) for two
pipes. The guide pipes (R¾" = Ø26.9 to DIN 2440) are to be
obtained by the customer.
2: Backflow preventer with unrestricted passage, cleaning
opening, ventilating device and assembly accessories
3: Shut-off valve with fitting accessories
4: Pipe bend with fitting accessories
6: Chain
See catalogue for details.
• The fixed pipe connections on the pressure side are to be pro-
vided by the customer.
• Fit and align the foot bend on the base of the shaft with the
base fastening accessories.
• Connect the pressure piping to the foot bend with the
required fittings (accessories).
• Attach the pump mounting and profiled gasket to the pump
pressure pipe connection.
• Attach the R¾" guide pipe (to be provided by the customer)
to the foot bend.
• Hang the pump from the guide pipe and carefully lower it on
the chain. The pump will lock into the right operating position
automatically and seal the delivery connection on the foot
bend by its own weight.
• Fasten the chain to the guide pipe mounting with a shackle
(provided by the customer).
7.1.2 Transportable wet-well installation
CAUTION! Risk of damage to the pump!
The pump should be prevented from falling over or
moving away from the spot where it has been installed.
• Transportable wet-well installation Mini SDL 204/1.1 ... 1.5
(Fig. 2).
6: Chain
9: Stand with fixing accessories
10a:Pipe bend R1 ¼ (inner/outer thread) with fitting accessories
See catalogue for details.
• Transportable wet-well installation Mini SDL 204/1.1 ... 2.8
(Fig. 3).
6: Chain
9: Stand with fixing accessories
10b:Pipe bend R1 ½ (inner/outer thread) with flange and fitting
accessories.
See catalogue for details.

7.2 Electrical connection

WARNING! Risk of electric shock!
Electrical connection must be carried out by an electri-
cal installer authorised by the local power supply com-
pany in accordance with the applicable local
regulations (e.g. VDE regulations).
• Check that the mains current and voltage comply with the
data on the rating plate.
• Pump must be earthed in compliance with regulations.
• Use a residual current operating device ≤ 30 mA,
• Use a disconnecting device to disconnect from the mains
with a contact gap width of min. 3 mm,
• Fuse protection: 16 A, inert or circuit breaker with C-charac-
teristic,
• The switch box for the pump(s) must be provided as an
accessory or by the customer, and must be equipped with a
protective motor switch which is to be set to the nominal
motor current as indicated on the rating plate plus approx.
twenty percent.
• Generally speaking, all switch boxes should be installed out-
side the explosive area.
• Connecting cables should be connected to the leads as follows:
Pump with three-phase current motor (3~400V):
For the three-phase current connection (DM), the leads of the
free cable end are to be assigned as follows:
Mini SDL: 6-lead connection cable 6x1.0 mm²
Lead no. Binder
1 U
2 V
3 W
green/yellow PE
4 T1 (WSK)
5 T2 (WSK)
The free cable end is to be wired up in the switch box (see
switch box Installation and Operating Instructions).
