Installing The Built-In Style; Electrical Connections - Bühler technologies CPsingle Manual De Instrucciones

CPsingle, CPdouble
The unit is intended for use in enclosed areas. Adequate pro-
tection from the weather must be provided when used out-
doors.
Pump models for the USA and Canada 4492***1*** in non-
explosive areas
The peristaltic pumps must be installed inside a housing
which requires a tool to open and meets the requirements of
the overall installation with respect to the housing, layout,
space requirement and condensate separation.
Select a housing which meets the requirements of the pump's
intended use with respect to mounting, spacing and creepage
paths. The housing must be suitable for operating temperat-
ures of 0 °C to min. 52 °C.
It must be fully wired inside the housing. The cables and ter-
minals used must be US-listed or (if applicable) CSA certified.
They must be designed for the nominal voltage, the nominal
current and an operating temperature range of 0 °C to 52 °C.
Water and contaminants must be prevented from entering
the unit.
4.2 Mounting
WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
There are two holes at the bottom of the mounting bracket.
These can be used for screws.
Connect the tubes to the connectors and assure they are close.
The pump direction is given on the cover.

4.2.1 Installing the built-in style

The built-in style (without housing) of the CPsingle is de-
livered pre-assembled. Proceed as follows to install:
Prepare the mounting
plate for the pump. The
locations of the bores are
indicated in the adjacent
drawing. The mounting
plate must not be thicker
than 3 mm.

Remove the two hex nuts
and insert the drive motor
including retaining plate
and pressfit stubs into the
prepared coupler from the
back.
Tighten the hex nuts M3.
Attach the pump head
bracket (3) to the gear axle.
Insert the rotor (4) – cyl-
indrical neck forward - into
the pump head bracket,
now slide the entire as-
sembly onto the gear axle
and the retaining bolts.
Tighten (1) knurled nuts.
Insert the hose fitting (5)
with hose into the square
breakouts.
Finally, attach the hood (6)
and secure with the
knurled nut.

4.3 Electrical connections

4.3.1 Electrical Connections (housing version / 115 V or
230 V)
Make sure that mains voltage and frequency meet the spe-
cifications of the motor (voltage tolerance ± 5 % and fre-
quencytolerance ± 2%.)
Peristaltic pumps of housing version type SA-AC (230/115 V)
are delivered as standard with a 2 m connecting cable.
The fixed connection cable for the housing version has three
numbered braids and one PE connection.
