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 knurled nuts M3
(1) at both ends.
Pull the entire pump head
off the gear axle with a slight
back and forth motion.
You will see two hex nuts M3
(2).
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 assembly
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)
Verify the pump motor has the correct voltage and frequency
(voltage tolerance ± 5 % and frequency tolerance ± 2%).
Peristaltic pumps housing style type SA-AC (230/115 V) come
standard with a 2 m connecting cable.
The fixed connection cable for the housing version has three
numbered braids and one PE connection.
Connect the protective conductor to the yellow/green
wire of the connecting cable.
The supply line and earthing cross-sections must be aligned
with the rated current.
Use a minimum line cross-section of 0.5 mm
connection and particularly the protective earth.
Be sure to observe any varying information in the rating plate.
The conditions at the site must correspond with all rating
plate information.
When connecting to a 115 V or 230 V supply, connect the fol-
lowing braids:
