3 Transport and storage
The products should be transported only in its original pack-
aging or a suitable replacement.
When not in use, protect the equipment against moisture and
heat. Keep it in a covered, dry and dust-free room.
4 Installation and connection

4.1 Installation site requirements

Be sure to maintain the approved ambient temperature.
Please also note the technical data of the add-on gas cooler.
When mounting to a subframe, it screws directly onto the
cooler housing frame.
The unit is intended for use in enclosed areas. Adequate pro-
tection from the weather must be provided when used out-
doors.
The pressurised encapsulation must be protected from sun-
light to prevent prohibited heating.
The ambient temperature is 0 °C to +60 °C.
The minimum bend radius of the connecting cable is 55 mm.
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.
The adapter plate has two bores each at the top and bottom.
These are used to screw down the device.
Slide the hoses over the connection fittings, secure with a
hose clamp or nut, and ensure the connection is tight.

4.3 Electrical connections

Compare the mains voltage with the specifications in the
name plate of the motor, not exceeding max. ±5 % from the
operating voltage specified. The mains voltage specified must
not deviate from the operating frequency by more than ±2 %.
(Range A per EN 60034 + Cor.:2010)
The external potential equalisation must be established via
2
cable (at least 4 mm ) via the earthing terminal on the ter-
minal box or the fixed and the secured metal contact between
the motor and machine which in turn is connected with the
potential equalisation system of the machine
(EN 60079-14:2014).
To protect the motor against short-circuits we recommend us-
ing one of the following devices:
• Fuse per IEC 60127,
• 2-pole automatic fuse,
• 2-pole protective motor switch.
The recommended rated current is between 0.5 A and 1.6 A,
the breaking capacity must be appropriate for the conditions
on site, at least 1500 A.
6 Bühler Technologies GmbH
We recommend one of the following devices as separator, also
in all-pole version:
• automatic fuse,
• protective motor switch
• 2-pole relay with positive-action contacts.
Per EN 60204-1 the motor must not be overloaded; external
overload protection may be omitted.
Peristaltic pumps type SA-AC-X1 (230 V AC 50/60 Hz and
115 V AC 50/60 Hz) come standard with a 3 m connection
cable.
Motor direction of rotation: CV (clockwise rotation).
The fixed connection cable has three strands: N+L and one PE
connection.
The protective conductor (at least 4 mm
nected to the yellow/green strand of the connection cable.
When connecting the non-terminated cable end of the motor
to a circuit within the explosive area, select a terminal box
with separate certificate and explosion markings per the on-
site conditions.
Be sure to observe any varying information in the rating plate.
The conditions at the site must correspond with all rating
plate information.
Protective measures against prohibited heating
Unless otherwise certified, the electric motor may only be
used for continuous operation, not frequent restarting
without significant start-up warming.
5 Operation and control
NOTICE
The device must not be operated beyond its specifications.
The pump does not have a power switch. It starts running as
soon as the power supply is turned on.
NOTICE
Installing peristaltic pumps CPsingle / CPdouble limits the
maximum permissible operating pressure in the system!
Operating pressure ≤ 1 bar
6 Maintenance
