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 protection from the weather must be provided when used outdoors.
The pressurised encapsulation must be protected from sunlight 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 cable (at least 4 mm
2
) via the earthing terminal on the terminal box
or the fixed and the secured metal contact between the motor and machine which in turn is connected with the potential equal-
isation system of the machine (EN 60079-14:2014).
To protect the motor against short-circuits we recommend using 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.
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
2
) must be connected 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.
