(BASED ON DIN EN 175301-803)
Dear Customer,
To ensure the function of the product as well as your own safety please read carefully the manual before
starting the installation of the product.
In general
HAFNER Pneumatik does not accept any liability if the regulations of this operating instruction are not
followed, and for repairs resulting from incorrect use of the connectors. This includes the liability of products
as well accessory items. Make sure to obey the instructions given in this manual as well as the required
environmental conditions published in sales literature as well as on the internet and on labels printed onto
the products. When selecting, installing or operating the product, please obey the general rules of
technology. Make sure to avoid unintended activation as well as any kind of improper use.
Caution! Risk of injury! The electrical connector’s surface can get hot during continuous
operation.
The operating instructions apply to the following electrical connectors:
ST 30 DIN IP65
ST 30
ST 22 M
ST 223 24
ST 222 V 230
ST 302 V 24
ST 22 E 4-6
ST 222 V 24 P E 1 N
ST 222 V 24
ST 302 V 230
ST 22 E 1 N
ST 222 V 24 J
ST 222 V 110
Some electrical connectors are wired and have a LED that illuminates when under voltage and a varistor
that protects the controller from solenoid surges.
Installation
The relevant regulations must be observed during installation, maintenance or repair. Electrical installation
must be carried out by or under the supervision of a qualified electrician, taking into account the relevant
international standards.

Connecting the connectors
Wire ends have to be stripped to a maximum of 5,5mm (7/32 inch) to control the depth of the wire into
the contact. (Wire end sleeves are recommended.)
After stripping the wires, the order of connecting the positive and negative poles can be reversed. When
using alternating current (AC), the earth must also be connected to the contact marked with a symbol on
the connector surface:
Intended use
The connectors are only used for connections between components, devices and systems, for the
transmission of electrical energy and signals.
Make sure that the connectors or sockets are always provided with plug contacts on the live side.
Ensure that the connecting cables are not subjected to unacceptable tensile, compressive, bending or
torsional loads.
Only work with people who meet the specified requirements when working on the connectors.
Connectors must not be connected or disconnected under electrical voltage.
Protect the mounting location of the connector from light.
The use of a flat seal for the electrical connections during assembly is mandatory.

After connecting the electrical connector, tighten the retaining screw to the correct torque.
If a problem is detected when connecting to the socket (e.g. dirt, bent contacts etc.), the cause must be
rectified.
During operation, make sure that the maximum permissible temperature at the connection is not exceeded.
Defective devices cannot be repaired.
The cable connections must be free of dirt and corrosion.
It is forbidden to unplug or forcibly insert the plug from the power supply.
Protect electrical connectors from dirt, aggressive substances (e.g. acids, alkalis, gases etc.), moisture and
from not allowed temperatures.
The connectors must be cleaned regularly. Use an antistatic cloth for cleaning. Disconnect from the power
supply before cleaning.
