1) Overvoltage category III: Equipment intended for the use in installations or parts of it in which lightning overvoltages do not need to be
considered, however switching overvoltages generated by the equipment, and for cases where the reliability and the availability of the equipment
or its dependent circuits are subject to special requirements. Examples are protecting means, switches and sockets.
2) Pollution degree 3: Conductive pollution occurs or dry non-conductive pollution occurs which becomes conductive due to condensation
which is to be expected.
Remarks
Safety classification
1. General Remarks
These connectors are designed and produced in conformity with
the low voltage directive (73/23/EWG) respectively Geräte-
sicherheitsgesetz (German law) and are especially in according
with the standards DIN EN 61984 / IEC 61984 (VDE 0627);
IEC 60664-1 (VSE 0110-1) and IEC 60529. The connectors may
be used only within the technical ratings. These connectors with /
without breaking capacity are designed and produced according
to DIN EN 61984/VDE0627.
All technical data refers to mated connectors under live
conditions. The safety of the connector system depends on the
correct selection of products, proper assembly of the connector
device, and a precise fit of the connectors.
2. Application Remarks
Connectors with / without breaking capacity must be used
according to specified technical ratings.
The technical data represents the initial value of mated parts
under predetermined conditions and length of time. These
values could change with different test parameters or product
requirements.
The 16-3 Series connectors are used in a wide variety of industries
and equipment. Some of these include industrial machines and
controls, data processing, instrumentation and test equipment,
medical devices, telecommunication’s network and equipment,
plus outdoor and marine applications.
All rated data for the connectors listed in this catalogues are
based on over-voltage category III 1) and pollution degree 3 2) for
electronic applications.
Connectors were completely mated according to their respective
safety locking mechanism. Selection and testing of connectors with
/ without breaking capacity to meet specific product or industrial
requirements such as rated voltage and the related clearances and
creepage distances are the responsibility of the user.
3. Assembling Remarks
Protection against electrical shock of the termination of the
connectors shall be secured by correct mounting. Connectors of
the same or different series being mounted side by side may be
protected against incorrect mating by the use of coding options.
Care must be taken to ensure the parts are correctly mated and
screws are tightened with the proper torque.
4. Termination Remarks
Cable connectors are effectively secured when using the internal
cable clamp. When the connector contains a simple gland bushing for
retention without clamping ring the cable should have a strain relief
close behind the connector. All cable properties or specifications
must be compatible with the connector design and materials.
Designated wire conductors must be terminated to the correct poles
in the connector.
Crimp contacts must be fully inserted into the plastic housing and
retention assured with a slight tug on the wire.
Wire should be stripped correctly according to printed specifications
to insure no electrical contact can be made between the conductors.
There should be no nicked or cut strains during the stripping action.
