General information
Connectors may not be connected or disconnected under load. The
temperature range for connectors can be found in the catalog data. The
degree of contamination is given in the technical data of the connector.
The rated voltage and rated current are based on a power system with
DC or AC (rms) at a frequency of 50 or 60 Hz at 0 ... 2000 m above sea
level, and are given in the technical data of the connector. For other
applications, the additional loads (e.g. electrical, chemical, climatic,
biological, mechanical or radioactive) can mean for the connector, or
request mateability with competitive products the user is responsible
for the review and approval.
Connectors
Connectors are devices that are not for connection or disconnection
under load.
Application Note: This distinguishes these kind of connectors from
plug devices that may be connected or disconnected under load. When
connecting or disconnecting a connector under load, sparks and at
short-term high temperatures that can cause damage to the contact
surface and finally a total failure of the connector.
Types of connection
For EPIC® Industrial Connectors different connection types of wire to
the electrical contact are available. There is the classic screw, crimping,
soldering and the spring-loaded terminals and Push-In.
Application Note: Each of these connection types has advantages and
disadvantages. Screw is the simplest and a very common practice.
Crimping gives with the appropriate crimping tool 100% process-reliable
results, but it requires special tools. Spring loaded terminals also allows
quick and easy connection and is vibration resistant. Soldering requires
little space and is often used with small connector systems. Push-In is
ideal for massive conductors and cores with wire end sleeves.
Rated voltage
The rated voltage is the voltage according to which the connectors are
designed and related to the relevant operating characteristics.
Application Note: The rated voltage is defined depending on the envi-
ronmental degree of contamination for which the connector it is devel-
oped and tested. If the same connector is tested for pollution degree 1,
the rated voltage given in the catalogue is significantly higher than
when he was tested for pollution degree 2. EPIC ® connectors are gener-
ally designed for pollution degree 3 and therefore have high safety
reserves, even if the plug moist inside or should be dirty.
Rated current
A current value assigned by the manufacturer, which the connector or
PSD can carry continuously (without interruption) and simultaneously
through all its contacts wired with the largest conductor preferrably at
an ambient temperature of 40°C without the upper temperature being
exceeded. The rated current is specified for the largest conductor
cross-section.
Rated impulse withstand voltage
The test voltage is the maximum voltage at which a connector will not
be subjected to flashover under the set conditions.
Application Note: In this specified voltage there will be no spark
damage to the connector.
EMC (electromagnetic compatibility)
The capacity of an electrical installation to function satisfactorily in its
electromagnetic environment without an unacceptable influence to the
environment which also includes other installations (DIN/VDE 0870,
Section1).
Application Note: For good EMC shielding, there is a diagram that
describes the behavior for different frequencies. This serves as an
evaluation criterion to compare different components. In the industrial
sector, the interfering frequencies are in the lower frequency range.
Typically less than 100kHz. In this frequency range, it depends mainly
on a low impedance, high crosssection, 360° shielding. When evalu-
ating the different EMC concepts such qualitative parameters can be
recognized easily. The EPIC® ULTRA housing convinces with a highly
sophisticated sealing and contact technology. The innovative design
allows safe EMC contact and allows the current on the cable screen
to flow to the ground. The 360° shield connection is done via the cable
gland SKINTOP® BRUSH.
Coding
Coding is a system by which it is possible to prevent interfacing confu-
sion between adjacent connectors which are of the same configuration.
This is useful if two or more connectors of the same type are mounted
on the same unit
Application Note: So plugging errors and incorrect wiring is prevented.
When coding the rectangular connector with guide pin and guide
bushing in addition the plug insert is centered. Uncentred connection
is prevented resulting in an increased service life of the contacts. For
every EPIC® connectors exists the right coding element.
