If all the contacts are used, the S-EE series connectors may be used with voltages of up to 500V,
pollution degree 3, in accordance with the standard EN 61984.
If the number of contacts is reduced and the contacts accordingly assigned, these connectors may be used with
higher voltage. This is possible because the decrease in the number of contacts leads to an increase in
the surface distance in the air. When the contacts are arranged as shown below, the inserts may be used for
voltages up to 1000V, pollution degree 3, in accordance with standard EN 61984.
The S-EAV multipole connectors with incorporated terminal block are recommended for greater cost-saving and safety and are for machines, command and control panels use. For control panel mounting, bulkhead housings must be used.
This makes possible to maintain the IP66 degree of protection (in accordance with EN 60529) for coupled
housing-mounted connectors.
The S-EAV inserts are supplied in male or female versions and are mounted from the front of the enclosure or from the rear of the enclosure. The inserts can be mounted inside the control panels on DIN EN rails using suitable accessories providing the added advantage of easy sectioning.
The special structure of the S-EAV inserts have all the conductor connections on the same side allowing easier wiring and an unobstructed view of the work area.
The terminal block also has slots for housing the wire identification markers of each contact. Wire markers from different manufacturers may be used .
The S-EAV is available in left and right versions for mounting on the left or on the right of the control panel walls.
This characteristic is determined by the position of the contact "1" and the ground terminal in the upper part of the insert terminal block for both left and right mounting.
The installation of inserts on DIN rails inside the control panels is usually made to facilitate the wiring into sectionable parts. In this case the degree of protection for coupled connectors is IP 20.
This type of mounting requires supports to be provided to the inserts suitable for mounting on DIN EN 60715 rails.
In addition, female and male coupling screws are recommended for fixing the inserts to the enclosures in order to guarantee a stable and safe coupling between the S-EAV inserts installed on the DIN rails and corresponding S-E inserts.
