Equipotential terminals

The terminals are designed to be used in domestic and industrial distributions electrical panels as terminal boards for main bonding. EPS 1 and EPS 2 are supplied either with cover (with sealing option) or without cover. EPS 3 is supplied without cover and in the version EPS 3+KO 100E (in addition to EPS 3, the delivery also includes the installation box, KO 100E, with cover and connecting material for the installation of the terminal board in the box). The terminal board can be attached using M 5 screws (not included in the delivery) on the wall, on the distribution panel etc. The fastening screws are not conductively insulated from the terminal board bridge. The terminal board without cover can also be installed in the installation box (we recommend KO 125E and KT 250L for EPS 1
and EPS 2, and KO 100E for EPS 3).
The equipotential terminals comply with the requirements of standards CSN EN 60998-1:05 ed. 2, CSN EN 60998-2-1:05 ed. 2, CSN EN 60947-1:08 ed. 4 and CSN EN 60974-7-1:03 ed. 2.

The EPS 4 equipotential terminals are used for main bonding – balancing the potential, in compliance with CSN 33 2000-4-41 and as an equipotential terminal in compliance with CSN EN 62 561-1.
FeZn grounding conductors have to be straightened and shaped prior to connection under the conditions of EPS 4 terminal installation. The conductors must not be "tightly stretched" so that the terminal could be pulled out from the TH rail, or the panel (for example from TH 35 rail in KT 250 built in the wall of the object). In applications when it is not possible to avoid stretching conductors, it is recommended to use plastic zip ties to secure EPS 4 on the TH 35 bar (the zip tie is threaded through the corners of EPS 4 that are primarily designed for panel installation screws). Furthermore, conductors have to be cleaned from surface corrosion and impurities that may settle on the conductors during installation (paint etc.).
