Connectors are here seen from the front side which is the
mating face. The orientations of the contact blocks to the arc-shaped
guides are shown in section P of our general catalogue, but always from
the wiring side. The following rules are only valid for standard versions.
Other orientations of guides and/or guide marks may exist as special options.
All connector types “A” and “Z” for D-hole mounting per Type 2 have the arc-shaped guide on the left side when the mounting flat is in the 12 o’clock position. A standard connector mounted in this hole will have its guide mark at the 12 o’clock position.
All connector types “A” and “Z” for double D-hole mounting per Type 3 have the arc-shaped guide oriented in parallel to the two flats. A standard connector mounted in its hole will have its guide
mark at the 12 o’clock position when the arc-shaped guide is
placed to the left side of the connectors.
