Assembly instructions
1. Strip cable to 23+2 mm.
2. Push conductor through the cable gland and the
housing. Push the stripped end of the conductor
into the termination entry of the module until the
insulation touches the contact.
3. To tighten the axial screw, a hexagonal wrench
size 8 is needed. Insert the hexagonal wrench on
the mating side of the contact. At the same time,
push the conductor over the axial screw.The lo-
cking screw has to be tightened with the recom-
mended tightening torque that is determined by
the conductor’s cross section.
4. Once the modules are terminated, they are
mounted into the housing by using two metal fra-
mes (tightening torque of the fixing screws = 0.5
Nm). The modules have 4 pegs formed by 2 par-
allel ribs (each peg shapes like a “H”). Each rib
takes 1 pole frame, where the lateral link has to go
into the relief of the frame. The 2 pole frames have
2 cutouts on the wall which get fitted to the “H”-
shaped pegs (see figure). The heads of the screws
have to face the mating direction of the module.
Coding can be established by rotating the contact
by 90 degrees. Therefore it is important that the
corresponding modules are assembled in the cor-
rect position otherwise mating is not possible.
5. After assembling the modules in the housing,
the tightening torque of the locking screw can be
checked and corrected if necessary.
6. After final assembly of the contacts, the user
should ensure that the cable is adequately
strain reliefed to protect the contact from ra-
dial stress.
