6.5 Make Crimp Connections
The connection of the crimp contacts has to be made
according to DIN EN 60352-2 – Solderless Connections.
In order to comply with DIN EN IEC 61984 make sure that
always the live side of the connector – no matter wheth-
er plug or receptacle – is tted with socket contacts.
For all contact inserts observe the following:
- for pin inserts a socket contact must be used for the
protective earthing (PE) contact,
- for socket inserts a pin contact must be used for the
protective earthing (PE) contact.
Assembly
X Disengage the cable at the connection end from
the coating and strip cable strands approx. 7 mm.
X Push the cable strands into the contacts.
X Crimp the cable strands to the contacts using the
crimping pliers.
- In doing so, observe connection cross-section
of contacts depending on the model of the
crimp contacts (refer to section “6.2 Crimp con-
tacts (pin / socket) and ller plugs”).
- Crimping must be made in the centre between
the sight drill hole and the end of the contact.
