Any type of soiling (dust, humidity etc.) will negatively affect the operation of the system over the desired period of use. This applies particularly for the usability of the seals and crimping of the contacts. The utmost care must therefore be taken to work cleanly during installation.

Different circular contacts are used for different conductor cross-sections for the TYCO SOLARLOK connectors. The correct tool insert must be used, depending on this cross-section. The enclosed TYCO SOLARLOK connectors are equipped with circular contacts for a cable cross-section of 4 mm. The enclosed seals have internal dimensions of 6 (for cables of 5.3 to 6.2 mm sheath diameter) and 8 mm (for

cables of 7.2 to 8.0 mm sheath diameter). The seal must be matched to the sheath diameter of the cables used.

The following sequence must be observed for assembly of TYCO SOLARLOK connec- tors:

1.

Strip the voltage-free cable by 8 mm.

 

2.

Crimp on the circular contact.

EN

 

3.Push the cable gland, clamping piece and seal onto the cable.

4.Engage the contact in the connector housing.

5.Screw on the clamping nut.

6.Tightening torque of the threaded cable gland is 1.5 Nm.
