- equipped with metal lead - in couplings VM for metal hoses brands MRPI, MRN, RZ - Ts, RZ - TsKh:
- VM - 15 coupling with ½ "lead - in thread (nominal bore of metal hose 15 mm)
- VM - 20 coupling with ¾ "lead - in thread (nominal bore of metal hose 20 mm)
The installation dimensions of the connecting device are given in Appendix A.
A printed circuit board is installed inside the product body, on which there are screw terminal blocks for connecting the connected conductors.
Placement and installation
- Unscrew the cover fixing screws, remove the cover.
- Check that the cable glands are securely fastened and ensure that the rubber seals are present.
- Feed the cable through the cable gland. Fasten securely inside the cable gland. To ensure a tight seal, the cable gland O - ring must be tightly fastened. Free the insulated cable cores from the outer insulation and cut the ends of the inner insulation to a length of 5..8 mm. Connect the cable conductors to the terminals of the terminal block. Put on the cover, tighten the fastening bolts.
- After installation, seal the cover fixing screw (to be sealed by the installer).
