1. First, make a required number of holes in the seal, then route the cable through the rack, seal and swivel nut as in the figure. Maximum 200 mm of cable can overlap the ring edge. Fasten the rack with U-bolt (not included in the package).
2. Install the seal with cables in the rack slot, install the nozzle and fix with swivel nut.
3. Install enclosure at the rack, line the gasket and fasten the enclosure with M42 nut.
4. Perform wire routing and ground cable armors.
5. Route the power cable through cable gland VK-VEL-M32. The second cable gland VK-VEL-M32 is closed with plug; if necessary, remove the plug and connect transit cable.
6. Close the box cover.
