4. Disassemble the screw-in bushing and the clamping screws of the strain relief.
5. Ensure the correct seat of the seal insert in the double nipple.
6. Assemble the screw-in bushing (4) to the connection line and insert it through
the seal insert (3) and the double nipple (2) in the terminal box.
The outer sheath of the connection line must lie in the seal insert (3). Otherwise,
explosion protection and the IPprotection are no longer ensured.
7. Screw the screw-in bushing(4) to the double nipple(2) and tighten it securely
(hexagon nut, wrench size22). When tightening the screw-in bushing(4), the
solenoid coil must be supported in an appropriate manner or held up at the
double nipple(2) using an open-end wrench (wrench size46). The required
tightening torque depends on the line diameter.
8. Securely tighten the clamping screws of the strain relief (5).
9. Guide the individual conductor into the connection terminal and screw this into
place with the clamping screws.
Tightening torques for the clamping screws:
Table 11: Tightening torques
Operating voltage connection 0.4...0.5Nm
Connection for protective grounding conductor 1.0...1.2Nm
Connection for potential equalization conductor 2.0...2.4Nm
10. Assemble the cover with the sealing device underneath.
Tighten the mounting screws with their spring washers diagonally, one after the
other. Tightening torque of the cover screws: 1...1.1Nm.
