3 Installation Promag 53 PROFIBUS-DP/-PA
32 Endress+Hauser
Assembly with ground disks (DN 15...300)
Depending on the application, e.g. with lined or ungrounded pipes (see Page 58 ff.), it
may be necessary to mount ground disks between the sensor and the pipe flange for
the potential equalisation:
Caution:
• In this case, when using ground disks (including seals) the total fitting length
increases! The dimensions plus information about the material can be found on
Page 155.
• PTFE and PFA lining → only install additional seals between the grounding disk and
pipe flange.
1. Place ground disks and seals between the instrument and the pipe flange (Fig. 19).
2. Insert the bolts through the flange holes. Tighten the nuts so that they are still loose.
3. Now rotate the grounding disk as shown in Fig. 19 until the handle strikes the bolts.
This will center the grounding disk correctly.
4. Now tighten the bolts to the required torque (see Page 34 ff.)
5. Connect the grounding disk to ground.
