6.2.3 Terminal assignment
Transmitter: supply voltage, input/outputs
The terminal assignment of the inputs and outputs depends on the individual order
version of the device. The device-specific terminal assignment is documented on an
adhesive label in the terminal cover.
Supply voltage Input/output 1 Input/output 2 Input/output 3
1 (+) 2 (–) 26 (+) 27 (–) 24 (+) 25 (–) 22 (+) 23 (–)
Device-specific terminal assignment: adhesive label in terminal cover.
Terminal assignment of the remote display and operating module → 39.
6.2.4 Preparing the measuring device
NOTICE
Insufficient sealing of the housing!
Operational reliability of the measuring device could be compromised.
‣
Use suitable cable glands corresponding to the degree of protection.
1. Remove dummy plug if present.
2. If the measuring device is supplied without cable glands:
Provide suitable cable gland for corresponding connecting cable.
3. If the measuring device is supplied with cable glands:
Observe requirements for connecting cables → 33.
6.3 Connecting the measuring device
NOTICE
Limitation of electrical safety due to incorrect connection!
‣
Have electrical connection work carried out by appropriately trained specialists only.
‣
Observe applicable federal/national installation codes and regulations.
‣
Comply with local workplace safety regulations.
‣
Always connect the protective ground cable before connecting additional cables.
‣
For use in potentially explosive atmospheres, observe the information in the device-
specific Ex documentation.
