Calculation of the maximum load
Depending on the supply voltage of the power supply unit (U
S
), the maximum load (R
B
) including
line resistance must be observed to ensure adequate terminal voltage at the device. In doing so,
observe the minimum terminal voltage (

Preparing the measuring device
1. Remove dummy plug if present.
2.
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.
If measuring device is delivered without cable glands:
Provide suitable cable gland for corresponding connecting cable (
3. If measuring device is delivered with cable glands:

Connecting the measuring device
NOTICE
Limitation of electrical safety due to incorrect connection!
►
Have electrical connection work carried out by correspondingly trained specialists only.
►
Observe applicable federal/national installation codes and regulations.
►
Comply with local workplace safety regulations.
►
For use in potentially explosive atmospheres, observe the information in the device-specific Ex
documentation.
