7.2.4 Preparing the measuring device
Carry out the steps in the following order:
1. Mount the sensor and transmitter.
2. Sensor connection housing: Connect sensor cable.
3. Transmitter: Connect sensor cable.
4. Transmitter: Connect cable for supply voltage.
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 →  45.

L
WARNING
Risk of electric shock! Components carry dangerous voltages!
‣
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.
‣
Observe grounding concept of the plant.
‣
Never mount or wire the measuring device while it is connected to the supply voltage.
‣
Before the supply voltage is applied, connect the protective ground to the measuring
device.
