2.4 Operational safety
‣Prior to commissioning the entire measuring point, check that all connections are correct.
Ensure that electrical cables and hose connections are not damaged.
‣Do not operate damaged products, and secure them against unintentional commissioning.
Label and identify the damaged product as being defective.
‣If faults cannot be rectified, the products must be taken out of service and secured against
unintentional commissioning.
CAUTION
!
The cleaning system is not switched off during calibration or maintenance activities
Risk of injury due to medium or cleaning agent
‣If a cleaning system is connected, switch it off before removing a sensor from the medium.
‣If you are not switching off the cleaning system because you wish to test the cleaning
function, wear protective clothing, goggles and gloves or take other appropriate measures.
2.5 Product safety
2.5.1 State of the art
The transmitter is designed to meet state-of-the-art safety requirements, has been tested and
left the factory in a condition in which it is safe to operate.
Relevant regulations and European standards have been observed.
2.5.2 IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings.
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.
Support in the performance of this task can be requested from Endress+Hauser.

• Inputs are assigned to measuring channels in
ascending order of the slots and ports.
Adjacent example:
If "CH1: 1:1 pH glass" is displayed, this means:
Channel 1 (CH1) is slot 1 (base module) : port 1
(input 1), pH glass sensor
• The outputs and relays are named after their
function, e.g. "Current output", and are displayed with
the slot and port numbers in ascending order
