General Information
1.1
Important Safety Instructions for operating Coriolis Flowmeters
The RHE26 and RHE27 transmitter models are designed to be installed through a control
panel or enclosure door so that the terminals on the rear are protected from water and
moisture ingress. The front panels of the RHE26 and RHE27 provide a protection class
of IP20. They are not suitable for installation in wash down or other “wet” areas.
For RHE26 and RHE27 units requiring 12 to 24V DC power, the use of a properly
grounded (PELV) supply is highly recommended.
The use of shielded cables for all I/O signals is recommended to prevent interference
from high level EMI.
Only the specifically designed shielded cable supplied by Rheonik should be used to
connect RHE Transmitters to RHM Flow Sensors. Do not use other types of cable.
For safety instructions regarding RHM Coriolis Flow Sensors, please refer to the RHM
installation and startup guide manual.
These measuring instruments are not designed for, and should not be installed in, life-
preserving systems used in the medical, motor vehicle, aircraft, water craft or mining
industries.
All national regulations and standards regarding electrical installation must be
observed!
