the PE at the RHM may occur. Connecting the shield to PE at both ends might lead to undesirable current flow in
the shield. In situations where a high potential difference is present between the RHE and RHM, we recommend
grounding via the PE C terminal on the RHM side.

Upon power up, if the RHE indicates an error and the temperature measurement on the bottom
right of the display shows “ -.--°C/°F ” please check the temperature measurement configuration
setting in the RHE (section 4.5).
The correct temperature measurement configuration setting for an RHM with connection type
JM or SM is “7”.

The shield of the cable is connected internally to the housing of the RHM. If there is a
risk of a significant potential difference between the housing of the RHM and the PE
terminal of the RHE, the shield should be connected to the RHE PE connection via a 1nF
capacitor. Alternatively, a separate cable can be run for potential equalization between
the RHM case and the RHE and the shield left both unconnected and isolated at the RHE
or terminated to the PE connection via a 1nF capacitor.
