Information
Information about AP418i connection boards:
When laying transducer cables outside of enclosed areas or with cable
lengths greater than 30 m between the connection board and transducer,
the sensor cables must be designed with an additional, separately grounded
shield to ensure overvoltage protection. This can be done for example by
laying the cable in a metallic pipe or using double-shielded cable, in which
case the outer shield must be connected to ground potential or protective
conductor potential where it is close to the connection board (for example
where it enters the switch cabinet). HBM recommends Triaxial cable for this
purpose.
