Operation under difficult conditions, in particular on ships, requires additional
measures to be taken for correct installation, depending on the operating location.
Further information and instructions on this can be obtained from your regional sales
contact upon request.
IP30 coverings included in the delivery must be used for non-used ports/interfaces
(RJ45/USB). Exception: RS485.
