UFor direct wallmounting,we advise using thedowels supplied (S253.5x25 screws)ormeta + a l

panel. In this latter case, use the M3x10screws suppliedinthe fixingkit .

UThe cables carryingthe signal shouldnot be thousedcloseto thepower supply cables or the contac

cables

UAt the minimum, the main insulation should be provided against thecontrol powersupply syste m

to which theprobe is connecte d
