2.2 Connection to power
– Note information given on the instrument data plate (voltage, frequency)!
– Electrical connection in conformity with IEC 364 or equivalent national standard.
Special regulations apply to installation in hazardous areas. Please refer to separate "Ex"
installation instructions.
– The PE protective ground conductor must be connected to the separate U-clamp
terminal in the terminal box of the signal converter.
– Do not cross or loop the cables in the terminal box of the signal converter. Use separate
(PG or NPT) cable glands for power and output cables.
– Ensure that the screw thread of the round cover on the terminal box is well greased at all
times.
NOTE: The grease used must be non-corrosive to aluminium; typically it must be resin- and
acid-free.
– Protect sealing ring from damage.
