TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the
connection diagram label on the unit side.
Do not interconnect negative sides of input and output
terminals (via grounding terminals e.g.) as they are not of the
same potential level.
Ground the terminal 6 for RFI protection if necessary. When
grounded, dielectric strength between output signal line and
ground is of 50V DC, though it is of 500V AC when not
grounded.
