2.1 Current measurement

When installing the current converter, care should be taken to ensure
that the load current flows through it. The outputs of the compensation
network must be installed behind the current converter (in the
direction of current flow). If the BR 604 is connected up via sum-
current converters, the overall conversion ratio is entered.

Example:
C.converter 1: 1000/5A
C.converter 2: 1000/5A
Sum-current converter: 5A+5A/5A

C.converter ratio is: 2000/5A
