3. WIRING
IMR02L04-E3
3-15
 Current transformer (CT) input/Feedback resistance (FBR) input
[optional]
 With CT input or FBR input, terminals 19 through 21 are allocated to the specified input.
 When using CT input, connect CTs to the relevant terminals.
CT: CTL-6-P-N [input range 0 to 30 A] (sold separately)
CTL-12-S56-10L-N [input range 0 to 100 A] (sold separately)
When CT type is not specified at ordering, the factory set value of the CT ratio is “800.” To use
CTL-12-S56-10L-N, change the set value of CT ratio into “1000” at the setting screen described below.
