Wiring of main circuit (FR-HC2-7.5K to 75K, FR-HC2-H7.5K to H220K)
(8) Wiring of outside box and high power factor converter
Use the cable shown in the below table for the connection.
Converter terminals ROH and SD are used for the control signal for the inrush current limit circuit inside the outside box.
Always connect them to the outside box. Failure to do so will cause internal circuit breakage of the outside box.
Connect the output from the MC start command terminals (88R, 88S) to the terminals (88R, 88S) of the outside box.
<Wiring example of 7.5K>
The terminal arrangement in the outside box differs by capacity. Check the terminal arrangement on 6.3 Outline dimensions (refer to page 150).
