Notes: 1. One unit of cooling fan is attached for MR-RB137-4 and MR-RB13V-4. 2. Three units of MR-RB137 or MR-RB13V-4 are required per resistance regeneration converter unit. 3. Connect the regenerative option to the resistance regeneration converter unit, and keep the total length of the wiring within 5 m. 4. Disconnect a short-circuit bar between P1 and P2 when using the power factor improving DC reactor.
