Note 1. For the MR-RB138-4. For the MR-RB138-4, three units are used as one set (permissible wattage: 3900W).
2. When using the Power factor improving DC reactor, disconnect the short bar across P
1-P2.
3. Make up a sequence that turns off the drive unit forced stop (EM1) and the converter unit forced stop (EM1) at the same time.
4. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class.
5. Attach connector for magnetic contactor wiring on the converter unit. Unattached state may cause an electric shock.
6. For specifications of cooling fan power supply, refer to section 13.3.8.

13.3.4 How to use the connection bars
Make sure to use the supplied connection conductors and connect the L
and L of the drive unit to those of
the converter unit as shown below. Never use connection conductors other than the ones supplied with the
drive unit. Both units are shown without the front covers.
