Notes:
1. Terminals (Q and (_ are normally open contact. They are different from terminals
(_ and (_) (normally closed contacts) of the previous types (CPCR-MR01 to -MR05).
2. Thermal overload relay is directly connected to terminal (_ and the motor in series. Pre-
vious types (CPCR-MR01 to -MR05) have connection terminal (_.
3. Terminal (_ is not connected internally. In the previous types (CPCR-MR01 to -MR05)
it is common to SG 0V.
4. O.S drive works only for type CPCR-MR_._CJ.
