Print Date Manual Number Revision 12/2006 pdp-dk 192716 First edition For Maximum Safety Mitsubishi transistorized inverters are not designed or manufactured to be used in equipment or systems in situations that can affect or endanger human life. When considering this product for operation in special applications such as machinery or systems used in passenger transportation, medical, aerospace, atomic power, electric power, or submarine repeating applications, please contact your nearest Mitsubishi sales representative.
This section is specifically about safety matters Do not attempt to install, operate, maintain or inspect the inverter until you have read through this Installation Guideline and appended documents carefully and can use the equipment correctly. Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions.
Wiring CAUTION Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained Test operation and adjustment CAUTION...
The internal filter is suitable for the second environment, a motor cable length of up to 5m and a carrier frequency of up to 2kHz. For other operation conditions, Mitsubishi Electric offers several optional filters. Please contact your sales representive.

WIRING 3.2 Wiring fundamentals 3.2.1 Cable size Select the recommended cable size to ensure that a voltage drop will be 2% max. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency.

WIRING 3.2.2 Maximum permissible motor wiring length The maximum permissible length of the motor cables depends on the capacity of the inverter and the selected carrier frequency. (The wiring lenght should be 100 m maximum with vector control). The lengths in the following table are for unshielded cables. When shielded cables are use divide the values listed in the table by 2.
3.3 Control circuit terminals 3.3.1 Terminal layout CA SD PC STOP RES STF STR PC FU MRS JOG CS 3.3.2 Instructions for wiring of the control circuit terminal Terminals PC, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Avoid connecting the terminal PC and 5 and the terminal SE and 5 (ground).
