  • Page 17: Installation And Connection

    Do not install the drive upside down, or horizontally. Heat is generated while the drive is operating, so the open- ings shown in Figure 2-2-1 are necessary for the passage of VM10 cooling air. The generated heat is convected upward by the Drive 0.4"...

  • Page 18: Connection

    ° If two or more drives need to be installed in the same device or control panel, they should be ar- ranged horizontally to minimize the influence of heat between them. If two or more drives must be installed vertically, place a plate between them to prevent the upper drive from being affected by heat from the lower drive.

  • Page 19: Connecting The Main Circuit And Ground Terminals

    For single phase 230V input circuit breaker which can also detect DC current is rec- ommended. Phase-sequence matching is unnecessary. VM10 It is recommended that a magnetic contactor is con- nected to prevent any failure or accident from becoming P(+)

    13-2 RFI Filters It is strongly recommended that the appropriate VM10 input filter is used, as shown in the following table, to limit RF current flowing into the main supply circuit. Without an input filter a VM10 installation may not meet statutory requirement. The drives contain high-power semi-conductor devices which are switched at high speeds to synthesize a near-sinusoidal current wave form across the frequency range of output.

Remark : To minimize the conducted radio disturbance in the power distribution system, the length of motor cable should be as short as possible. And it is user's responsibility to confirm that the apparatus, which the Drives in- stalled in, conforms to EMC directive when longer motor cable is used or other installation conditions are differ- ent from those described in this manual.

    13-3 Electromagnetic Compatibility (EMC) Recommended Installation Instructions It is necessary that thes e instructions be followed to conform to EMC Directives. Follow the usual safety procedures when working with electrical equipment. All electrical connec- tions to the filter, Drive and motor must be made by a qualified electrical technician.(Refer to Fig. 13-3-1 and Fig.
