Page 17: Drive Dimensions
Figure 3-1 Fire enclosure bottom layout Drive The bottom, including the part of the side considered to be part of the bottom, must be designed to prevent escape of burning material - either by having no openings or by having a baffle construction. This means that openings for cables etc. must be sealed with materials meeting the 5VB requirement, or else have a baffle above. - Page 18 Figure 3-3 Dimensions 47mm 7.5mm 226mm (8.9in) (1.85in) (0.3in) 220mm (8.66in) 249.7mm 322mm 292mm 304mm (9.83in) (12.68in) (11.49in) (11.96in) 226mm (8.9in) ∅5.4mm (0.21in) 229mm (9.02in) 62mm (0.24in) (2.44in) Figure 3-4 Ingress protective label Ingress protective labels The ingress protective labels (shown on Figure 3-4 above) should remain in place while NOTE the drive is mounted, and until all the electrical wires have been connected.

Page 25: Electrical Installation
If the drive has failed in a manner that causes the display to go blank immediately, it is possible the capacitors will not be discharged. In this case, consult Nidec Industrial Automation or their authorized distributor. Equipment supplied by plug and socket Special attention must be given if the drive is installed in equipment which is connected to the AC supply by a plug and socket. -
Page 26: Supply Types
Permanent magnet motors Permanent magnet motors generate electrical power if they are rotated, even when the supply to the drive is disconnected. If that happens then the drive will become energized through its motor terminals. WARNING If the motor load is capable of rotating the motor when the supply is disconnected, then the motor must be isolated from the drive before gaining access to any live parts. -

Page 29: Ground Connections
An MCB (miniature circuit breaker) may be used in place of fuses under the following conditions: • The fault-clearing capacity must be sufficient for the installation • The I T rating of the MCB must be less than or equal to that of the fuse rating listed above For a parallel DC bus system the maximum AC input fusing is shown in Table 4-2 below. -
Page 30: Ground Leakage
Ground leakage The ground leakage current depends upon whether the internal EMC filter is installed. The drive is supplied with the filter installed. Instructions for removing the internal filter are given in Figure 4-3. With the internal EMC filter fitted the ground leakage current is as follows: Table 4-3 Ground leakage current with internal EMC filter installed 3 phase Star 3 phase Delta... - Page 31 the second environment. For longer motor cables, the filter continues to provide a useful reduction in emission level, and when used with any length of shielded cable up to the limit for the drive, it is unlikely that nearby industrial equipment will be disturbed. It is recommended that the filter be used in all applications unless the ground leakage current is unacceptable or the above conditions are true.
