Switching, disconnecting and protecting solution
To arrange the switching, disconnection and protection of the supply module, you
can use the following solution:
1. Equip the main circuit with a disconnecting device which meets the local safety
regulations.
2. The disconnecting device must separate the whole drive cabinet from the AC
power line, including the AC fuses which are placed inside the drive cabinet.
3. Equip the drive with AC fuses to protect the unit against short circuit. Protect
each input terminal of the supply module with a fuse of its own.
4. Protect the input cable with fuses or circuit breaker which meet the local safety
regulations.
For more information, see Connecting the power cables and busbars (page 61) . See
also Electrical safety precautions (page 56) and the example circuit diagrams.
Cabinet configuration overview
This section shows configuration examples of the supply module cubicles. The 6-pulse
and 12-pulse connections use the same mechanics. The cubicles have direct AC cabling
to the supply module through the bottom plate of the cubicle.
The 400 mm wide design:
• uses Rittal VX25 enclosure or generic enclosures
• can have 1×D8D or 2×D8D modules
• does not have space reserved for internal charging circuit components
• has a swing-out frame for installing the control unit and other electrical equipment.
