Table 1.2 Overview of Extended Options
The D7h and D8h frequency converters (D2h plus options
cabinet), include a 200 mm pedestal for floor mounting.
There is a safety latch on the front cover of the options
cabinet. If the frequency converter is supplied with a mains
disconnect or circuit breaker, the safety latch prevents the
cabinet door from being opened while the frequency
converter is energized. Before opening the door of the
frequency converter, the disconnect or circuit breaker must
be opened (to de-energize the frequency converter) and
the cover of the options cabinet must be removed.
For frequency converters purchased with a disconnect,
contactor or circuit breaker, the name plate label includes
a type code for a replacement that does not include the
option. If there is a problem with the frequency converter,
it is replaced independent of the options.
Refer to chapter 3.7 Optional Equipment for more detailed
descriptions of the input options and other options that
may be added to the frequency converter.
