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 energised. Before opening the door of the
frequency converter, open the disconnect or circuit breaker
(to de-energise the frequency converter) and remove the
cover of the options cabinet.
For frequency converters purchased with a disconnect,
contactor or circuit breaker, the nameplate label includes a
type code for a replacement that does not include the
MG34U402
Operating Instructions
option. If there is a problem with the frequency converter,
it is replaced independently of the options.
