The reconnection procedure
reconnections only. Some 30kW models are now
available factory-configured for 50 Hz. Do not attempt
to change the frequency from 60 Hz to 50 Hz (or vice-
versa) in the field.
The following instructions explain the reconnection of
12-lead generator sets. In all cases, follow the National
Electrical Code (NEC) guidelines.
Reconnect the stator leads of the generator set if a
different output phase or voltage is desired. Refer to the
following procedure and the connection schematics.
Refer to Section 5 for instructions to make adjustments
though the ADC 2100 menus when instructed in the
procedure. Follow all safety precautions at the front of
this manual and in the text while performing this
procedure.
Note: Order voltage reconnection decal 246242 from
an authorized service distributor/dealer and affix
decal to generator set after reconnecting to a
voltage different than the nameplate.
