3.8 PARALLEL CONNECTED UNITS
To achieve higher output power than what is available from one unit, you
can connect up to six units in parallel. This is referred to as ‘master/slave’
operation.
For a master/slave configuration, designate one unit as the master and the
others as slaves. This is done by both switch settings (see Section
SECTION 4) and wiring connections. Connect the master as described in
the preceding steps. Additionally, using the same size and type of wire,
make these connections between the master and slaves:
Connect from Master Unit: To Slave Units:
INPUT LINE INPUT LINE
INPUT GND INPUT GND
INPUT NEUT INPUT NEUT
OUTPUT LINE OUTPUT LINE
OUTPUT NEUT OUTPUT NEUT
Connect the master unit’s sense leads either locally or to the load. Do not
make any connection
to the slave unit’s SENSE terminals. In addition to
the connections just defined, connect a cable (Elgar part number 890-497-
40) from the master’s rear panel connector labeled SLAVE OUT to the
slave rear panel connectors labeled SLAVE IN.
3.9 MULTIPHASE CONNECTED UNITS
Two phase, three phase and six phases can be configured by setting the
rear panel switches and attaching cables to connect the units (Elgar part
number 890-497-40). See Section SECTION 4 for parallel and multiphase
configurations and switch settings.
