Start-up Procedure

Be sure to turn on the circuit breaker at the rear of the slave units before you turn on the circuit
breaker of the master unit. The INPUT POWER LED lights on each unit.

Master/Slave Operation

A master/slave system consists of one 30 kW master unit and from one to three slave units.
Slaves can be either 15 kW units or 30 kW units. The recommended configuration
combinations are shown in the table below.

Note: If the master MDXII is being used as a stand-alone unit, plug the termination plug into
the Slave port.
Connect the master unit's Slave port to the first slave's Prior port with the cable that is shipped
with the slave unit. If you have more than one slave, connect the first slave's Next port to the
second slave's Prior port; do the same if you have a third slave unit. For an illustration and of
the rear of the unit, see Figure B-1 on page B-12. Connect the output of each MDXII to the
chamber independently with separate cables. The current levels are added together under the
control of the master MDXII.
Always power up the slaves first. Then when the master unit is powered up, it can identify
each slave by its signal. If the master unit is turned on before the slave units, it will not
recognize that any slaves exist. In this case, the total system output power is limited to what
the master can produce.
