PRECAUTIONS FOR USE 1) Confirming the supply voltage *Use t h i s unit w i t h i n the s p e c i f i e d range. The unit's rated voltage i s single-phase 100/120/200/220/240VAC ±10X (max. 250V) at 50/60Hz. *The rated voltage i s indicated on the specification and name plate located beside the input connector on the rear panel. -

6. OPERATION PROCEDURES 6-1. Stand-alone operation *When using the power supply in stand-alone, simply operate by manipulation of the panel switches as needed. However, be sure that the MASTER/SLAVE switch i s set to MASTER. 6-2, Serial connection Two or more u n i t s of the power supply can be hooked up i n s e r i e s to achieve in increase in output voltage. -
Page 11: Operation In Parallel
Parallel operation (master-slave control) *Two or more units of the same machine can be hooked up in parallel to give an increase in output current. The total output current w i l l be the sum of the output currents of the individual machines. * In p a r a l l e l operation, one machine wi11 act as the masster and a l l others wi 11 act as slaves. - Page 12 Hook-up front panel terminals in the parallei operation mode.
