How to set up parallel operation of TDK Lambda power supplies

Only power supplies of the same model ( e.g 8V-150A or 50V-30A ) can be connected to increase the output current. Up to 3 slave supplies can be connected to one master supply. The control connection is made only via the master supply.
• prepare master and slave setup
  1. switch the power on
  2. press the FINE button for three seconds
  3. rotate the CURRENT encoder for the master to the appropriate setting according to the total number of supplies (H2 for 1 slave, H3 for 2 slaves, H4 for 3 slaves)
  4. for the slave rotate the encoder to S (for slave)
  5. press FINE button again and release or wait at least 5 seconds
  6. switch off the power to store the setting in NVRAM
  7. Front panel display after master/slave set up:
     
• make local programming connections
  1. (on the slave(s) (?)) set switch SW1 position 2 to ON position
  2. cable pin 25 on connector J1 on master to pin J1-10 on all slaves (vertically)
  3. connect pin J1-8 to pin J1-12 on all slaves (locally)
  4. Switch SW1 settings and local programming cable:
     
• make solid connections between all +V0 terminals and all -V0 terminals and connect to load
  • The good connection between the -V0 terminals is essential for safe operation.
  • Solid output power connections:
    
• To restore to original setting (single supply)
  • remove local programming cable
  • on master and slaves
    1. press FINE for 3 seconds, rotate CURRENT encoder to H1
    2. press FINE button again and release or wait at least 5 seconds
    3. switch off to store in NVRAM
  • (on the slave(s) (?)) set SW1 position 2 to OFF position
