• Connect Sense (twisted pairs) to Load point.
• Connect J2 connector of both Racks by Cable (for cable construction see Table 3.9).
• Slave - Disconnect connection between VPROG and TRIM (J1.5 and J1.6).
• Slave - Switch SW1 to “OFF” position (applicable for HFE2500-xx /S PMBus option). For addressing refer to Table 1.5.
• Output Voltage can be adjusted by the trimmer on Master Rack.
Table 3.9 Rack Interconnection Cable.
RJ45 Shielded Male Connectors should be used.
Cable must be shielded; only connector shields are connected to cable shield.

3.10 Series Rack connection
Up to 2 racks with the same number of power supplies and rating (voltage and current) can be used to increase the output voltage.
To connect two Racks in series:
• Connect Main Output (bus bars) in series;
• Connect Sense (twisted) to Load point (as shown in fig-3.10), or use Local Sensing using supplied Control Plugs.
• In case PMBus is used, Connect J2 connector of both Racks by Interconnect Cable for Serial connection (for cable construction see Table 3.10)
;
CAUTION
Do not use Cable as of Table 3.9.
• On one Rack put Switch SW1 to OFF position (only for HFE2500-xx /S PMBus option). For Addressing see Table 1.5;
• Output Voltage can be adjusted by potentiometers on both Racks.
RJ45 Shielded Male Connectors should be used. Cable must be shielded; only connector shields are connected to cable shield.
Diodes should be connected in parallel with each unit output to prevent reverse voltage. Each diode should be rated to at least the
power supply rated output voltage and output current.
WARNING
Do not connect -SENSE and any signals referenced to -SENSE between two Racks. Only signals referenced to SIGNAL RETURN
can be connected between Racks.
