Figure 2-8 Output modules in parallel with busbars
2.5.5 Current Share Signal Wiring
For modules in constant voltage operation mode, the current share signals of all modules connected in parallel
should be wired together. All ISHARE and D_RTN should be connected. Refer to Section 4.2.1 for the location
of the ISHARE and D_RTN signals in the module connector J2.
2.5.6 Series Modules Connection
Same model modules can be connected in series to achieve higher output voltage. A series connecting busbar
can be used with M8 bolts and nuts as show in the Figure 2-9. When ordered as a system, the required
busbars will be provided to configure the system as ordered. If reconfiguring a system and a busbar is required
for reconfiguration, contact the factory or sales to obtain the needed busbar.
