The series connected modules are programmed as a single, virtual channel
with a voltage rating equal to the sum of the number of modules connected in
series. The modules will share the output voltage equally. The output current
is the same for each module. Fault shutdown is coordinated across all
modules: a fault within any module of the group will result in shutdown of all
modules.
CAUTION
To prevent damage to a supply, do not exceed the float voltage
specification limit for either of the output terminals to chassis.
