The paralleled modules are programmed as a single, virtual channel with a
current rating equal to the sum of the number of modules connected in parallel.
The master and slave supplies will share the output current equally. Fault
shutdown is coordinated across all modules: a fault within any module of the
group will result in shutdown of all modules.
CAUTION
The outputs of paralleled modules must be wired in parallel at the front panel
output terminals of the units. Use the shortest practical cable length. Operation
of a paralleled module with its return (negative) terminal not connected to the
load could result in damage to the module.
