Parallel connection of loads

If more than one load is connected to an output channel, use separate wires to
connect each load. This minimizes mutual coupling effects and takes full
advantage of the power supply's low output impedance. Each pair of wires should
be as short as possible to reduce wire inductance and noise pickup. The loads
must be connected in parallel, not in series, so that loads are not mutually
influenced by load fluctuations.
It is advised to use a pair of DC distribution terminals (DT) not located at the
output channel terminals.
Note: In principle, there is no restriction about the number of loads that can be
connected. Remote voltage sensing is recommended if one load is more
sensitive than the other(s); therefore, sense directly at the most sensitive
load.
Local sensing (loads in parallel):

If local sensing is used, locate the distribution terminals (DT) as near as possible
to the output channel terminals.
