3.15 Connecting in Series and Parallel
Some of the models in the series are capable of connecting to
another model of the same kind in series or in parallel to double the
voltage output or current output respectively. While these are
possible for some models, some models cannot be connected in
such a way. Please see the below list of warnings pertaining to such
connections.
WARNING:
• Do not connect multiple units of models 9184 or 9185 in
series or in parallel. Due to their high voltage output
design, these cannot be configured to increase voltage
or current in a series connection or parallel connection
setup respectively.
• Only connect multiples units in series or parallel of the
same model. Do not mix models together. For example,
you can connect two 9171 together, but not 9171 and
9172 together.
• Do not connect more than 2 units of models 9174 when
series/parallel tracking is used.
• Do not connect more than 3 units of models 9172 and
9183.
• Never connect more than 4 units at a time in series or
parallel.
• Total voltage output can never exceed maximum 240 V.
• Do not use rear output terminals when connecting
multiple units in series or in parallel. Use front panel
output terminals only.
• When increasing the total output current by connecting
multiple units in parallel, be sure that the connecting
wires have enough thickness to handle the amount of
current. Otherwise, they may overheat and/or drop
voltage levels significantly.
