Multi-Cabinet Parallel Operation Guidelines
Please adhere to the following guidelines when paralleling two or more AFX Cabinet
Systems. Unless these guidelines are following, optimal current sharing between cabinets
cannot be guaranteed.
5.20.1
Output Wiring
1.
All output wires (Neutral, Phase A, Phase B and Phase C) from each cabinet must be
paralleled. Each individual output wire from each Cabinet to the output load
connection MUST BE THE SAME LENGTH AND WIRE SIZE.
2.
DO NOT connect any power wiring between the cabinets. The output wiring from
each cabinet must be brought to a common load termination point.
3.
Keep all power connections between the AFX cabinet and the load termination
point as short as possible.
Note
AC input, AC Load, sense wiring and output junction terminal blocks are
NOT
included with the power source cabinet and must be supplied by the end-user. Only internal
cabinet wiring and terminal blocks are included.
See diagram below for three phase output configuration parallel cabinets.
