MuIti-Cabinet Parallel Operation Guidelines
Please adhere to the following guidelines when paralleling two or more ADF 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 ADF cabinet and the load termination
point as short as possible.
See diagram on next page for three phase output configuration parallel cabinets.
5.20.2
System Grounding
1.
All ADF Cabinet systems MUST be properly grounded to the local facility ground
using the provided GROUND terminal on the AC input terminal block located inside
the cabinet.
2.
In addition to individual facility ground connections, Multi-Cabinet units must be
grounded to each other. This may be accomplished by connecting a ground cable to
the rear of the cabinet rack on the designated Master Cabinet, passing the cable
through the Input / Output power strain reliefs, and terminating the cable on the
rear of the cabinet rack of the designated Auxiliary cabinet.
Refer to diagram above for suggested ground wire routing between two cabinets.
NOTE:
Each cabinet should still be ground to facility ground.
