To supply power to the DCP551, use an instrument-dedicated single-phase power sup-
ply subject to minimal electrical interference.
200 to 240/200 to 240V
110 to 120/110 to 120V
Insulating transformer
• If electrical interference proves excessive, we recommend adding an insulat-
ing transformer and/or using a line filter.
model No.: 81446364-001
• After carrying out interference reducing measures, do not bundle the primary
and secondary power supply coils together or insert them in the same conduit
or duct.
If grounding the shield wire or other lines proves difficult, ground them separately to a
grounding terminal block.
