■ Power supply
To supply power to the DCP552 , use an instrument-dedicated single-phase power
supply subject to minimal electrical interference.
Handling Precautions
• If electrical interference proves excessive, we recommend adding an
insulating 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.
■ Grounding
If grounding the shield wire or other lines proves difficult, ground them separately
to a grounding terminal block.
