2-1 Specifications
This section gives the general specifications and individual Unit specifications of the CIF Units.
The following table gives the general sp
ecifications of the CIF Units.
2-1-1 General Specifications
Item Specification
Enclosure Mounted in a panel.
Grounding method Ground of 100 Ω or less.
If a conductive DIN Track is used, a CIF Unit is grounded through the
DIN Track from the System Power Supply Unit. If a non-conductive
DIN Track is used, a CIF Unit is grounded from the FG terminal.
