POWER SUPPLY REQUIREMENTS
The G304K2 requires a 24 VDC ±20% power supply. Please take care to
observe the following points:
- The wire used to connect the operator interface’s power supply should
be at least 22-gage wire. If a longer cable run is used, a heavier gage
wire should be used. The routing of the cable should be kept away from
large contactors, inverters, and other devices which may generate
significant electrical noise.
- A power supply with a Class 2 or SELV rating is to be used. A Class 2
or SELV power supply provides isolation to accessible circuits from
hazardous voltage levels generated by a mains power supply due to
single faults. SELV is an acronym for “safety extra-low voltage.”
Safety extra-low voltage circuits shall exhibit voltages safe to touch
both under normal operating conditions and after a single fault, such as
a breakdown of a layer of basic insulation or after the failure of a single
component has occurred.
PC CONNECTION
Configuration files are downloaded to the Kadet 2 via the PC port, which can
be connected to a computer via various cables.
