Cautions when using capacity load
Use protection circuit as below to minimize the effect of a load with
high inrush current.
Use an external fuse to protect against overload
N Units embedded with fuse can prevent damages in case of output
shortage.
N Since the unit with embedded fuse cannot protect all the
components against overload, it is recommended that you use an
external fuse for every point.
N The components of output unit may not be protected in case of
shortage.
Cautions for leakage current
A low-current load may not be OFF due to leakage current in the SSR
output unit. In such a case, connect a resistor in parallel with the load.
Common cautions for I/O module
Input/output/motor cables should be separated from each other.
Separate input/output wirings from power wirings as far as possible.
Do not let them pass the same duct and do not bind them together.
Separate I/O and motor cables from high-voltage cables at least
100mm.
