5. Output (Built-in Relay) Life Expectancy
The insulation system between the power supply circuit and output terminals provides
basic insulation.
Therefore connect the output terminals only to circuits without accessible conductive
parts. If a connection to Safety Extra Low-Voltage (SELV) circuits is desired,
supplementary insulation must be provided.
Use crimp type cable lug terminals with insulating sleeves for wiring.
Be sure to mount a surface-mounting model (H5S- FB ) in a enclosure.
The derating curve shows the load current as a sum of both outputs [A] vs. the
ambient air temperature [˚C] of 2 channel types.
If wires with a temperature rating of 105 ˚C or higher are used, see the derating
curve in the Section 4, "Ratings and characteristics".
