Note: When using no-voltage input (NPN input).
Input Connections
The inputs of the H5CX-A@/-A11@ are no-voltage (short-circuit or open) inputs or voltage inputs.
The input of the H5CX-L8@ is no-voltage input only.
Note: Power circuit is not insulated from the input circuit, except for H5CX-A11/-A11S, which have basic insulation. For wiring, refer to Safety Pre-
cautions (H5CX-A/-L) on page 49.
