Caution! If the operating current execution is programmed for all relays, a failure of
the control voltage or the device will not be detected.
When using as a monitoring device, the operator must ensure that this error
is detected through periodic performance tests.
We recommend programming and correspondingly evaluating at least one relay
in closed-circuit (idle) current execution.
Comply with the maximum permissible temperature when installing in a switch cabinet. Ensure
sufficient clearance to other devices or heat sources. If cooling is inhibited, e.g., through close
proximity to devices with increased surface temperature or interference with the cooling-air current,
the permissible ambient temperature is decreased.
Caution!
Before you apply mains voltage to the device, make sure that the permissible control
voltage

on the side rating plate matches the mains voltage connected to the device!
