Installation Guidelines

• Mounting: Install the relay on a standard DIN rail within a protected electrical enclosure to prevent exposure to environmental contaminants.
• Probes: Ensure the liquid level probes are installed at the required sensing levels and are cleaned periodically to prevent mineral buildup, which can cause false readings.
• Wiring: Connect the probes and load contacts according to the specific wiring diagram found on the device housing or the original manual.
• Grounding: Maintain a consistent reference ground for the conductive liquid to ensure accurate probe detection.
• Safety: Always verify that the control circuit voltage matches the relay specifications before commissioning.
