How to use
Install the Karlik 28DWPUS-3 into a compatible panel cutout and make electrical connections according to the system wiring diagram, ensuring power is disconnected before wiring. Connect the AC supply (up to 250 V) to the input terminals and route the switched output to the control circuit or pump relay, observing the 10 A nominal current rating. Place the switch inside an appropriate cabinet or enclosure to maintain its IP20 level of protection and prevent exposure to dust or moisture. Verify correct operation by simulating liquid levels or performing functional tests after installation.
Usage recommendations
Use this level switch only within enclosed, dry control cabinets or enclosures that meet IP20 conditions. Do not expose the device to direct moisture or outdoor environments without additional protective measures. Match the switch output to compatible relays or contactors when controlling motors or high-inrush loads, and ensure wiring is performed by a qualified electrician following local regulations.
