Installation and operating instructions

• Mount the switch on a solid surface and ensure that the control element is loaded in the prescribed direction of movement of the mechanism.
• When connecting, verify the function of the 1NO and 1NC contacts and select the correct terminals according to the required control logic.
• Provide suitable mechanical stops to prevent excessive stress on the controller.

Safety notice

• Installation and connection should only be carried out with the power supply disconnected and by a qualified person.
• In circuits with hazardous voltages, improper installation can cause electric shock or damage to the equipment.
• Follow the application requirements for fuses and protection against short circuits and overloads.
