Mounting type: Front-mounted
Compatibility: Designed for LSiS contactors
Function: Signal feedback and circuit expansion

How to use

To install the LSiS UA-4 2a2b, ensure that the main power supply to the contactor is completely disconnected to prevent electrical hazards. Align the auxiliary contact block with the front mounting interface of the compatible contactor and press firmly until it clicks into place. Once secured, connect the control wiring to the appropriate terminals according to your circuit diagram. Verify that all connections are tight and that the contactor operates smoothly before restoring power to the system.

What to consider before purchase

Verify compatibility with your specific contactor model
Ensure the contact configuration (2NO/2NC) meets your control logic requirements
Check available space in your control cabinet for front-mounted accessories

Usage recommendations

Always perform a functional test of the auxiliary contacts after installation to confirm that the signal feedback matches the contactor state before putting the equipment into full operation.
