Key specifications
 Mounting type: DIN-rail mount for standard TS35 rails
 Connection type: screw/pressure connection for conductor fixation
 Application: wire termination and distribution in control panels
 Compatibility: suitable for standard stranded or solid conductors used in industrial panels
 Mechanical design: compact profile to maximize cabinet space
How to use
Mount the terminal block on the DIN-rail by clipping it into place and ensure it is mechanically secured. Prepare conductors to the required stripping length and insert them into the terminal entry, then tighten the connection mechanism to the recommended torque specified in installation guides to achieve proper contact. For multi-point wiring, use consistent labeling or marking to maintain circuit identification. When modifying or expanding circuits, de-energize the panel and follow standard lockout-tagout procedures before disconnecting or reconnecting conductors.
