6. Installation & Operation Guidelines
7. Installation Steps

Snap-on design for direct mounting on 35mm standard DIN rail

Ensure full and firm engagement between socket and rail without looseness

Cut off power supply before wiring; connect wires according to terminal markings

2. Wiring Specifications

Control wire stripping length within 6-7mm to avoid excessive exposed conductors

Screw torque shall not exceed 0.8Nm to prevent terminal damage

Do not use wires over 2.5mm² under rated current for optimal heat dissipation

3. Maintenance Recommendations

Regularly check terminals for loose connections

Avoid long-term operation in humid and dusty environments

Disconnect power before replacing relays; pull out vertically to prevent pin bending
