Indoor DSN-JN-LY 220V 110V Switchgear Lock

Step-by-Step Installation Process

1. Start by removing the M5 nut, spring washer, and flat washer from the panel mounting screw.
2. Place the bolt side of the lock body through the cabinet door opening from the outside. Rotate the lock body to align the mounting screw with the 60mm hole on the cabinet door. Ensure that the lock panel and cabinet door panel are flush and level.
3. Within the cabinet door, assemble the flat washer, spring washer, and M5 nut onto the M5 screw of the lock panel. Tighten the M5 nut firmly to secure the lock in place.

Usage Instructions

(1) Normal Operation

a. To initiate, press the button to activate the power. This action causes the electromagnet coil to separate the moving iron core from the lock bolt stopper. The unlock indicator light will illuminate, indicating the readiness for unlocking.

b. To unlock the cabinet door, turn the handle in the unlocking direction (clockwise for left open, counterclockwise for right open). When the handle reaches its limit position and you continue applying force, the lock bolt will automatically revert to the locked position, allowing the cabinet door to open. If the lock bolt isn't in the unlocked position, it will automatically return to the locked position (auto reset). If the lock bolt is already in the locked position, manually turn the handle to fulfill the locking requirement.

Note: Both A and B locks share the same appearance and installation dimensions.

(2) Operation Method

A. Utilize the dial button. B. Pull the handle.

(3) Manual Unlocking

a. Press the button to disconnect the power supply, deactivating the unlocking light. The moving iron core will adhere to the lock bolt stopper, signifying that unlocking is prohibited.

b. In special unlocking scenarios, use the unlocking key to insert it into the designated unlocking hole. Rotate the key 90° to the "-" (stop position), as indicated on the panel. Push the moving iron core away from the lock stopper.

c. Follow the same steps as the normal operation (step b) to achieve the "manual unlock" status.

Note: The unlocking key serves to release the locked state by pushing the moving iron core. To achieve complete unlocking, the dial or handle must be used, as the key alone cannot directly unlock the lock.
