Product Description

Indoor Medium Voltage Switchgear - Indoor Electromagnetic Lock

Installation Process

Remove the M5 nut, spring washer, and flat washer from the panel mounting screw.
Insert the lock body's bolt side 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, ensuring a flush and level fit between the lock and cabinet door panels.
Inside the cabinet door, assemble the flat washer, spring washer, and M5 nut onto the lock panel's M5 screw. Tighten the M5 nut securely.

Usage Instructions

(1) Normal Operation

a. Press the button to activate the power. This separates the moving iron core from the lock bolt stopper using the electromagnet coil. The unlock indicator light illuminates, signifying readiness to unlock.

b. Unlock the cabinet door by turning the handle in the unlocking direction (clockwise for left open, counterclockwise for right open). As the handle reaches its limit position and you continue to exert force, the lock bolt automatically returns to the locked position, enabling 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 locked, manually turn the handle to ensure proper locking.

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

(2) Operation Method

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

(3) Manual Unlocking

a. Press the button to deactivate the power, turning off the unlocking light. The moving iron core adheres to the lock bolt stopper, indicating no unlocking allowed.

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

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

Note: The unlocking key releases the locked state by pushing the moving iron core. Full unlocking requires using the dial or handle, as the key alone cannot directly unlock the lock.
