Solution: When the upper cabinet door is already open, pull the long interlocking rod inside the upper cabinet door down to the right place to insert the key; When the upper cabinet door is already closed, use pointed nose pliers to push the slots on both sides of the key hole to the horizontal position to insert the key.
4.5.2 Operation of closing and opening the middle cabinet door
▲ Before closing and opening the middle cabinet door, please confirm that the circuit breaker handcart and PT handcart are at the test position.
▲ When the circuit breaker handcart and PT handcart are in the working position, the middle cabinet door will be forcibly locked, and it is strictly prohibited to open the cabinet door. In case of emergency, a 5 # Allen wrench can be used to unscrew the M8 yellow ball head bolt in the middle of the cabinet door and unlock it to open the cabinet door.
(1) Closing of middle cabinet door:
Lift the operating handle of the cabinet door outward with the right hand, press the palm of the left hand against the lower position beside the operating handle, firmly close it forward, and then buckle the operating handle inward.

① . If only the lower side of the cabinet door is not fully closed, the operating handle will not be able to be fastened in. At this time, you can pat the lower side of the middle cabinet door with your palm.
② If the cabinet door cannot be fully closed, the operating handle will not be fastened inward. At this time, check whether the upper, middle and lower studs of the cabinet body touch the upper, middle and lower positioning holes in the middle cabinet door. If they do, adjust the corresponding studs.
③ If the cabinet door cannot be fully closed, the operating handle will not be able to be fastened inward. At this time, the long interlocking rod inside the middle cabinet door should also be checked for deformation. If it is deformed, it should be removed and readjusted.
④ If the cabinet door cannot be fully closed, the operating handle will not be able to be fastened inward. At this time, check whether the “L” shaped handcart unlocking piece in the middle cabinet door cannot be fully inserted into the black interlocking block in the middle of the handcart.

▲ Before the operation of closing and opening the lower cabinet door, for PT cabinet or isolation cabinet, please confirm that the high voltage is not charged, the secondary control power supply is energized, and the door locking electromagnet DTN of the lower cabinet door is energized.
▲ If the above two requirements are not met, the lower cabinet door cannot be closed and opened. In case of emergency, a 5 # Allen wrench can be used to unscrew the M8 yellow ball head bolt in the middle of the cabinet door and unlock it to open the cabinet door.
(1) Closing of lower cabinet door:
Lift the door handle outward with the right hand, press the palm of the left hand against the lower position beside the handle, firmly close it forward, and then buckle the handle inward. be careful:
① . If only the lower side of the cabinet door is not fully closed, the operating handle will not be able to be fastened in. At this time, you can pat the lower side of the middle cabinet door with your palm.
② If the cabinet door cannot be fully closed, the operating handle will not be fastened inward. At this time, check whether the upper, middle and lower studs of the cabinet body touch the upper, middle and lower positioning holes in the middle cabinet door. If they do, adjust the corresponding studs.
③ If the cabinet door cannot be fully closed, the operating handle will not be able to be fastened inward. At this time, the long interlocking rod inside the middle cabinet door should also be checked for deformation. If it is deformed, it should be removed and readjusted.
(2) Opening of lower cabinet door:
① For high-voltage cabinet with grounding switch, after confirming that the grounding switch is in the closing position, lift the operating handle of the cabinet door outward with the right hand and pull it outward to open the cabinet door.
② For PT cabinet or isolation cabinet, confirm that the high voltage is not electrified and the secondary control power supply is electrified. After the door locking electromagnet DTN of the lower cabinet door is electrified, press down the slide of the operation hole between the middle door and the lower door with the left hand, and pull the operation handle of the cabinet door outward with the right hand to open the cabinet door.
Note: If it is difficult to open the cabinet door, it is generally caused by the sagging deformation of the cabinet door. At this time, a large slotted screwdriver or crowbar can be used to pry outward from the gap on the upper edge of the middle cabinet door to open the cabinet door. Then use a hammer to knock down the upper, middle and lower studs of the cabinet body evenly, so that the opening of the lower cabinet door is easier.
