Installation and Usage Instructions:
1.Unboxing:Check the integrity of the packaging.Compare the equipment model,specifications,circuit layout,internal cabinet devices,wiring terminals,etc.,with the drawings to ensure they meet the requirements.
2.Installation:Wall-mounted installation.During installation,ensure the verticality and horizontal deviation of the VCS installation.The horizontal deviation must not exceed 2mm/m.After repeated adjustments,secure the VCS in place.Installation dimensions:Refer to the drawings.
3.Wiring:After the cabinet is securely installed,pass the incoming and outgoing cables through the cable fastening bolts according to the drawings,then connect them to the incoming and outgoing terminals of the switch.Cover the incoming and outgoing cable protective covers.Ensure the ground wire is reliably grounded during wiring.
3.Operation:
a)Closing:
Close the door and lock it with the key.
Then turn the handle clockwise upward to close the circuit.
b)Opening:
Turn the handle counterclockwise downward to open the circuit.
After opening,use the key to unlock and open the door.
c)Maintenance:
After opening the circuit,visually confirm through the viewing window that the switch contacts have disconnected.
Pull out the locking device in the middle of the handle and secure it with a padlock.
