Please note the following cautions. Mis-operation may lead to personal injury or equipment failure:1) Do not energize the system before installation is complete; never carry out installation activities when the system is energized. Check the correctness of cable connectionbefore you energize the system.2) All peripheral devices must be grounded.3) The conduits of wires under relay must be matched with metaled conduits, other wires can use PVC conduits.4) It is strongly recommended that the length of exposed part of any connection cable should not be longer than 4 mm. Professional clamping tools may be used to avoidunintentional contact of exposed wires to avoid short-circuit or communication failure.5) It is recommended that the control panel be installed at height of 2m above ground, card readers and buttons be installed at height of 1.4m-1.5m above ground.6) It is not recommended that the electrical lock and control panel use the same power supply. It is recommended that the control panel use the provided access controlpower supply or PoE, and the electrical lock use an external power supply separately.Description of normal working state:Connect the system to the power supply. If the system works properly, the POWER indicator (red) is lit constantly and the RUN indicator (green) flashes. If the system iscommunicating, the COMM indicator (yellow) flashes.If the provided chassis is used, the control panel has been installed inside the chassis by default. Fix the chassis on the wall, remove the hole plug or get through the threadhole, connect the access control cable, and install other components.Remarks: The control panel has a guide rail on the back. If you need to install the control panel separately without the chassis, you can use the guide rail to fix the controlpanel. The following figures show how to fix the control panel using the guide rail.C5S120 Installation and Connection GuideVersion: V1.11. Cautions2. Components3.
