WARNING!
The ground wire of the access controller should be connected to the grounding system in the
equipment room. The fire main and lightning rod of a building are not good grounding options.
Connecting the power cord
WARNING!
Make sure that the ground wire is properly connected before powering on the access controller.
If the device is AC-powered, connect the device with an external AC power system
through an AC power cord. If the device is DC-powered, connect the device with an
external DC power system through a DC power cord.
Connecting the AC power cord
To connect the AC power cord:
1.
Make sure that the PGND of the access controller is correctly connected. The AC
power cord retainer can prevent the AC power cord from accidentally falling off.
Whether a power cord retainer is needed depends on the power supply system of
the country.
2.
Install the AC power cord retainer to the access controller, and turn the retainer left.
3.
Connect one end of the power cord to either power socket on the rear panel of
the chassis and the other end to the AC power supply.
4.
Turn the power cord retainer right to lock the power cord plug.
5.
Check the corresponding PWR LED on the front panel of the access controller. If the
LED is solid green, the AC power input is normal.
Connecting the DC power cord
To connect the DC power cord:
1.
Make sure that the PGND of the access controller is correctly connected.
2.
Insert the DC connector with upside on top into the DC power receptacle of the
power module. (If the connector is inserted upside down, the insertion is not smooth
due to the specific design of the receptacle and connector.)
3.
Using a flat-blade screwdriver, fix the screws on the two sides of the DC connector
until the connector is secured to the DC power receptacle.
4.
Connect the other end of the power cord to the external DC power supply.
5.
Check the corresponding PWR LED on the front panel of the access controller. If the
LED is solid green, the DC power input is normal.
