Connecting the DC Power Cord
Follow the steps below 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, as
shown in callout 1 of Figure 3-20 . (If the connector is inserted with the upside down, the insertion is
not smooth due to the specific design of the receptacle and connector.)
3) Fix the screws on the two sides of the DC connector using a flat-blade screwdriver until the
connector is secured to the DC power receptacle, as shown in callout 2 of Figure 3-20 .
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.
