Connecting Power to the Reader – All Types
IMPORTANT!
Finish installing the Reader before applying power.
All Readers come with a 24V, 700 mA wall adapter that plugs into a
110 outlet. If uninterruptible power is an issue, a UPS can be used.

Grounding the Reader
The Reader needs to be properly grounded. Failure to ground the
Reader will result in erratic performance.
Step 1:
Run 14 AWG wire from a solid earth ground to the ground
lug on the outside of the Reader case (Figure 6).
Step 2:
If the Reader is connected to a Wiegand control panel,
ensure that the Wiegand control panel is similarly
grounded.
AC Adapter
The AC adapter wires (Figure 14) are labeled as follows:
