• The individual wires extending from the reader are color-coded
according to the required Wiegand standard.
• When using a separate power supply for the reader, this supply and
the controller’s power supply must have a common ground. A linear
power supply is recommended.
• Attach the cable shield wire on the reader to an earth ground (best),
or to a signal ground connection at the panel or power supply end of
the cable. This configuration is best for shielding the reader cable
from external interference.

Attach the cable shield wire on the unit to an earth ground (best).
You can also attach it to a signal ground connection at the panel or
power supply end of the cable. This configuration is best for
shielding the controller cable from external interference.

cable jacket back 3.2 cm (1¼”) and strip the wire 1.3 cm (½”).
3. Splice the controller pigtail wires to the corresponding PS-x25x
secured power supply’s wires and cover each joint with insulating
tape.
