Chapter 2 Installing the Encoder
CAUTION: Turn off the power before proceeding with these instructions.
3. Unplug the WAGO power connector from the power socket on the encoder back panel.
4. Identify the three wires coming from the DC power source that are used in the
connection to the expansion unit:
–Vin
q
+Vin
q
GND
q
5. Strip up to 0.3 inches (8 mm) of insulation from each of the wires coming from the DC
power source.
Do not strip more than this length from each wire. Stripping more leaves uninsulated wire
exposed outside the DC connector after the assembly is complete.
6. Insert a small screwdriver into the rectangular hole directly above the hole in the DC
connector where you want to insert the first cable and press down on the screwdriver.
This opens the cage clamp for this section of the DC plug connector.
NOTE: WAGO also sells tools specifically designed to open cage clamps easily. For more information,
either visit the WAGO web site at www.wago.com, or call WAGO at 1-800-346-7245 and request
information about items 210-250 or 231-131.
7. Feed the exposed section of the wire into the matching hole in the DC plug connector, as

NOTE: If you need to remove a wire from the DC plug connector, insert a small screwdriver into the
slot directly above the wire and press down on the screwdriver to free the wire from the cage clamp.
The Boot Sequence
The boot sequence begins as soon as you plug in your encoder. This section describes the
encoder boot sequence, including the messages that appear on the local control panel
display.
Local Control Panel Display Messages during Bootup
Messages on the local control panel indicate progress during boot-up. During a successful
boot, many events occur so quickly you cannot see the messages. The following sections
describe the messages that you can see during boot attempts.
