56 Assembling the DC Input Power Cable
APPENDIX B
Assembling the DC Input Power Cable
To assemble the DC input power cable:
1. Prepare the power wires as specified in “Wiring Requirements” on
page 54 .
2. Use the disconnect device to make sure that the power supply from
the DC power source to the cables is switched off.
Caution: Turn off the power before proceeding with these
instructions.
3. Unplug the WAGO power connector from the power socket on the
NSG back panel.
4. Identify the three wires coming from the DC power source that are
used in the connection to the expansion unit:
■
–Vin
■
+Vin
■
GND
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.
See the pin-out figure below to match wires with the required holes.
