when wiring
(2) Ground Wiring of the Network Power Unit

CAUTION
1. Be sure to turn OFF the power before wiring cables. Failing to do so could cause electric
shock.
2. Use crimp-on connectors with sheath or cover the conducting part with tape when wiring your
T2/T2E/T2N power module. Also, handle the terminal block cover correctly to avoid fall-off and
damage when fixing. Be sure to fix the cover on the terminal block when completing the
wiring. If the conducting part is exposed, you can have electric shock.
3. Be sure to have grounding. When not grounded, electric shock and/or malfunction can occur.
4. Make sure the wiring is correct when connecting the DeviceNet cables to the network side
connector. The short circuit of the network power, etc. can fail communication with other
nodes.
5. When you are going to detach or connect the network side connector to/from the device side
connector on the DN211 front panel, don't engage yourself while the T2/T2E/T2N side power
is rising. Failing to do so can cause the DN211 to fail or malfunction.
6. Attaching the opposite end of the network side connector with/from the device side connector
is not possible because of the specific form. Trying connecting the wrong end by excessive
force can damage both the network side connector and the device side connector.
7. Ask a qualified person to wire cables. Incorrect wiring can cause fire, failure, and/or electric
shock.
