Safety Precautions (continued)
•
Mounting/removing the module
CAUTION
1. Since the DN211 is designed for the T2 series, be sure to attach it to the base unit.
Don't use your DN211 in stand-alone state or to other applications.
Failing to do so could cause electric shock, injury, and/or failure.
2. Be sure to turn OFF the power before mounting, removing, wiring, or un-wiring the
DN211. Failing to do so can cause electric shock, malfunction, and/or failure.
3. Keep your DN211 free from foreign matter such as electric-wire waste. Failing to do
so could cause fire, failure, and/or malfunction.
4. Check the connectors and cables and the DN211 mount in the base unit, for their firm
connections and mount using stoppers/screws. Loose connection and mounting
becomes shaky and disconnected, resulting in failure or malfunction.

Wiring the power and grounding
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.
