Replacing a Pad-Mounted ECN
Important: Before replacing an ECN in the field, visually inspect the unit and
its surroundings to ensure that the unit is not damaged and that it is safe to
handle.
You do not need to reinstall the Pad Mounting Bracket to replace an ECN unit.
To remove a pad-mounted ECN:
1. If possible, use the COS system software to shut down the unit remotely,
before beginning field replacement.
2. Unlock the Conduit Housing and open the Conduit Housing door.
3. Remove all network connections from the bottom of the unit.
4. Remove the power connection from the unit.
5. Remove the screws at the bottom of the unit. These screws are captive,
and remain attached to the ECN.
6. Lift the ECN from the Pad Mounting Bracket.
To install a replacement pad-mounted ECN:
1. Attach the ECN to the Pad Mounting Bracket, as described in Attach
ECN to Pad Mounting Bracket on page 42.
2. Secure the ECN to the Pad Mounting Bracket using the screws at the
bottom of the unit, as described in Secure ECN to Pad Mounting Bracket
on page 43.
3. Connect the ECN to power and to the network, as described in Connect
the ECN to Power and the Network on page 44.
4. Close the Conduit Housing and lock the door, as described in Close and
Lock the Conduit Housing on page 45.
5. Verify successful installation, as described in Verifying Successful
Installation on page 48.
Replacing the Battery Pack
To allow the ECN to run continuously, regardless of external power conditions,
the ECN includes a backup battery option. If your ECN includes this option, you
will occasionally need to replace the batteries.
The battery module is located in its own dedicated compartment accessible from
the outside of the ECN enclosure, as shown in Figure 26 on page 52. Within this
compartment, a blind-mate electrical connector allows easy installation of the
battery module. This separate compartment is weather tight and provides
shielding from sensitive electronics and transceivers.
Important: Removing any of the front panels compromises the factory seal. You
must use the replacement gaskets and sealing screws included with the battery
kit to reestablish a proper seal.
