Quantity 1 1 1 2
Comments MIU pipe including cable
Labels with MIU serial number
4.2 Storage
Store the product in a cool and dry environment. Storage temperature should be below +30°C to save battery lifetime (between +20°C to
+30°C). Storage of more than one year may affect product battery lifetime.
4.3 Installation
Please follow these steps to install the MIU in a Pit:
1) Remove the meter pit lid. 2) Attach the MIU cable to the meter using the appropriate Nicor or Bare wire
connections (Figure 4: wires pinout connections). Verify the meter and MIU connectors are clean and dry before connection. 3) To activate the MIU attach a magnet for more than one second. (Figure 5: Magnet location for MIU activation). 4) Verify the installed unit status using the Activator BT tool to read the MIU data. (Figure 6: MIU magnet status to activator). For further information about Activator usage, check its user manual. 5) Pass the plastic Nut through the MIU cable and screw few turns through the MIU main body thread. 6) Insert the MIU main body through the Lid hole from the lid cover bottom.

User Manual
7) Screw the plastic top cover over the top pipe body and fasten the unit to the meter pit lid using the plastic nut until the MIU pipe is tied to the pit lid.
8) The MIU main body should be beneath the meter pit lid, while the plastic top cover is tied to the top of the pit lid.
9) Verify all electrical and mechanical connections. 10) Close the meter pit lid.

4.4 Troubleshooting
1. No MIU status in the Activator BT tool: Check the MIU cable connected and locked to the encoder cable. Attach the magnet to the MIU. Verify the installed unit status using the Activator BT tool to read the MIU data. 2. MIU fail to switch to Active mode after auto-detect: Repeat step 1. When MIU fail to switch to active then cable is damaged, or the encoder is not
supported.
