10.1. Installing the TempCo Option

In overview, there are four (4) stages. The full detailed procedure is found in the next few topics:

• Mount probe assembly (A10) on or near battery.
• Run interconnection cable from probe assembly to ATevo.
• Connect charger-end of cable to terminal block (A2-TB8) on ATevo Power Board.
• Configure ATevo to recognize TempCo option.
  

The TempCo probe (A10), or ‘puck’, is the same for all battery types and all ATevo models, regardless of dc output voltage. Accessory part numbers differ depending on cable length.

PROCEDURE

1. De-energize and lock out all ac and dc voltages to ATevo.
2. Allow internal voltages to dissipate.
3. Remove safety shield and verify no hazardous voltages are present with a voltmeter.
4. Mount probe (A10) on a clean, dry surface on or as close to battery as possible.

!Do NOT mount probe on: unpainted wood, bare galvanized metal, or plastic surfaces. Consult battery manufacturer for mounting restrictions and adhesive compatibilities.

5. To apply probe, clean mounting surface with isopropyl alcohol and dry thoroughly.
6. Remove protective backing from double-faced adhesive tape on probe, and press onto surface.
7. Install supplied cable:

• Route end of cable that has two (2) stripped wires and a quick-connect terminal to the inside of ATevo enclosure.
• Leave 30in / 762mm of cable inside enclosure. Run cable through a conduit that does not contain power wiring.
• Route other end of cable to probe at the battery, and coil up excess cable.
• Make sure all wiring conforms to NEC, local, and site requirements

8. Attach interconnection cable to ATevo Power Board (A2-TB8) and EARTH terminal as shown below:

• Route TempCo cable to lower end of Power Board (A2).
• Locate TB8 and insert one (1) of each of the stripped wires from the twisted pair into each location on the terminal block (A2-TB8). Connection Points are not polarity sensitive.
• Locate the EARTH quick-connect terminal at the bottom of Power Board (A2). Carefully pull off the quick-connect terminal and wire from the EARTH terminal.
• Plug the quick-connect terminal attached to the end of the TempCo cable’s shield wire onto the Power Board’s EARTH terminal.
• Connect the quick-connect terminal removed from the EARTH terminal to the ‘piggy-back’ terminal on the end of the TempCo cable’s shield wire.
• Fasten the TempCo cable to existing wire harness with plastic wire ties.

9. At the battery, connect the quick-connect terminals to the TempCo probe (A10). Connection points are not polarity sensitive. Coil up and wire-tie any excess wire to prevent damage.
10. Confirm that:

• All connections are secure.
• Both the TempCo shield and the original ground wire are connected to the EARTH quick-connect terminal (A2-EARTH).
• The twisted-pair wires of the TempCo cable are connected to the 2-position terminal block on the Power Board (A2-TB8).

11. Replace the safety shield and close the front panel door.
12. Restart the ATevo.

Configuring the TempCo Option

ATevo will need to be configured to enable the TempCo probe (A10) and to select the battery type. Refer to Section 6.3 for both.
