11.3. Procedure for Wiring Remote Sense

Route twisted-pair cable between the battery and ATevo. Make the connections listed below before moving the Remote Sense enable jumpers to enable the Remote Sense.

Preparation:

• Open both front panel breakers (CB1/CB2).
• De-energize and lock out all ac and dc voltages to ATevo.
• Allow internal voltages to dissipate.
• Use #16 AWG twisted-pair wire, of appropriate length to reach from the battery to ATevo.
• Designate, or label, one (1) wire of twisted pair as ‘DC(+)’.
• Designate the other wire of the twisted pair as ‘DC( – )’.
• Route one (1) end of the twisted pair remote sense wiring to BATTERY, at the desired battery sense location.
• Open ATevo front panel door, and remove safety shield.
• Verify no hazardous voltages are present with a voltmeter.
• Locate the Power Board (A2) on the left side of ATevo.
• Refer to image below.
• Identify the 3-position REMOTE SENSE terminal block (A2-TB1) at the bottom-front of the board.
• Route other end of twisted pair wiring to terminal block.
  

Wiring

• Connect wire from twisted-pair designated as ‘DC(+)’ to terminal (A2-TB1-POS).
• Connect wire designated as ‘DC( – )’ to terminal (A2-TB1-NEG)
• Observing correct polarity, connect battery end of ‘DC(+)’ wire to a positive sense location on the battery.
• Confirm polarity and connect battery end of ‘DC( – )’ wire to a negative(-) sense location on the battery.
• Verify polarity of POS and NEG battery connections.
• DO NOT energize ATevo until you configure Remote Sense jumpers per Section 11.4.
• After Remote Sense Jumpers have been correctly configured, replace the safety shield and re-energize ATevo.
  

Notes

• Maximum current is 150mA.
• Run the twisted-pair cable with the sense leads in a dedicated conduit.
• Fuse each of the sense wires.
