Installer is responsible to provide suitable dc output, battery, and dc load wiring.
Follow these steps to connect the battery to ATevo:

  1. Size the dc wiring to minimize voltage drop. Acceptable wire size depends on the installation. As a guideline, voltage drop should not exceed 1% of nominal output voltage at full current. Refer to the following table to determine the voltage drops for various wire sizes, currents and distances.
Wire Sizing Chart
Voltage Drop per 100ft / 30.5m of Wire (for copper at 68 F / 20 C)
Wire Size (AWG) DC Current (Amperes)
6 12 16 20 25
16 2.5V 5.0V 6.7V 8.2V 10.5V
14 1.6V 3.2V 4.2V 5.3V 6.6V
12 1.0V 2.0V 2.6V 3.3V 4.2V
10 0.63V 1.3V 1.7V 2.1V 2.6V
8 0.40V 0.80V 1.1V 1.3V 1.7V
6 0.25V 0.50V 0.66V 0.83V 1.1V
4 0.16V 0.32V 0.42V 0.52V 0.65V

Example: 100ft / 30.5m of #8 AWG wire at 16A has a 1.1V drop.

  1. ATevo is factory wired to regulate output voltage at the output terminals. If total voltage drop is greater than 1% (e.g. 1.3V for a 130 Vdc system), remote sense wiring is recommended (see Section 11, Remote Sense ).
  2. Do not run external ac and dc power wiring through the same conduit.
  3. Facility-specific installation requirements take precedence.

I/O Connections: Style-5054 Enclosure


  1. Use a dc disconnect switch or circuit breaker between ATevo and the dc bus. This device should have lockout capability to allow ATevo to be disconnected from the dc bus for maintenance.
  2. Remove safety shield (see Section 2.2, Removing Protective Safety Shield).
  3. Run dc wiring to Output Circuit Breaker (CB2).
  4. Connect wires to appropriate locations on the DC Output Breaker (CB2+/-) as indicated on drawing above.
  5. Using a flat-blade screwdriver, securely tighten compression screws on DC Output Breaker Terminals (CB2+/-).
  6. Reinstall safety shield after you have made and checked all connections.
