Installer is responsible to provide suitable dc output, battery, and dc load wiring.
Guidelines for DC Connections Guidelines for DC Connections
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.
Voltage Drop per 100ft / 30.5m of Wire (for copper at 68 F / 20 C)

Example: 100ft / 30.5m of #8 AWG wire at 50A has a 3.1V drop. Example
2. 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 (refer to
3. Do not run external ac and dc power wiring through the same conduit.
4. Facility-specific installation requirements take precedence.
PROCEDURE PROCEDURE
1. Identify your ATevo enclosure type (Style-5070, Style-5030, Style-163, or Style-198). Refer
to the applicable image in the sections below.
2. 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.
